  Development Life Cycle are
• Requirement
• Analysis
• Design
• Coding
• Testing
• Implementation
• Maintenance

4
Requirements

• This is the first stage, where the required
  information are gathered from the customer. 
• The Analyst makes a survey by collecting all the
  available information needed for the system
  elements and allocation of the requirements to
  the software.

5
Analysis

•  In this phase, the system engineer analyze the
  requirement for the proposed system.
• From the available information, the system
  engineer develops a list of use cases and system
  level requirement for the project.

6
Design

• The design is the process of designing exactly
  how the specifications are to be implemented.
• Analysis and design are very important in the
  whole development cycle.

7
Implementation and Testing

• Implementation
• In this section, only developers are involved for
  coding or programming.
• Testing
• Once the coding is done, the analyst go through
  it and test the system for the product
  requirements.

8
Maintenance  Support

• After the release of the product, customers or
  clients give their feedback with respect to the
  product performance and requirements.
