Why is building vision most important in effective leadership?”
There cannot be effective collaboration or learning environment without vision. Defining vision sets the foundation for all subsequent activities. Vision entails the setting of a direction, may it be on a high level such as for a corporation or on a lower level such as a project.
There can be collaboration without a clear division, but for what purpose? It cannot be effective for it does not follow objectives. Effective means that work achieves the desired outcome. Without a clearly defined vision, there is no clearly defined outcome. Hence, it would be wrong to speak of effective collaboration without vision.
For a project environment this implies that the first and foremost activity of any project has to be clarifying the vision and objectives of the project. Project objectives have to be “smart” (specific, measurable, achievable, relevant, time-boxed) and well understood and mutually supported by all key stakeholders. Do not start a project without a clear objective or it is likely to fail. In case a new project manager is assigned to an ongoing project she must first revisit the project objectives and check if they have been followed. If this were not the case, project objectives have to be re-evaluated and re-aligned among all key stakeholders.
