As explained above, the project manager is the main factor on how the motivation of the team varies as the project gets done. For example: there was this time that our team was trying to get done a very hard step in order to complete the job. I remember we stayed late throughout the whole week and then we even worked in the weekend. When it was Sunday, the manager told us to take well deserved break and took us to dinner that same day. The food was delicious and the team was able to distress and regenerate energies to start over the following day. On the same way, if the project manager does not stay motivated, this will spread like a virus and the team will be negatively affected by it.
Let me know what you think.
Sincerely,
Roberto Pineda.
