# How Is The Transformation Done?
> Small big top down
An engagement model describes how a team interacts with an organisation, client or internal group.
The engagement model aims to distribute the best and align the team with the improvement team to create a long-lasting relationship.
The engagement model is based on people and outcomes, including a simplified framework of tasks, roles, and collateral that can be used at either the project or enterprise level.
The model should reflect and work with the organisation’s purpose, goals, and values to help achieve the organisation’s vision.
A typical initial engagement period is 18 months.
IDEA offers various services, tool sets, and collateral that together provide a holistic approach to transforming into a high-performing way of working.
IDEA is not a big-bang approach but a holistic/company-wide approach. After seeing many transformations, it is clear that creating an exemplar team within a traditional environment may work for a little while until the team needs to work with other teams within the ecosystem. When a team is "book-ended" by traditional working teams, it is hard to be agile, and eventually, the external forces on the team reduce the effectiveness of the transformation.
Therefore, IDEA assumes that the whole company must take the first step on the agile journey together. This means company-wide training.
