Software lifecycle:
The SCLC is a series of steps or phases that are followed to create a software project. It is a detailed process that helps you define, develop, maintain and improve that precise pice of software. The steps may change according to the project or the organizations but i'll show the basic SCLD.
The main advantages of using the SCLD is that bye using it you can create an effective, cost-efficient and high quality program.
- Planning helps to look for the quality assurance requirements and identification of the risks associated with the project. It's main goal is to define the various technical approaches that can be followed to implement the project successfully with minimum risks.
- The Analysis is performed with inputs from the customer, the sales department, market surveys and domain experts in the industry. This information is then used to plan the basic project approach and to conduct product feasibility study in the economical, operational, and technical areas.
- Designing the product architecture: SRS is the reference for product architects to come out with the best architecture for the product to be developed based on the requirements specified in SRS. Then it is documented in a Design document specification (DDS). The main stakeholders review the DDS and the best design approach is selected for the product.
- Implementation, this means installing the software on user machines.Software is tested for portability and adaptability and integration related issues are solved during implementation.
- Testing & integration, in this stage refers to the testing only stage of the product where products defects are reported, tracked, fixed and retested, until the product reaches the quality standards defined in the SRS.
- Maintenance: Once the product is tested and ready to be deployed it is released formally in the appropriate market.Then based on the feedback, the product may be released as it is or with suggested enhancements in the targeting market segment. After the product is released in the market, its maintenance is done for the existing customer base.
