According to the PMBOKGuide, a hybrid project is a project that uses a combination of predictive and adaptive (or agile) approaches to deliver the project objectives1. A hybrid project requires the project manager to balance the different needs and expectations of the stakeholders, as well as the different methods and practices of the project teams2.
In this scenario, the project manager is facing a challenge of managing a hybrid project, where the self-organizing teams are using an agile approach, but the steering committee is expecting a predictive approach. The project manager should apply the agile principle of delivering working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale3. This means that the project manager should suggest to the teams to limit the scope of work per iteration (or sprint) so that they can deliver more reliably and demonstrate value to the steering committee. This can also help improve the team's morale, as they can see their progress and achievements more clearly.
Option A is not the best answer because it does not address the root cause of why the teams are late in delivering their demos. Emphasizing the importance of deadlines and value may increase the pressure and stress on the teams, rather than motivate them. Option B is not the best answer because it does not provide a specific action or solution to the problem. Requesting to coach the team may be helpful, but it does not guarantee that the team will improve their performance or deliver on time. Option C is not the best answer because it does not align with the agile value of responding to change over following a plan4. Updating the project schedule with a buffer may create a false sense of security and encourage the team to procrastinate or delay their work further.
