Software development is a very tough task which goes through many stages during the whole process. There are many phases in the software development process and it is termed as SDLC(Software Development Life Cycle). To implement successfully software development an organization should adopt some well methodologies that suits the requirements of the project. In the software development process different project require different type of methodologies so it is very important for the software-development service provider to evaluate all the requirement of the project first and after that formulate the overall strategy according to the software-development life cycle.
Most of the software development service providers have their pre defined methods that is implemented at the time of software development process. This pre defined process need a little or slight modifications according to the project requirement but the steps of the development process remains same. The basic stage of the software-development are as below.
Requirement Specifications:- this is the most important phase or step of the software development process. In this stage we are taking all the requirement of the project from the client side in a well documented manner. After receiving all the requirement of the client, organization must start with analyzing the feasibility and all the requirement related to the project. Some questions that must be clarified in this phase are as follows:-
What are the basic requirement of the project.
What the user want in the software.
Is this project is technically feasible or not.
The above question along with many more, must be answered and properly justified before any software developer move further.
Designing:- This phase involves all the development of the outlay for developing the project with all the little details. Project requirement and development streategy for achieving the requirement in a well manner. Designing phase is furthere divided in two categories: system design and component design. As name suggest that system design phase includes designing of the software as a whole where question like how the individual will interact with system or sofware. Second, component design phase deals with the planning for each individual component.
Implementation:- the components are actually created in the implement phase. In this phase developer code all the software in the machine language that is understand by the computer. Programing language like c, C++, java, .Net, PHP etc are used according to the requirement of the project. Source code and data base are created in the implement phase. Accurate designing of the software is essential for a successfully implementation.
Testing:- Testing phase usually starts after all the components are created but in some cases the software development service provider can start the testing phase along with the implementation of the software development for the better results. This method require a more effort and time but the result is very positive i.e. Free from errors and as they deduct and removed as soon as a component is developed.
Installation: all the slots of the of the software are combined together and complet software is installed and executed on a computer system. If all the previous phases have been performed expertly then there will be no problem in the installation phase.
Maintenance: It has been noticed that almost every software needs some changes and modification after it is completed. This may be due to according to the client's requirements, features or change in the business strategy. This requires immediately evaluation and maintenance of the software.
Most of the software development service UK providers follow the above described development methodology for creating softwares. It is the basic methodology of S/W development services. Once the software is completed and delivered successfully, the task of the service provider does not end. A professional S/W development company will offer maintenance services to insure a smooth and well functioning solution to their clients.
