The Advantages and Disadvantages to Bug Tracking Software

Bug tracking has been around as early as the 1940’s, just not in a software form. In these early days, simply using a pen and a paper created tracking systems. It evolved from then to using spreadsheets. Now there is bug tracking software like the defect tracking tool and even more specific programs like Mantis and Bugzilla, just to name a couple. As with anything that evolves however, there will always be those that are 100% for the programs and those that are against it. This article will cover all claims – both positive and negative – of bug tracking software like the defect tracking tool.

The Positive Claims

It certainly depends on the type of bug tracking software that is used, but it seems as if there are many more advantages to these tools than disadvantages. The most obvious advantage is that these types of tools allow companies to keep a record of the issues that are recorded, who fixed them, and even how long it took to fix the issue for some types of programs. Customers are encouraged to be as detailed as they can be when requesting that an issue be fixed so that companies can complete their requests as quickly as possible. The fact that the issues are recorded and saved is a huge benefit for the companies because sending the recorded bug list with the purchased software is a common practice. This is a benefit to customers because if it is a common error, they can simply look up this issue in the previously recorded bug list. However, if the list is incredibly long (a common disadvantage) it can become more of a hassle.

The Negative Claims

As with anything that has a list of positive aspects there is also a list of negative aspects, though there are few. One of the biggest complaints is not so much from the bug tracking software or defect tracking tool itself but more from the process of submitting issue requests. Customers need to be extremely detailed with their issue requests if they want a detailed response. Miscommunication isn’t a fault of the product, the customer, or the company – it’s simply something that happens. Customers and companies alike both need to remember to be patient with each other and to treat each other with a mutual respect. A second complaint that was previously mentioned is the length of issues in some of these software programs.

Some customers don’t have the patience to look through a long list of software issues that have been previously recorded and this causes frustration among the companies that took the time to purchase software that saves them. The length of issues that are submitted can also become a problem because if there are too many issues submitted and not enough engineers to address them, some can get overlooked. Nobody likes to be forgotten, but usually these types of bug tracking software include detailed instructions and are easy to use.

Usually when a company purchases a bug tracking software or defect tracking tool it already has an experienced IT department in place. Whatever the software is that is being used with these programs should have some sort of backup for when the work is completed so it does not get lost if the issues that occur are deadly.

Corel DRAW – Best Desktop Publishing Software

Corel DRAW is a supreme supplier of graphics software, including the popular Corel DRAW program. Corel DRAW has tools that allow the user to both create and edit images. The type of desktop publishing tools that you use will depend on the type of project. For more information and assistance, use the Corel website.

Corel DRAW is the best Desktop publishing software that empowers users to create illustrations containing graphics, text and photographs. Corel has an extensive range of tools which enable the user to edit any shape or character with ease and precision, fit text to curves and create custom color separations. It is developed and marketed by Corporation of Ottawa. This tool can open files: Adobe PageMaker, Microsoft Publisher and Word, and other programs can print documents to Adobe PDF using the Writer printer driver, which such software can then open and edit every aspect of the original layout and design.

Several innovations to vector-based illustration originated with Corel: a node-edit tool that operates differently on different objects, fit text-to-path, stroke-before-fill, quick fill/stroke color selection palettes, perspective projections, mesh fills and complex gradient fills.

One of this software’s many strengths is the huge range of over 1,000 fonts that it comes with, provided in both TrueType and Postscript Type 1 format. Corel differentiates itself from its opponent in a number of ways: The first is its positioning as a graphics suite, rather than just a vector graphics program. A full range of editing tools allow the user to adjust contrast, color balance, change the format from RGB to CMYK, add special effects such as vignettes and special borders to bitmaps. Bitmaps can also be edited more extensively using Corel PhotoPaint, opening the bitmap directly from Corel and returning to the program after saving. It also allows a laser to cut out any drawings.

Expert believed it was the first of the Windows-based drawing programs and has built on this early start to become far-and-away the dominant drawing package on the PC. Its biggest strength – and its biggest potential limitation – is its all-encompassing approach. In the past this has led to accusations of unfocused bloating, but with version 7.0 Corel has addressed the criticisms with a far tighter and better rationalized program. Even so, there’s a huge range of functionality to cover.

Corel DRAW Download was originally developed for Microsoft Windows and currently runs on Windows XP, Windows Vista, and Windows 7. The current version, X5, was released on 23 February 2010.

Review of Takeoff Software for Estimating Construction

So often people want to rush out and buy estimating software or takeoff software without first trying to define their internal estimating processes. Once the estimating process is clearly defined, then and only then, can you actually try to compartmentalize the process into segments. So often the segment is really quantity takeoff. Takeoff of what you may wonder? That is like the million dollar question. This article will speak about the takeoff software process which usually associated with estimating software processes. The takeoff software process can often be takeoff of materials for some folks, and to many others, the takeoff process of scoped systems to create estimates or proposals. This review or comparison will not try to explain the estimating software process but bring to you valid quantity takeoff thinking among estimators in a quest to find which product thinks the way you do. These are the opinions of the author.

I will review and compare 3 types of measuring takeoff products:

It is extremely important to note that these are ONLY measuring takeoff programs, NOT estimating programs.

1) Planswift

2) On-Screen Takeoff by On Center Software

3) Electronic Plan Takeoff Software

All three products have their strengths, however, Planswift and On-Screen Takeoff are stand-alone products and Electronic Plan Takeoff is actually dynamically integrated live with Microsoft Excel which means that it starts and finishes and saves in Excel. They all integrate with Excel, however, you will have to evaluate your thought process and decide which of the three products work-flow think along the lines of how you think. For instance, what is the first thing you do when you get a set of plans? Typically, you start flipping through the plans to see how involved the project is and what type of work do you see that is attractive for your company. Then when you decide you are going to estimate this job, more often than not, you start like 80% of companies in the world of construction estimating by opening your takeoff master template Excel spreadsheet. You rename your spreadsheet to the new job or project and off you go performing takeoff. This is where the differences are:

In Planswift, you decide what drawing you are on and then you perform the measuring of an item you want to perform takeoff on the plan. Unfortunately, that is not exactly how an estimator thinks. Planswift does give you the ability to add a type of takeoff item on the fly by naming it and then perform takeoff of it; somewhat of a very manual and slow process. They also provide you with the ability of applying a type of assembly to a takeoff to aggregate quantities of items in that assembly. Not quite the way an estimator thinks. It forces you to jump to different screens which slows down the process. Typically, the main start of anyone’s takeoff process, or some may think of it as a checklist approach, is to start with your own spreadsheet of YOUR items. Those items can be material items or can be scoped assembly system items. Either way, by starting with a master spreadsheet say in Excel for example, many estimators think of this as a risk reducer, not to forget things they normally takeoff. Being that Planswift is a stand-alone takeoff program, it typically saves your takeoff images in Planswift instead of your estimate in Excel, if Excel is your estimating system. If you are using Excel, you have to manually save your takeoff measurement numbers in Excel and your takeoff images in Planswift or elsewhere, just not in Excel where the takeoff quantity resides. Again, if you want to integrate with Excel, they force you to either export or import takeoff items from Excel rather than being dynamically integrated live to Excel. They do however have the ability to dump the measured quantity from Planswift into any Excel spreadsheet or Word document. The main purpose or the primary focus of this program is measuring, therefore it does a good job at that function. Most of the other functions require you to jump around different screens, and essentially, you loose your thought of where you are. There are some features that attempt to address the estimating process, however, there are many features that are missing for Planswift to be a full fledged estimating system; it is NOT one. Planswift does integrate with the leading estimating system Sage Timberline, but the integration is weak. Since Timberline’s power is in assembly takeoff and where most estimators reside in Timberline, Planswift does not give the estimator the ability to add quantities of miscellaneous Timberline items or one-time items that need to added on the fly to an assembly while they are in Planswift at the Timberline interview screen, and while being in the measuring phase. Planswift does allow the deleting of assembly generated items as well adjusting assembly item quantities in a different screen. Again, to perform all that, you are forced to jump around to different screens. No assembly is ever perfect in any estimating system since project conditions are always uniquely different, therefore, having to add items to an assembly is extremely important. That adding of items and associated quantities is an absolute requirement any estimator typically has to do during the takeoff measuring and estimating phase; something that Planswift struggles with as related to Timberline Estimating. Planswift does allow the direct send of measurements to Timberline Estimating items and assemblies while in Timberline Estimating, just as you would do with the old digitizer measuring boards. Training, support and maintenance are extra for Planswift. On-Screen Takeoff by On Center Software, and Planswift charge their annual maintenance and support fees per license (mandatory) which costs the end user more expense annually especially if a customer has more than one license.

On Center’s On-Screen Takeoff is the Grand Daddy of software takeoff products due to the fact that it has been around the longest. On Center recognizes that On-Screen Takeoff is primarily a measuring program. That is why they have a separate estimating program named QuickBid for those who want an estimating program. On Center does not try to trick you into thinking it is an estimating system. In On-Screen Takeoff, you also decide what drawing you are on and then you perform the measuring of the plan. BUT, before you start, you can load a master set styles of things you typically takeoff or measure from your own library. That process seems to be less complicated than that of Planswift. On-Screen Takeoff does give you the ability to add a type of takeoff item on the fly by naming it and then performing takeoff of it; somewhat of a manual and slow process as well. The program does come with many features that are primarily focused on simple measuring to advanced measuring issues all with attention to detail regarding easy navigation for the takeoff process. On Center does a very good job at that. However, there seems to be a disconnect of thought from an Excel spreadsheet items you may use for estimating and/or proposals. The integration to Microsoft Excel is not a dynamic live link, more like an after thought in my opinion. Yes, you can establish links to named styles to cells or ranges in Excel, somewhat rigid. But the question you will have to ask yourself, which will happen more often than not is: What do you do when you need to add things on the fly during takeoff and in an Excel spreadsheet? Again there will be manual associations you will have to establish with Excel which is another major slowdown. You have to manually save your takeoff measurement numbers in Excel and your takeoff images in On-Screen or anywhere you decide, except the takeoff images will not be saved in Excel where the takeoff quantity resides. This type of situation arises when a takeoff program is a stand-alone program. On Center’s On-Screen Takeoff has the best integration with the most widely used estimating system in the USA: Sage Timberline Estimating. It basically mimics the same interview process as you would do with the old digitizer measuring boards. By working directly with Timberline, On-Screen Takeoff allows the estimator to perform takeoff of a Timberline variable question and immediately returns back directly with the takeoff quantity in a Timberline assembly at the variable question. By virtue of this process, On-Screen Takeoff allows the estimator to continue his/her Timberline interview process in Sage Timberline Estimating by reviewing/massaging generated quantities, or adding items in a Timberline assembly as the estimator see fit. That workflow process gives full control to the estimator, good job On Center. Training, support and maintenance are extra for On-Screen Takeoff. On-Screen Takeoff by On Center Software, and Planswift charge their annual maintenance and support fees per license (mandatory) which costs the end user more expense annually especially if a customer has more than one license.

This next system is ONLY if your estimating system or proposal generator is Microsoft Excel. Electronic Plan Takeoff Software is a plug-in for Excel. You start your spreadsheet, you perform the measuring takeoff, you may even add some more items on the fly all the while you are in the measuring phase in the Electronic Plan Takeoff program. When you are done, even if you added items on the fly, they automatically appear in your Excel spreadsheet. Excel is the control of everything. Your project is started in Excel, your takeoff is saved in Excel, the estimate or proposal is/can be produced there in Excel; one program, one place. Many takeoff programs interface with Excel somehow, but only Electronic Plan Takeoff is live linked with Excel, meaning all your Excel spreadsheet descriptions appear in the measuring takeoff program so you always know where you are in Excel. That is a huge difference in comparison to Planswift and On-Screen Takeoff. You can even change a description of a takeoff item in Electronic Plan Takeoff and it is automatically changed live, in your Excel spreadsheet. When you talk about the estimating and takeoff phase you must keep processes cleans and easy and this program does just that. There is no getting lost in this program. Just like the other reviewed programs above, the central focus of this program is takeoff measuring, and it does a GREAT job at that. The navigation within the program is really simple and easy. It is not made to work with other estimating systems, but there is a version that allows the direct send of measurements to any Microsoft Windows program awaiting a keyboard entry, just as you would do with digitizer measuring boards. There is also a version that works with digitizer boards as well. If you use Microsoft Excel for estimating, or takeoffs, or proposals, then this Electronic Plan Takeoff program for Excel would be your best choice. The integration to Excel is unmatched in Electronic Plan Takeoff compared to Planswift or On-Screen Takeoff. What is quite different in Electronic Plan Takeoff is that training, support, and maintenance are INCLUDED with a purchase, whereas training, support and maintenance are extra for Planswift and On-Screen Takeoff. Moreover, annual support and maintenance for Electronic Plan Takeoff year two and beyond is a low fee per company per year, instead of per license. On-Screen Takeoff by On Center Software, and Planswift charge their annual maintenance and support fees per license (mandatory) which costs the end user more expense annually especially if a customer has more than one license.

Why Do We Need Software Engineering?

To understand the necessity for software engineering, we must pause briefly to look back at the recent history of computing. This history will help us to understand the problems that started to become obvious in the late sixties and early seventies, and the solutions that have led to the creation of the field of software engineering. These problems were referred to by some as “The software Crisis,” so named for the symptoms of the problem. The situation might also been called “The Complexity Barrier,” so named for the primary cause of the problems. Some refer to the software crisis in the past tense. The crisis is far from over, but thanks to the development of many new techniques that are now included under the title of software engineering, we have made and are continuing to make progress.

In the early days of computing the primary concern was with building or acquiring the hardware. Software was almost expected to take care of itself. The consensus held that “hardware” is “hard” to change, while “software” is “soft,” or easy to change. According, most people in the industry carefully planned hardware development but gave considerably less forethought to the software. If the software didn’t work, they believed, it would be easy enough to change it until it did work. In that case, why make the effort to plan?

The cost of software amounted to such a small fraction of the cost of the hardware that no one considered it very important to manage its development. Everyone, however, saw the importance of producing programs that were efficient and ran fast because this saved time on the expensive hardware. People time was assumed to save machine time. Making the people process efficient received little priority.

This approach proved satisfactory in the early days of computing, when the software was simple. However, as computing matured, programs became more complex and projects grew larger whereas programs had since been routinely specified, written, operated, and maintained all by the same person, programs began to be developed by teams of programmers to meet someone else’s expectations.

Individual effort gave way to team effort. Communication and coordination which once went on within the head of one person had to occur between the heads of many persons, making the whole process very much more complicated. As a result, communication, management, planning and documentation became critical.

Consider this analogy: a carpenter might work alone to build a simple house for himself or herself without more than a general concept of a plan. He or she could work things out or make adjustments as the work progressed. That’s how early programs were written. But if the home is more elaborate, or if it is built for someone else, the carpenter has to plan more carefully how the house is to be built. Plans need to be reviewed with the future owner before construction starts. And if the house is to be built by many carpenters, the whole project certainly has to be planned before work starts so that as one carpenter builds one part of the house, another is not building the other side of a different house. Scheduling becomes a key element so that cement contractors pour the basement walls before the carpenters start the framing. As the house becomes more complex and more people’s work has to be coordinated, blueprints and management plans are required.

As programs became more complex, the early methods used to make blueprints (flowcharts) were no longer satisfactory to represent this greater complexity. And thus it became difficult for one person who needed a program written to convey to another person, the programmer, just what was wanted, or for programmers to convey to each other what they were doing. In fact, without better methods of representation it became difficult for even one programmer to keep track of what he or she is doing.

The times required to write programs and their costs began to exceed to all estimates. It was not unusual for systems to cost more than twice what had been estimated and to take weeks, months or years longer than expected to complete. The systems turned over to the client frequently did not work correctly because the money or time had run out before the programs could be made to work as originally intended. Or the program was so complex that every attempt to fix a problem produced more problems than it fixed. As clients finally saw what they were getting, they often changed their minds about what they wanted. At least one very large military software systems project costing several hundred million dollars was abandoned because it could never be made to work properly.

The quality of programs also became a big concern. As computers and their programs were used for more vital tasks, like monitoring life support equipment, program quality took on new meaning. Since we had increased our dependency on computers and in many cases could no longer get along without them, we discovered how important it is that they work correctly.

Making a change within a complex program turned out to be very expensive. Often even to get the program to do something slightly different was so hard that it was easier to throw out the old program and start over. This, of course, was costly. Part of the evolution in the software engineering approach was learning to develop systems that are built well enough the first time so that simple changes can be made easily.

At the same time, hardware was growing ever less expensive. Tubes were replaced by transistors and transistors were replaced by integrated circuits until micro computers costing less than three thousand dollars have become several million dollars. As an indication of how fast change was occurring, the cost of a given amount of computing decreases by one half every two years. Given this realignment, the times and costs to develop the software were no longer so small, compared to the hardware, that they could be ignored.

As the cost of hardware plummeted, software continued to be written by humans, whose wages were rising. The savings from productivity improvements in software development from the use of assemblers, compilers, and data base management systems did not proceed as rapidly as the savings in hardware costs. Indeed, today software costs not only can no longer be ignored, they have become larger than the hardware costs. Some current developments, such as nonprocedural (fourth generation) languages and the use of artificial intelligence (fifth generation), show promise of increasing software development productivity, but we are only beginning to see their potential.

Another problem was that in the past programs were often before it was fully understood what the program needed to do. Once the program had been written, the client began to express dissatisfaction. And if the client is dissatisfied, ultimately the producer, too, was unhappy. As time went by software developers learned to lay out with paper and pencil exactly what they intended to do before starting. Then they could review the plans with the client to see if they met the client’s expectations. It is simpler and less expensive to make changes to this paper-and-pencil version than to make them after the system has been built. Using good planning makes it less likely that changes will have to be made once the program is finished.

Unfortunately, until several years ago no good method of representation existed to describe satisfactorily systems as complex as those that are being developed today. The only good representation of what the product will look like was the finished product itself. Developers could not show clients what they were planning. And clients could not see whether what the software was what they wanted until it was finally built. Then it was too expensive to change.

Again, consider the analogy of building construction. An architect can draw a floor plan. The client can usually gain some understanding of what the architect has planned and give feed back as to whether it is appropriate. Floor plans are reasonably easy for the layperson to understand because most people are familiar with the drawings representing geometrical objects. The architect and the client share common concepts about space and geometry. But the software engineer must represent for the client a system involving logic and information processing. Since they do not already have a language of common concepts, the software engineer must teach a new language to the client before they can communicate.

Moreover, it is important that this language be simple so it can be learned quickly.

Surviving Missing Futon Frame Hardware Nightmares

There seems to be quite a few of us who have owned a futon frame and ended up losing the connecting hardware at one time or another. I myself bought a futon from the retail store I worked in for a number of years back in the early 1990s when futons were all the rage. Maybe you purchased your futon in college, purchased it from a friend or maybe made the purchase for a family room. If you're lucky to live out your life in the same house or apartment there will never be a need to move your futon except except to a different room or location. Obtaining replacement futon frame hardware involves several steps approached in order to locate exactly what you need.

In the first place do not panic just yet. Without the hardware to attach everything back together you're in some serious trouble. However there are ways to obtain what you need. At this point we could explain the many benefits of using a small bag to contain the hardware and attach it to a part of the frame with heavy packing tape so it's easily found. Who am I kidding though? I've moved mine now about three times and each time I ended up missing a bolt, a barrel nut, a nylon roller here and there. Heck, I was lucky I had all the wood components show up at each new move let alone any hardware that happened to make it as well. Besides, is not moving your home stressful enough without having to keep track of a small bag of metal hardware among a sea of ​​furniture, clothing, dishes, toys and appliances?

Pursuing this further we must calmly step back and think for a moment. Yes, we're stressed out and fuming at either our spouse or the moving company for losing the futon hardware but we need to move past that now. To be sure the futon needs our help and we're the only ones who can do it at this point. It's time for us to go through the steps of obtaining replacement hardware and there is a specific order in which we do this to obtain the fastest results. I would suggest the following steps to start tracking down replacement hardware as soon as possible.

First – identify your futon frame.
Having worked retail, it's quite possibly the toughest situation when a customer comes into the store requiring assistance but can not identify the product to the salesperson or service individual when requesting parts. Granted you're going to have to do a little research by pulling your receipt when you bought the futon from the store and identify the model or name of the futon. If you inherited the futon, found it by the side of the road or bought it at a garage sale you're in for a tough road ahead. Fear not however as the internet can be used to help you find the design and attach a name to it for use in tracking down hardware. Be aware that there are dozens of manufacturers out there using different hardware in their frames including many that have since closed their doors. Hopefully the manufacturer of your frame is still around.

Second – speak to the retailer.
Of course if you purchased your futon frame through a local retail store it's time to head down there and see if they can track down the hardware for your frame. Bring your receipt. If you do not have a receipt, then bring an image of the futon frame with you. Hopefully the salesperson or service representative is knowledgeable about the products that they've carried in the past. Best case scenario, they either can provide you with the name of the manufacturer with contact information or have the parts on hand to get you back up and running. Worst case scenario the store you purchased it is out of business or if the store is still around they have no clue about the product anymore.

Third – search online.
Supposing we've hit the worse case scenario it's time to use the web to search for the manufacturer or the name of the style of futon you have. I'd suggest using Google, Bing or Yahoo and use the name adding the word futon to the search. If you were not able to locate a name you're going to have to become a very good spotter and sift through the many images of futon frames till you find one that is very close to what you have. Identify the name of the style and the manufacturer and then proceed to locate the manufacturer of the futon frame.

Fourth – speak to the manufacturer.
Assuming the retailer did not have parts but could identify the manufacturer for you then at least have something to go on. Perhaps you were able to locate your frame style through the search engines. Again, search online using the websites previously discussed using the name of the manufacturer. You'll likely get some online retail stores off of the search. Filter them out visually until you find a link for the manufacturer. Most do have websites, locate a contact phone number or email address and contact them for information on obtaining hardware. If you're unable to locate the manufacturer's website go ahead and contact one of the many futon stores that pop-up in the search results and email them with your issue and ask if they can either sell you hardware or point you in the right direction For finding the manufacturer in hopes of tracking down hardware.

Finally – the last resort.
If you were unable to determine the name of the futon frame or the name of the manufacturer you are indeed in a tight spot. At this point your options are limited to heading down to a hardware store and seeing if you can locate some generic parts that might get you back up and running. The problem will be in the way of connecting bolts and barrel nuts and getting the right lengths if available. I would suggest taking one of the wood arms and a stretcher rail with you to the store. Begin plugging in different bolts and nuts till you find a combination that connects correctly. You'll also need to track down connecting pins, washers and clips for the seat and back section as well as the four nylon rollers that most futon frames use on the back rest. If you're lucky these may still be attached to the backrest deck making your job a bit easier.

In conclusion we've discussed the issues presented with lost futon hardware and how to go about tracking down the hardware you need. Basically identify your frame through a receipt or spotting it online. Visit the retailer store you purchased it from and obtain parts through them if they are still open. If you purchased it privately or inherited the frame track down the manufacturer using a search engine of your choice and speak to them about ordering replacements. If you are not able to locate the manufacturer but have found stores online contact one of them to see if they can sell you hardware. If all else fails visit the local hardware store with your wood futon sections in hand and begin trying bolts and nuts till you find some that work. I sincerely hope you're able to obtain the needed hardware to get your futon frame back up and running. I wish you the best of luck to you and your futon.
