How many phases are in the SDLC?

Question

BlackTom AI · Accepted Answer

The question asks: How many phases are in the SDLC?
Note: The provided data shows an answer choice 'a. 6' but no other options are listed. This means we can't compare multiple choices, but we can discuss the commonly cited counts.
In many traditional SDLC frameworks, there are six distinct phases: planning, requirements gathering/definition, design, development (implementation), testing, and deployment/maintenance. This aligns with the answer choice '6' as a reasonable count in several textbook models.
However, it is important to recognize variation across models: some frameworks present five phases (for example, eliminating a separate maintenance phase or grouping requirements and analysis), while agile variants may describe continuous iteration rather than discrete phases.
Given the data provided, option a. 6 is a defensible count for a classic, six-phase SDLC model, but students should be aware that other valid formulations exist depending on the methodology being taught.
