Software Development


1. What is software development?

Software development is the process of developing software through successive phases in an orderly way. This process includes not only the actual writing of code but also the preparation of requirements and objectives, the design of what is to be coded, and confirmation that what is developed has met objectives.

Before systems development methods came into being, the development of new systems or products was often carried out by using the experience and intuition of management and technical personnel. However, the complexity of modern systems and computer products long ago made the need clear for some kind of orderly development process.

Typical phases of software development:

1) Identification of required software

2) Analysis of the software requirements

3) Detailed specification of the software requirements
4) Software design
5) Programming
6) Testing
7) Maintenance

In other words:

The process of developing software usually begins with research or a general understanding of what type of software is needed in the marketplace. This may be an entirely new program that addresses an unfulfilled need or a new piece of software in an existing market. As development begins, this research establishes the purpose of the software being developed and the overall goals of the development.

Once those involved in software development have a goal for the program they are working on, they can begin developing the plan for implementing that software. A great deal of work is typically required before any actual code is created, especially for aspects of a program such as the user interface and the basic architecture. Graphic designers, interface developers, programmers, and producers on a large team can all be involved in this stage of development.

Software development then typically moves from these early phases of brainstorming ideas for creating the overall structure of the program to actually writing the code for the software. This implementation typically involves one or more computer programmers, and the source code is created in any number of different applications, programming languages, and other utilities. During and after the code has been created, a great deal of testing is typically involved to ensure the program runs properly and is as free of bugs, glitches, and errors as possible.

In general, the development of commercial software is usually a result of demand in the marketplace, while enterprise software development generally arises from a need or a problem within the enterprise environment.

Ongoing software development may continue even once a program is written, tested, and launched to the general public. Such development may serve to fix errors found after launch or introduce minor improvements and some new features. User feedback can also be utilized to gather information for ways in which the program might be improved in a larger sense. This feedback can then be used to begin software development again on a new version of the program, which can offer features and utilities not found in the previous version.

2. How is software development guided?

The software development process is almost invariably guided by some systematic software development method (SDM). Referred to by a number of terms, including process models, development guidelines and systems development life cycle models (SDLC), software development methods nevertheless generally include the same development phases:

  • The existing system is evaluated and its deficiencies identified, usually through interviewing system users and support personnel.
  • The new system requirements are defined. In particular, the deficiencies in the existing system must be addressed with specific proposals for improvement.
  • The proposed system is designed. Plans are laid out concerning the physical construction, hardware, operating systems, programming, communications, and security issues.
  • The new system is developed. The new components and programs must be obtained and installed. Users of the system must be trained in its use, and all aspects of performance must be tested. If necessary, adjustments must be made at this stage.
  • The system is put into use. This can be done in various ways. The new system can phased in, according to application or location, and the old system gradually replaced. In some cases, it may be more cost-effective to shut down the old system and implement the new system all at once.
  • Once the new system is up and running for awhile, it should be exhaustively evaluated. Maintenance must be kept up rigorously at all times. Users of the system should be kept up-to-date concerning the latest modifications and procedures.

The systems development life cycle model was developed as a structured approach to information system development that guides all the processes involved from an initial feasibility study through to maintenance of the finished application. SDLC models take a variety of approaches to development.
