Platform as a Service (PaaS) is designed to accelerate software delivery by providing a managed platform that typically includes the operating system layer, runtime, middleware, databases, and developer tooling—so teams can focus on building the service rather than provisioning and maintaining infrastructure and OS components. This directly supports the goal of speeding development and delivery while integrating closely with OS-level services provided by the platform (e.g., runtime services, identity, logging, scaling, patching). CompTIA Project+ includes understanding cloud models as part of IT concepts that affect project delivery choices.

By comparison, SaaS is a finished application you consume (not a development platform). IaaS provides raw compute/storage/networking; you still manage the OS and much of the stack, which is slower for development acceleration. DaaS generally refers to delivering desktops or data services depending on context, but it is not the standard model for speeding application development via an integrated platform stack.

Therefore, PaaS best matches the scenario: it reduces setup/maintenance work, standardizes environments, and helps teams deliver software faster and more reliably.

Notifying the CCB that an approved change “failed” is consistent with logging and escalating an issue/incident arising from change implementation. In CompTIA Project+ objectives, the change control process includes not only approval and implementation, but also validating the change implementation and communicating change deployment. If validation shows the change did not achieve the expected outcome, that result must be documented and escalated through the same governance path (often the CCB) so the project can decide whether to roll back, revise, or raise a new change request.

CompTIA also separates risk management (responses to potential future events) from issue management (handling problems that have already occurred), including issue tracking, escalation path, ownership, and a resolution plan, and it highlights “connections between issues and changes.” A failed implemented change is an issue now, so an incident report (documenting what happened, impact, and next steps) best matches the control process being followed.

“Scope creep” is unauthorized scope growth, “risk response” is for anticipated risks, and “recovery plan” could be a next action, but the process described is the reporting/documentation and escalation of the incident.

During the project closure phase in the waterfall methodology, it is crucial to validate the deliverables to ensure that all project requirements have been met and the project outputs are complete and satisfactory. Additionally, reconciling the project budget is performed to ensure all financial records are accurate and reflect the actual project costs, which is essential for the formal closing of the project.

Regression testing is a type of testing that is done on an existing system to ensure that the previous functionality still works after a change has been made. Regression testing is a process of retesting or verifying that a software system or application still performs as expected after it has been modified or updated with new features, bug fixes, patches, etc. Regression testing can help to detect any errors or defects that may have been introduced by the change and ensure that no functionality has been broken or degraded.
