Same question on ITPEC: Apr 2024 Q49

Among the descriptions A through D concerning software installation, which of the following lists all and only the appropriate descriptions?

A:In a new development, installation is performed without delay by the deadline without the creation of an implementation plan.B:After software installation is performed, an implementation plan and an implementation report must be created promptly and agreement obtained.C:When software is developed in-house by a company, the scope of impact is internal, so installation is performed after the creation of an implementation plan, and agreement on the implementation plan is obtained after implementation.D:When a function is to be added to software in production system, an implementation plan is created for the software with the added function, agreement is obtained, and software installation is performed.

Explanation

D only — software is installed following an implementation plan agreed beforehand, including when a function is added to a production system.

Software installation moves developed or changed software into the production environment. Before it starts, an implementation plan is created (schedule, procedure, people, checks after installation, and how to fall back if it fails), and the parties concerned, such as the users and the operations side, agree to it. The installation then follows the plan, and a report on the result comes afterwards.

  • •A: a deadline does not remove the need for a plan; installing without one leaves no agreed procedure or fallback
  • •B: a plan written after the installation cannot guide it; only the report comes afterwards
  • •C: in-house software still affects the company's users and operations, so agreement is needed before installation, not after
  • •D: plan, agreement, then installation, in the right order

Answer (d)

Why not others:

  • •(a) A, C — both install without a plan agreed in advance, and D is missing
  • •(b) B, C, D and (c) B, D — include B, which creates the plan and obtains agreement only after installing

Key rule: Every installation into production, new or changed, runs plan, agree, install, report; an agreement obtained after the fact controls nothing.
