Key Phases of Software Development Life Cycle

Software development life cycle includes different phases along with orders in which these phases are executed. Most of software companies use their own model for development life cycle; however they have some things in common. Phases of software development provide you a program that can be used in the coming phases of software development life cycle. Some of the basic phases that almost every project includes are:

Requirement Phase

Basic necessities of software are collected in requirement phase. Stake holders and project managers mainly focus on this phase. Meetings are held for specifying the requirements of the business or software. In this phase we usually identify the user of the product. We will also analyze the uses of the system. These are the things that we will collect in this phase of software development. On completion of this phase, we will be in position to identify the requirements of the system, there functions, and also the needs of the user interface for the end user.

Design Phase

After completion of requirement phase, we will be in position to move toward the design phase. In this phase the designer uses different hardware and software tools to produce the complete system design.

Implementation Phase

Once the design phase is completed, implementation phase starts for coding the design. This is the most important and tricky phase of life cycle. It is only the concern of the developers since this is a coding phase. There are lots of tools for the automatic production of code using the data collected in design phase of software development life cycle.

Testing Phase

Once the software implementation comes to an end, testing phase is used to check the product against the requirements defined by the stack holder. One can perform unit testing in order to check the software component individually. There are also some testing techniques for checking overall system functions.

Deployment and Maintenance Phase

Deployment phase comes after testing phase of software development life cycle. In this phase we make software system ready for release. After deployment, it is really necessary to train new users of your software program. Maintenance of product or software to deal with problems takes even more time than software development. Always keep in mind that maintenance cost should not exceed dedicated budget limit; in such cases company will go for developing new system.

Following these basic practices can help you produce a system that is 100% accurate and working according to the requirements of the stack holder. In case of any help, try contacting software houses for your assistance. You will definitely be pleased by the services that software companies offer.
