SDLC vs STLC: The Main Points of Comparison

SDLC vs STLC The Main Points of Comparison

• The Software Development Life Cycle (SDLC) is a
  process that the teams use to produce quality
  software in the application. The purpose of SDLC
  is to meet customer expectations by a certain
  time by utilizing a cost-effective approach. SDLC
  was designed to handle complex businesses that
  require processing and analyzing data.

• 1. Plan / Gather Requirements
• The first phase plans and gathers the significant
  requirements from different stakeholders. The
  stakeholders can include customers, team members,
  and subject matter experts (SMEs). Generally, the
  information is evaluated to determine what is
  most practical for the software project.
• In addition, the risks and opportunities are
  discussed during this phase. All the requirements
  gathered are used to plan a feasible approach. A
  couple of approaches are
• Technical Approach All the expected services
  that will meet the stated technical scope of work
  (SOW)
• Operational Approach All the steps taken for
  the transition from a softwares current
  condition to an end-result condition

• 2. Design Software
• In the design software phase, the team moves with
  every requirement and creates a design document
  specification (DDS). The main question from the
  DDS perspective answers, How are we actually
  going to build the software?.
• With all the approved requirements, the
  comprehensive software architecture defines
  processes and approaches for each module.
  Individual processes and modules represent the
  data flows and the communication. Usually, the
  DDS designer uses pseudo-code, business rules,
  screenshots, and diagrams (hierarchy, detailed
  logic, entity-relationship, business processes)
  to outline many different functionalities.
• 3. Develop Software
• The development of software begins when the
  developer receives the design document
  specification (DDS). All the components are
  transformed from a high-level overview into the
  source code. The previous planning and
  specifications operate as a guide for
  implementing the required functionality.

• 4. Test Software
• Testing of the software affirms its quality. The
  QA team refers to the system requirements
  document (SRD) or the user stories to verify each
  of the functionality. Therefore, in this phase,
  the goal is to ensure a quality product and
  confirm every functionality working as expected.
• If a bug is discovered, then the QAs reproduce
  the steps, note them, and then assign them to the
  development team. A developer fixes the bugs and
  sends them back to QA. Generally, the QA tester
  who discovered the bug also retests and verifies
  that it no longer exists. Testing is performed by
  the QAs until the software operates according to
  the business requirements and customers
  standards.
• 5. Deploy Software
• In the deployment phase, the team has already
  resolved all the bugs and satisfied the agreed
  specifications. Finally, the software is released
  to the production environment. It is available
  for the market so customers can use the software.
• 6. Maintain Software
• The software maintenance phase is the most vital
  for SDLC. It safeguards the software and
  continues to perform as per the requirements. The
  team gradually transitions from developing and
  testing the software to maintaining the software.
  Based on the different feedback from the
  development team and the end-users/customers, the
  following actions are taken

• Conclusion SDLC STLC Comparison
• SDLC and STLC have phases that extend each other.
  For example, the SDLC encompasses gathering
  requirements and testing software. The STLC
  incorporates analyzing requirements before
  creating a test plan.
• When it comes to setting up the test environment,
  this activity can be carried out in the SDLC or
  STLC. Although essential, the QA team is not
  responsible for constructing the test
  environment. Developers generally set it up so
  testers can start execution. The following is a
  breakdown of each phase for SDLC and STLC
