Final answer:
The final step in the implementation process is to document and communicate the process and results, most likely in the form of a post-implementation review report.
Step-by-step explanation:
The question pertains to the final step in the implementation process of a design or project. In the broader sense, this involves the communication of both the process and the results. When the design process concludes, it is standard practice to document the various steps that have been taken, the results of these steps, and any lessons learned during the process.
This documentation typically takes the form of user manuals, maintenance guides, or a formal report. In this context, the choice that closely aligns with this rationale is the post-implementation review report, whose purpose is to communicate the outcomes after the implementation is complete; hence, the correct answer would be C. the post-implementation review report.
The final step in the implementation process is to write the user manual(s). After the design has been implemented, it is important to provide documentation that guides users in how to use the system or product effectively. User manuals contain step-by-step instructions, troubleshooting tips, and other relevant information to help users understand and navigate the system.
Therefore the correct answer is C. the post-implementation review report.
