Create a chart listing all stakeholders in the project. You do know who all potential stakeholders are, don't you? It can't hurt to analyze whether or not there are other stakeholders you haven't considered. Is that other outspoken manager acting the way she is because of her department's stake in your project?
Once you're sure you've listed all potential stakeholders, identify all the interests they have in your project--positive and negative. Consider what changes your project will cause for the stakeholders. What will they have to change? Is your project creating more work for them? Are they losing control or clout somehow? Does it reduce or increase their budget or staff? Are they more or less visible to upper management? If the identified stakeholder is a upper or c-level manager, how will the success or failure of the project impact them?
The most important column in our analysis chart is the importance of the stakeholder to the success of our project. Whether you give them a numeric score or a low, medium, or high type ranking, you need to know which stakeholders are the most critical.
