How to say “Politely dismiss someone” professionally

Level 1: Thank you for considering me for this. My current focus is entirely on [Project X], which is due by [Date]. If this new initiative takes precedence, could we discuss reprioritizing my existing commitments to ensure timely delivery of all critical items?

Level 2: I appreciate you thinking of me for this. To ensure I can give it the dedicated attention it warrants, I'd need to pause progress on [Current High-Priority Task]. Could we align on which project offers the highest strategic value at this moment, given current resource allocation?

Level 3: That sounds like an intriguing opportunity, certainly within the scope of *someone's* responsibilities. Based on our last sprint planning session and the RACI matrix for [Project Y], my bandwidth is presently allocated to delivering on our existing, agreed-upon Q3 OKRs. Perhaps we could re-evaluate resource allocation in our next performance review cycle, assuming our current deliverables are considered flexible.

Level 4: I understand this is important. However, taking on this additional task would directly impact the timely completion of [Current Critical Project] and potentially compromise its quality. I need to prioritize my current assignments to meet established deadlines and avoid project delays.

Level 5: Not my problem.

Level 1: Thank you for bringing this idea forward. Our current project scope, as outlined in the Statement of Work, focuses on [Original Scope]. This new request appears to fall outside those parameters. We'd be happy to discuss a separate engagement to address this.

Level 2: We appreciate your continued trust and innovative thinking. While this particular request is not covered by our existing project agreement, it represents an exciting potential enhancement. We can certainly explore adding this functionality as a change order, which would involve a revised proposal and timeline.

Level 3: We always value client feedback, particularly when it deviates significantly from the agreed-upon deliverables documented in Section 3.2 of the signed SOW. To proceed with this novel addition, we'd need to initiate a formal change request process, complete with a re-scoping exercise and a corresponding budgetary adjustment. We anticipate an impact analysis would confirm its strategic value, or lack thereof.

Level 4: This request falls outside the defined scope of our current contract. Implementing it would require a new agreement and an additional budget. We are committed to delivering on our existing commitments as planned, and further requests will be treated as new project proposals.

Level 5: Pay us more.

Level 1: I understand you're looking for assistance with this. Currently, my focus is dedicated to [My Project/Task], which requires my full attention to meet its deadline. Perhaps [Another Team Member/Resource] might have the immediate capacity to help?

Level 2: I appreciate you reaching out. While I'd typically be happy to help, my current bandwidth is fully allocated to my own deliverables. Have you checked the team's shared resources or consulted with [Team Lead] for guidance on the most efficient way to proceed?

Level 3: That's an interesting query, certainly within the purview of [Coworker's Role/Team]. My calendar reflects pre-allocated time for *my* project milestones, as documented in the sprint backlog. Perhaps a quick review of the JIRA tickets assigned to you would clarify the immediate next steps for this particular item?

Level 4: I cannot take on this task. It falls under your responsibilities, and I have my own critical priorities to manage. I recommend you connect with [Team Lead] if you're experiencing difficulties completing your assigned work.

Level 5: Do it yourself.
