According to the PMBOK Guide, a sprint cycle is a time-boxed iteration of a fixed duration that delivers a potentially releasable product increment. A sprint cycle consists of four events: sprint planning, daily scrum, sprint review, and sprint retrospective. The purpose of a sprint cycle is to create a rhythm of work that allows the team to deliver value to the customer in a predictable and sustainable way.

The PMI Guide to Business Analysis states that one of the roles of a project manager is to manage stakeholder expectations and ensure alignment of project objectives with business needs. The project manager is also responsible for facilitating communication and collaboration among the project team and other stakeholders, as well as resolving conflicts and issues that may arise during the project.

Therefore, if the project sponsor is consistently changing the prioritization of modular work packages, the project manager should set up a meeting with the sponsor to explain the importance of keeping a strict sprint cycle. The project manager should:

Clarify the project scope and objectives, and how they are aligned with the business needs and the sponsor’s vision

Explain the benefits of a sprint cycle, such as delivering value faster, improving quality, increasing feedback, and reducing risk

Highlight the challenges and risks of changing the scope frequently, such as disrupting the team’s workflow, reducing their morale and motivation, increasing technical debt, and compromising the quality and usability of the product

Negotiate with the sponsor to establish a clear and stable prioritization criteria for the work packages, and agree on a process for managing changes and requests

Involve the project team and the product owner in the prioritization and planning process, and ensure their input and feedback are considered and valued

Document and communicate the agreed scope, priorities, and changes to all the stakeholders, and monitor and control the project performance and progress

By setting up a meeting with the sponsor to explain the importance of keeping a strict sprint cycle, the project manager can:

Build trust and rapport with the sponsor, and demonstrate their understanding and respect for the sponsor’s perspective and needs

Educate the sponsor about the agile principles and practices, and how they can help achieve the project goals and deliver value to the customer

Influence the sponsor to adopt a more collaborative and flexible approach to the project, and to respect the team’s autonomy and expertise

Minimize the impact of scope changes on the project schedule, budget, quality, and risk

Enhance the team’s morale and teamwork, and foster a positive and supportive work environment
