Of the following steps in developing a cohesive early-project Strategy Design, which one allows the team to present simple concepts and brainstorm potential solutions?

The correct choice is the step of Idea Generation. This phase is essential for encouraging creativity and fostering an open environment where team members can present simple concepts without the constraints of extensive research or specific parameters. During Idea Generation, team participants come together to brainstorm potential solutions and explore a wide range of possibilities without the fear of critique or the limitations of practicality at this stage. This creativity lays the groundwork for further refinement and development of ideas in later stages of the strategy design process.

In contrast, Challenge Framing focuses more on defining the problem and setting the context for the project rather than generating ideas. Project Research involves gathering data and insights about the problem and the context, which is more analytical and less about brainstorming. Craft of Key Insights is about synthesizing and refining ideas and findings into actionable insights, which comes after the initial generation of ideas. Each of these steps plays a significant role in the overall project strategy, but Idea Generation distinctly highlights the collaborative brainstorming aspect essential for cultivating innovative solutions.
