Everything around us rapidly change in this 21st century & now train, bus, car, post office, banking & attendance system etc are all computerized. Since it work according pre define functions, give result accurate, never tired & more reliable, people trust on these automated systems.
Software is the soul of computerized system. A computerized system work quite soft & easily but a big mind of a software engineer works behind it. Software development is a long process & is developed step by step. Software engineers develop software by taking into account the following aspects of software:-
Planning of the project – This is the 1st step of the project in developing software by a client. It helps to study what problems may occur when developing this project.
Study of feasibility – This step checks if the project is feasible or not. Project cost cover by client or not along with check estimate the time of the project & if this project may develop in the ensured field or not.
Design of the system – This is the most critical step of project development. Where the data is stored, from where does the data come & go, how are the data & information displayed, etc step cover in this field.
Coding – Coding works are performed by the programmer & is written according to the system design.
Implementation – Big software is developed by a number of small software (program). Working of each program is checked in this step.
Software Integration – It includes all the programs integrating & developing software.
Software testing – This step is important for a bug free & efficient application. In this phase developed software is tested to assure that it works according to the client’s requirement. To make a foolproof application lot of time is dedicated in this step & this step insures the good character of software.
Installation -In this step software is handed to the client & all cost of software development is received by the client & the software is installed in client’s computer.
Maintenance – It’s a tedious work because person who has written the code of the software is not available all the time.
Thus software development is not an easy task. When client want to develop software he/she notice software Development Company’s service history. The software should be complete within time, complete within estimate cost & fulfill all requirements of the client. Rather than spending billions of dollars every year on developing their own software applications a company should put it to better use to improve the core business of the company.
The typical software development cycle starts with a base product that is developed & sold, if external or delivered to a client, if internal. If the base product lacks in functionality, modification adding to the cost of development must be done. The implementation & integration phase starts after these modifications are completed. This phase has high cost associated with customization. Finally annual maintenance & service fees are charged but do not include future upgrades. Clients are frequently less happy with the results and the software development is often unaware that the client is not happy until the next cycle & it’s too late & too expensive to address the problems. Thus the software developed for a client completely lags behind the client’s actual needs.
Over the past few decades computers have automated most industries. If there is an industry that should be automated it’s the software industry. Writing software is still a manual process involving monotonous & repetitive tasks. Techniques such code reuses & code generation has been developed over the years to reduce the work load. Developers are inherently resistant to change & since developers are reluctant to use tools & technique in own their development they become their own worst enemy.
A tool is needed that would take care of the repetitive & monotonous task. These laborious tasks are where a computer excels. This tool is ready for those who can accept giving up total development control & let the computer do what it was invented for!!!!!!!!!!
