Stages of Software Development Cycle

SDLC (Software Development Life Cycle) is a series of six main phases through which any software system passes. The purpose of SDLC is to create a high-quality program which will suit all customer`s needs. In this article we are going to discuss in general the stages of life cycle of software development.

    The main stages are:

  1. Planning
  2. Analysis
  3. Design
  4. Development & Implementation
  5. Testing
  6. Installation & Maintenance

The planning phase is the most critical step in creating a successful system. In case you do not have an ideal plan with calculations of the strong and weak sides of the project, development of software is absolutely bare of context. During this stage you make the following steps: 1) gather requirements; 2) identify problems and objectives; 3) explore alternative decisions through meeting with customers and staff members; 4) learn how to maintain a competitive edge regardless your competitors.

At this step, it is necessary to define and document the requirements of the end user of the system — what are his/her expectations and how to implement them. In addition to this, a feasibility and profitability studies are conducted for the project to ensure whether the project is worthwhile. Moreover, it is important to keep in touch with your customers frequently to ensure that you have an excellent understanding of the final product and its functions.

This phase begins as soon as a good understanding of customer`s requirements is achieved. This stage presupposes an advanced and detailed design, taking into account all the functional and technical requirements.

Development & Implementation
This phase follows a clear vision of system requirements and specifications. This is the actual system development process, when the system design is already complete. In the life cycle of developing a system, code is written here. A lot of programmers work for coding and create the desired software.

Once coding is complete, the software undergoes tha stage of testing. Before the launch, the product is in need of verification which is inclusive of software testing and debugging. As soon as testers ensured that software is without errors, it goes to the next stage.

Installation & Maintenance
Finally, software is passed to the clients to install in their devices. Then periodic system technical support is provided to ensure that the system is not out of date. It also updates certain components to ensure that the system meets the required standards and the latest technology.

These are the main stages of Software Development Life Cycle which are commonly followed by the majority of IT companies to create a high-quality program.
