Which of the following is MOST important to ensure successful implementation when an organization decides to purchase software from available products on the market?

Question

Options

• BPost-implementation review
• CSupport and maintenance contract
• DSoftware escrow

• A

• B
  3% (1)
• C
  3% (1)
• D
  3% (1)

Explanation

Requirements definition (A) is the foundation of any successful software purchase - without clearly defined requirements, an organization cannot evaluate whether a product actually meets its needs, leading to costly mismatches, rework, or failed implementations.

Why the distractors fall short:

• B (Post-implementation review) happens after the fact and cannot fix a poor product selection - it's useful for lessons learned, not for ensuring success upfront.
• C (Support and maintenance contract) is important for ongoing operations but is irrelevant if the wrong software was selected in the first place.
• D (Software escrow) protects against vendor failure by holding source code in trust - a risk mitigation measure, not a success factor for implementation.

Memory tip: Think "measure twice, cut once" - requirements definition is the measuring step. Everything else (contracts, reviews, escrow) only matters if you picked the right tool for the job. On the exam, questions about ensuring successful implementation almost always point back to the requirements phase.
