reflect on team working experience in developing the Project Business Case

recently we submitted as a group a proposal on a project (please see attachments)
the tutor wants three important points to be in the reflection:
-the experience in working with the team and how reflected on me
– MUST be linked to one theory for ex: leadership or management framework (see PowerPoint leadership framework attached)
-key lessons for ex: what weakness found in my self and how to develop in the future. in one of the slides there’s a team role and strengths of each, to say which one I was and talk about another role to develop

we were team of 5 from different backgrounds and countries , different ideas was proposed but I am the one who came up with the idea of the container and everyone agreed to it as it meets the master’s levels. I work for housing association and this is a project we are working on in the company so I asked all the students o send me all questions related to the assignment and I managed to answer / bring information needed once I had the information, work was divided between the others to do the writing and to finalize the assignment.
I agreed from the beginning that my role was only to give them the idea and provide all information needed as I am very busy person I work full time and I have kids and its hard for me to meet, everyone was understanding and happy with what I did.
everyone was motivated and all worked hard.
