Things You Need To Know About Software
Development Life Cycle Phases While approaching
any top software development company, it is
better you brush up your basic knowledge about
Software Development life cycle. This model
describes phases of the software cycle and the
order in which those steps are executed.

• Each step offers deliverables required by the
  next phase in the cycle. Requirements are
  changed into a design. The code is made according
  to the design in the development phase. After
  coding and development, the testing team follows
  the Software Testing Life Cycle which is similar
  to the development cycle.
• To help everyone out, we are discussing the six
  essential phases in every software development
  life cycle.
• Requirement gathering and analysis
• The business requirements from the clients are
  gathered in this phase. It is the main focus of
  the project managers and stakeholders. Analysis
  of the product idea takes place. After
  requirement gathering it analyzed for validation
  and possibility of incorporating it into the
  system of development is been studied. At last, a
  requirement specification document is made to
  serve the purpose of guidelines for the next
  phase of the model.

• Even after the requirements analysis completion,
  the testing team plans the testing planning
  phase.
• Design
• The system and software design are prepared from
  the requirement list made in the first phase. It
  helps in specifying hardware and system needs and
  also define the overall system architecture.
• Also, the testers come up with the test strategy,
  where they brief what to test, how to test.
• Implementation / Coding
• On getting the system design documents, the work
  is categorized into modules/units and real
  coding is started. As the code is produced in
  this stage, it is the main focus phase for the
  developers. And it is considered to be the
  longest phase of the development cycle.
• Testing
• After the code is developed it is tested against
  the requirements to make sure that is solving
  the requirements addressed during the first
  phase. All types of functional testing like
  unit, integration, system and acceptance testing
  are done during this stage.
• Additionally, it is time to move to the
  non-functional testing.
• Deployment
• Well, this the final phase and after successful
  testing the software is delivered to the client
  and deployed either within the company for the
  use.
• As soon as the product is given to the clients
  they are asked to do the beta testing. If any
  changes are needed or if any bugs are caught,
  then they will report it to software developers.
  Once it is bug-free then the final deployment
  will take place.
