Software Life Cycle Has 6 Stages
Many people do not realize that there is a software life cycle for programs. There are actually six stages to the software life cycle: design, coding, code testing, system testing, release and distribution. Each of these stages of the software life cycle requires different tasks.
Stage One: Design
In order for there to be a new software product there has to be an initial design. The design stage first determines the goal of the software. What will are the uses? Who will use the program? Additionally, the changes that will need to be made to the system to utilize the software and the basic structure of the software are determined at this stage of the soft ware life cycle.
There is a document generated that will cover all the various aspects of the design of the software. Issues to be covered in the document include the functionality of the software and the implementation of the software, along with other technical issues to implement the software and their solutions.
Stage Two: Coding The second stage of the software life cycle is the actual building or coding of the software. Once all the design issues are sorted the technical aspect of writing out the software is implemented. The building of the software goes through many different steps depending on the type of software and its over functionality and purpose. Often several developers will work on the software at this stage of cycle. Stage Three: Code Testing The third stage of the software life cycle is testing the actual written code or software itself. This is done within the actual software. Stage three and stage two works together to make sure that there are no technical issues that arise or incompatibilities within the actual software. This is an important part of the software life cycle because if there are internal issues with the software the entire thing will not work properly for future stages. Stage Four: External Testing The fourth stage of the software life cycle is the external testing. The software is completely developed at this point in the software life cycle. The entire system is put together and implemented. Next, the system is tested with the software and any problems are then detected and addressed. It is during this stage that many software programs are in beta stages and there is also the use of software change control systems and configuration management systems. Stage Five: Release The fifth stage of the software life cycle is the actual release. Once all the other stages have been completely finished, the software is now ready for official release. This means that others can use the software without any worries or concerns. If the software is a modification of an earlier version, there will typically be a new release number associated with it. Otherwise the standard release numbers are just the actual year that the software was developed. Stage Six: Distribution The final stage of the software life cycle is the distribution. The software is distributed to product manufacturers and marketers with all the specifications. At this stage it is no longer in the developer's hands and is ready to place on the market or to distribute privately within an organization.
