Introduction:

In the present Information Technology (IT) industry, a number of both In-house and Offshore Software Projects have a tendency to get scrapped before its completion. Failure Analysis refers to various Management Indicators. A brief description of developing a Model and performing quantitative analysis for successful completions of software projects are discussed here. When the estimated budget for the project is known, this model calculates the number of skilled Software Professionals required, so that all constraints are satisfied.

Software Project Phase :

The Model uses the below tasks as its basic assumption.

1. Identify the Prevailing Market rate for Skilled IT Professionals

2. Budget amount sanctioned

3. Implementation & Support during Warranty Period

Model Assumptions:

This Mathematical model assumes that data is available for these controllable variables.

Controllable Variables:

a) Wage rates per hour for:

TEAM LEADER = $ Wtl

SYSTEM ANALYST = $ Wsa

DEVELOPER = $ Wdl

TESTER = $ Wts

b) Budget sanctioned for the Project = $ Pb

c) Sanctioned Budget is $ Pb = ( Pi + Pa + Pr)

where Pi is the Initial amount used primarily for System Development = Ki * Pb ,

Pa is the budget amount used for redesign/redevelop the System = Ka * Pb ,

Pr is the budget amount used for System Implementation = Kr * Pb ,

where Ki , Ka , Kr are the percentage allocated from the sanctioned amount

At the end, this Model solves for the total number of skilled professionals that the IT Department can recruit to get the project completed within the specified duration and without exceeding the sanctioned budget.

Number of skilled professionals :

TEAM LEADER = Ntl

SYSTEM ANALYST = Nsa

DEVELOPER = Ndl

TESTER = Nts

Total number of Skilled Professionals : TSP = (Ntl + Nsa + Ndl + Nts)

Data Calculated:

Uncontrollable Variables:

A Project Manager with diverse experience in Software Programming and System Analysis can assign suitable values to these variables.

Ratio between Redesign and Initial phases:

SYSTEM DESIGN = Ksd

DOCUMENTATION = Kdp

SYSTEM DEVELOPMENT = Kdv

SYSTEM TESTING = Kst

Estimated time to perform the Job in Hours: (initial expectations)

SYSTEM DESIGN = Tsd

DOCUMENTATION = Tdp

SYSTEM DEVELOPMENT = Tdv

SYSTEM TESTING = Tst

Restart time (repeated process a maximum of THREE times ):

SYSTEM DESIGN = Rsd = Ksd * Tsd

DOCUMENTATION = Rdp = Kdp * Tdp

SYSTEM DEVELOPMENT = Rdv = Kdv * Tdv

SYSTEM TESTING = Rst = Kst * Tst

Estimated time to Implement = Tit

Estimated time to Implement = Twp

Project Costs:

Initial Stage:

Initial cost of SYSTEM DESIGN (Isd) = Tsd * (Ntl * Wtl + Nsa * Wsa)

Initial cost of DOCUMENTATION (Idp) = Tdp * (Ntl * Wtl + Nsa * Wsa)

Initial cost of SYSTEM DEVELOPMENT (Idv) = Tdv * (Ndl * Wdl + Nsa * Wsa)

Initial cost of SYSTEM TESTING (Ist) = Tst * (Ndl * Wdl + Nts * Wts + Nsa + Wsa)

Testing/Redesign Stage:

The probability to find a “Bug” in source code or even in the system design by the testers exists. Once it’s identified, depending on the type of the Bug, the systems analyst will either redesign the system or let the developers rectify the problem.The System Testers perform the testing again. Though it’s an endless process, it’s assumed that this process doesn’t repeat more than THREE times.

Cost of SYSTEM DESIGN (Csd) = 3 * Rsd * (Ntl * Wtl + Nsa * Wsa)

Cost of DOCUMENTATION (Cdp) = 3 * Rdp * (Ntl * Wtl + Nsa * Wsa)

Cost of SYSTEM DEVELOPMENT (Cdv) = 3 * Rdv * (Ndl * Wdl + Nsa * Wsa)

Cost of SYSTEM TESTING (Cst) = 3 * Rst * (Ndl * Wdl + Nts * Wts + Nsa * Wsa)

After the development is completed , let the application is ready for implementation. During the Warranty period, Redesign, Rewrite, Retest ,and implementations are to be considered. This additional expenditure also need to be considered while the estimating the budget.

During the Implementation process and Warranty period, the cost anticipated will be:

Cost for Implementation & Warranty period coverage Cr = (Tit + Twp) * (Ndl * Wdl + Ntl * Wtl + Nsa * Wsa)

Linear Equation :

The linear equation used for this Model is:

Pi = ( Isd + Idp + Idv + Ist )

Pa = ( Csd + Cdp + Cdv + Cst )

Pr = ( Cr )

Model Constraints:

Constraint assumed is that More time is required to test thoroughly before implementing ;

Tst >= (Tsd + Tdp + Tdv ) and Rst > Tst andand Nsa > Ntl and Ndl > Nsa and Ndl > Nts and and Ka > ( K i + Kr )

(Ndl + Nts ) > (Ntl + Nsa )

and Rst >= (Rsd + Rdp + Rdv )

Conclusion:

Although it is a basic approach to design the model, every effort is made to consider all the possible phases in a Software Development Life Cycle, that were gained from real-time experience. Using Advanced Regression Analysis, Sampling Techniques, and Chaos Dynamics, this model can be made more reliable.

Registry Cleaners are effective in detecting and repairing all forms of registry errors; they clean out useless junk files, improve system stability and increase PC Performance. Registry cleaners help remove the rubbish that builds up in your computer’s registry. Most of these problems are caused by deleting and creating files, installing and removing programs, and surfing online. Registry cleaners are fun! In my experience the only registry entries that effect Windows overall speed are entries that involve autorun / autostart programs.

Computer

The computer’s registry is the nerve center of a PC. It stores all the hardware, software and user settings, which keeps growing when you use Windows.

Computer crashes, freezes and overall slow operations can make even the calmest of people pull hair out from its roots. When these issues arise, there is a very good chance that the fix is easier than many think.

Registry cleaners

Registry cleaner’s offer lots of different things, but in the end, they all do the same thing. They clean up any loose and unneeded files that hang around from botched installations or uninstallations as well as any spy ware you may have downloaded while surfing the net. Registry cleaners work by removing outdated and incorrect entries from the Windows registry, the DOS’s repository for all system settings. It dates back to Windows 3.11, and with each new version of Windows, it has grown in complexity. Registry cleaners eliminate a major problem inflicted on PC today: Windows registry errors. The problem is many of us haven’t a clue what one is or how to deal with the aftermath.

Registry Cleaners are effective in detecting and repairing all forms of registry errors; they clean out useless junk files, improve system stability and increase PC Performance. Registry cleaners help remove the rubbish that builds up in your computer’s registry. Most of these problems are caused by deleting and creating files, installing and removing programs, and surfing online. Registry cleaners are fun! In my experience the only registry entries that effect Windows overall speed are entries that involve autorun/autostart programs.

Registry cleaners are usually based on one of two scanning techniques? Smart and Safe and Bulk and Deep. The registry cleaners using the Smart and Safe technique take utmost care to report only genuine errors. Registry cleaners can be part of a package of system utilities or a stand-alone program. Registry cleaners are great for improving the overall performance and speed of your computer by removing the temporary files that tend to clutter the registry. This is a common and known issue in Windows computers.

Is your PC slow to boot up? Does Windows XP ‘hang’ whilst working on an important document? You made the investment in your PC so that you could enjoy the benefits of a fast, easy machine that would make your life easier and more enjoyable. Unfortunately, after continued use, all PC suffer the effects of a corrupt and ineffective Windows Registry, causing error messages to appear, slow loading, and system crashes.

Running of background processes and programs will slow down the pc performance. Most of the time, these background activities occur without your knowledge and it is always the main cause for PC hanging. Run a spyware/adware scan: Spy wares, ad wares and viruses are notoriously known to make your PC slow down to a crawl (as if they didn’t already cause much harm). Use Lavasoft’s Ad aware and AVG’s Free Antivirus to eliminate those nasties and you will notice an improvement in system stability and performance. Runtime errors occur when an application is in use and encounters a problem that was not expected nor were caught by the testers / developers of that application. These errors are often followed by the user saying “What the???? Because in most cases, the application that has encountered the error doesn’t even know what to do.

Spy ware

Spy ware applications are typically bundled as a hidden component of freeware or shareware programs the can be downloaded from the internet. A common way to become a victim of spy ware is to download popular peer-to-peer file sharing programs. Spy ware in particular will cause your surfing to slow down more and more. Anti-virus and anti-spy ware software is essential in getting back your normal surf speed and of course in removing unwanted malicious software.

Defragging

Defragging the drive is an easy task, and Windows XP provides a handy tool for doing it. The tool will first analyze your drive to determine if defragging would be beneficial. Then Defragging checks the data for critical errors like cross-linking and reports the same to the user. Moreover, running defrag at regular intervals also gives you a fairly good idea about the health of your hard disk. Running the defrag on your hard drive arranges the files so that they can all reside on your hard drive in one piece. The fewer pieces the computer has to look for to load a file the faster things will work.

Dot Net Inventory System combines the power of the dot net platform into inventory control software, providing the most flexible, powerful and highly customization solution for both developer and end user. When we talk about Inventory, the database system plays most important part, from storing data to processing, it all down to the database to produce updated reporting. A good inventory control system consists of 4 main components…

Component #1 - Scalability.

From the software interface to database storage, all must be scalable to support a larger amount of items and transaction. Multiple end user interface ensure suitability on different application, the dot net platform is extremely portable and supporting multiple different interface, from web to windows and Silverlight cross platform presentation layer.

Component #2 - Extensible.

Source code based software will provide the highest extensibility, developer can easily modify, enhance and extend feature and functionality to the system. Good source code design must be plug-able, easy to integrate and RAD in nature. RAD means Rapid Application Development; The source code itself must be created in RAD tools to ease the future enhancement.

Component #3 - Real-time performance.

No matter if the system process data in real-time or batch, it must be able to provide “real-time” performance, fast and accurate. This highly dependent on the stored procedure coding in the server site processing. If the software cannot handle a large volume processing in time, it will be a problem for another Integrated system, such as Point of Sales or Warehouse control system, delay processing will also delay reporting.

Component #4 - Remote Access.

Every business software today must equip with remote access, that’s why web based application has become many software vendor’s priority, they all need to provide the information anywhere, anytime! For the security reason, some people might prefer powerful Windows client that connect through Internet for access the information.

Always use these 4 components as a guide to select the proper software for your company. Company with the development team should always consider the source code based Inventory system, and only source code based Inventory can provide the highest flexibility to a development team.

The advent of the Internet, in some respects, made the job of parenting a little harder. We want our kids to experience the vast wealth of knowledge available online and communicate with their friends online (frees up the telephone). Unfortunately, it also exposes our kids to inappropriate material, obscene pop-up ads, and even sexual perverts.
In fact, research indicates that 1 in 5 kids aged 10 to 17 have received a sexual solicitation over the Internet. This is definitely not something any parent/guardian wants to hear, but is forced to face.

In order to fulfill the responsibility of securing your kids online, you as a parent/guardian must master the basic principles of the computer. Only then can you guide them and teach them the do’s and don’ts of the internet. Teach them to use the internet safely, encourage them to share their experiences with you and enjoy the internet along with them. Kids should basically show respect to others online, just as you teach kids rules of good behavior when they move in society.

Nevertheless, there is technology available, which can help to protect your kids from any content that is not appropriate for them. So you can use software to block this inappropriate content. Microsoft software, for example, has different types of software for this. ‘Windows Vista Parental Controls’ helps parents to manage, monitor and administer the use of computer by the kids. Another software called ‘Windows Live OneCare Family Security’ filters the information, so that even the child’s searches can be blocked, if they are inappropriate for its age. Even DVD movies and games can be restricted by a software called Xbox parental controls.

Besides, you can increase your security and privacy by making your kids limited users in your
Administrative Account, by giving them Limited User accounts. This restricts the kids to change system settings, install any new software which includes chat programs, games, etc. Online security of your child can also be done through your web browser. All that you have to do is to adjust your web browser security settings and web sites can then be assigned security levels.

Also you can keep track of the websites that the kids are surfing. If you check out the History List in Internet Explorer, it is possible to see where the kids have been surfing. Even email addresses, correspondence and downloaded files can be viewed by you.

Kids should be taught to be careful during chats and instant messaging sessions and not to give
away personal identity, names, addresses and telephone numbers. This is how they become victims to impostors and predators.

Make your kids aware of the hazards of the internet and teach them how they can come out of difficult situations. Having talks and discussions with kids about the risks is important, and as parents/guardians one should set certain limits. If the security of the kids is taken care of, only then can internet be a source of fun and information, without which the environment is incomplete.

For many years, it has been feasible to connect two or more computers together using cables, so that computer users can swap and store files share printers,share an Internet connection or other general resources.

Wireless networking is a technology that enables the wiring that connects each computer to the network to be replaced by a coded wireless signal, commonly known as a wireless router. When fitted with a wireless network card, a computer can swap data with other equally equipped computers nearby without the need to be plugged in,thus forming a wireless network.

Wireless networks can be easily put together with only limited knowledge of computers and networking. Most wireless routers come with their own
software that will make them “plug and play”,so for many users it has simply been a matter of install and go. However, this misleading ease of use hides a number of pitfalls to do with contradictory standards, physical limitations with wireless signals,and security issues. These pitfalls can make setting up a wireless router a nightmare if the issues are not well thought-out before the wireless router is purchased.

Like a wired network, a wireless network is impartial to the operating systems used by the computers on the network. Whether you are a PC, Mac or a Linux user you will be able to connect to a wireless router if you have installed a suitable wireless card in your computer or laptop.

In the last few years, low cost wireless components have created a number of ways of linking computers together wirelessly. These networks are growing in popularity because they offer low purchase costs, almost no installation costs and they allow wireless equipped computers to be freely moved around the room, the building or even outside. The greatest advantage seen by most is the loss of all the cables connecting the computer

There are 4 steps to creating a wireless network:

1.Choose your wireless router

2.Connect your wireless router

3.Configure your wireless router

4.Connect your computers

It’s called a router for the simple reason that signals are being routed back and forth. The computers can be connected to the router either with a wire (called an Ethernet Cable), or without wires Most wireless routers have at least one antenna. Data from the Internet will travel through the router and then those antennas. They are then broadcast to the Wireless Adaptor on your computer or laptop. (And any other wireless adapter in range - whether its yours or not).

Confused with all the different wireless routers available? Not sure which is the best one to choose. Save yourself hours of research. The best wireless routers on the market are reviewed HERE

Antispyware programs have become very popular these days. This is because malware, along with its friends spyware and Adware have become so prevalent. It is impossible to avoid these odious things if you ever surf the Internet. These types of parasites are a growing concern to say the least. In 2007, there were more new types of malware developed than all that was developed in all the years put together before the year 2007.

Spyware is a type of malware. We often think of malware as just another type of spyware along with Adware. This is not true. Spyware and Adware are types of malware. So are Trojans, worms and keyloggers. There are other types of malware as well. It seems these harmful parasites are becoming more and more malicious every day.

Spyware and Adware Used to be Relatively Harmless

There was a time when spyware and Adware were simple programs. Their quest was to find out what type of a buyer you were and report back to the people who use the spyware so they could get a better idea how to sell you stuff. Though it is true this is still a function of spyware and Adware it has unfortunately, become more complicated and devious.

Viruses used to be the most serious threat a computer owner faced. Still, a virus is an executable file, which cannot be set loose in the computer until the operator does something. For instance, most viruses come as an e-mail attachment. When the computer operator opens the attachment, the virus is set free to do evil to the computer. Of course, the way to avoid getting a virus is to not open e-mail attachments.

Trojans

This is all well and good. However, Trojans are types of programs that do things the computer operator finds productive or fun. Trojans could be a game or some other type of computer software. The problem is as the computer operator uses this software he is setting loose a virus in his computer. So much for the simple rule, “never open e-mail attachments.”

These Trojans and viruses can be used just as a way to disable your computer and ruin your hard drive. The possibility can’t be overlooked that cyber-terrorist could use Trojans in this way. The way they are being used most these days however is to discover things about the computer owner, like maybe very personal information. Can you say online banking?

Keyloggers

Keyloggers are also used to gather personal information. As the name implies a keylogger will log every stroke on your keyboard. Therefore, since other spyware and Adware associated with the keylogger will know what site you’re on, it will find out what password you used to get into the site. With a little bit of imagination, you could figure out a lot of underhanded ways a keylogger could be doing you harm.

As you can see, it is very important to scan for malware very often. It is also important you use an Antispyware program that scans for all types of parasites, including keyloggers and Trojans. It is equally important the program updates its definitions frequently. This is because the malware program writers are fast at work trying to get ahead of the Antispyware programs that are trying to stop them.

Where all this is a leading no one can say for sure. We do know that malware, with all its components spyware; Adware, Trojans and keyloggers are becoming more and more sophisticated daily. If we let these infections get hold of our computer, it could be detrimental to our computer’s health. However, even more frightening is the fact it could be devastating to our financial health.

We have all asked the question of where to download spyware remover from. There are an amazing number of websites nowadays, and it can be quite a daunting task to try and find the best one.

Spyware is a devilish program that wants to install itself onto your PC without your knowledge or consent. Then it wants to hide inside of it, and collect every move that you make.

It will stop at nothing to steal your personal info, and will record things such as:

-What websites you go to online

-what programs you run on your computer

-Everything that you type on the keyboard

-It will monitor your credit card numbers and bank account numbers if you shop online.

-It will even steal data that is hidden inside of your computer.

Once you are infected with spyware, the makers of these programs can take control of your computer. They can then use it to do evil things such as:

-Send Millions of spam emails with your ip address

-Hack into your computer and change your homepage

-Steal any and all important files you might have

-Hack into goverment agencies and banks

In almost all of the cases above, they would be using your ip address. Guess who would then get blamed for everything. That’s right. YOU. It is no wonder that every body and their grandma want to know where to download spyware removers.

But don’t go downloading just any spyware remover. Most of these programs are actually created by the same makers as the rogue programs. They can then infect your system even further, and make it impossible to do anything about it. This is even more true for the so called “free” programs that come bundled with heaps of other malicious files and programs.
