How do you get your team excited and motivated to take on a massive new project? Aside from sharing details, goals and steps, do you have a strategy for helping your team feel truly engaged?

For any project, there is always a vision and a roadmap. If the team is aligned with the vision, there is a sense of excitement towards achieving the results.

Data driven strategy always works. The magic is in the details. 

Another critical aspect is the user persona for whom the project is getting built and how the team's effort will impact the life of user whether its a B2C consumer or B2B or infact an internal user. 

Firstly we include the team to build the charter for the project- get them excited
For massive projects you may have many team members across sites , we start off by having a kickoff by our GM . Each site may have planning sessions and some joint sessions over the web. People getting to know each other across the sites/ remote, is very important for this large team to feel connected.

Setup Milestones - Have demoes ,celebrate each milestone , major achievements by the team. We usually have senior leadership join in a small team event - including even remote employees if possible.
Create a scoreboard that shows a burn up of major tasks for the project so team can see the progress to goal.
