Steps In The Development Process

Steps In The Development Process

For each step, we will discuss 3 things:


  • who
  • why
  • what

Steps In The Development Process

  • Gather and analyze requirements
  • Document requirements
  • Create UI mockups and prototypes
  • Create PBIs (and bugs if existing software)
  • Have project planning meeting with developers.
  • Create high level software architecture. (link)
  • Create low level detailed code design.
  • Write tasks and estimate hours for each PBI and bug.
  • Have sprint kick-off meeting.

Steps In The Development Process (Cont'd)

  • Software construction.
  • Daily scrum meetings.
  • Write unit tests.
  • Do peer code reviews.
  • Deploy to Dev/QA environment for QA.
  • QA will test in Dev/QA environment.
  • Fix bugs.
  • Demo software internally.
  • Deploy to staging environment for final QA.

Steps In The Development Process (Cont'd)

  • QA will test again in staging environment.
  • Fix bugs.

The result of a good process lived out:


SST is a well-oiled machine when it comes to cranking out software.


This is NOT the norm!
