If you end up constantly changing a small bit of a chart or analysis, it might be time to change the whole thing. This all sounds a bit cryptical, 2 examples:
- At the beginning of the project you were clueless about the competitors in the market and created a big 2x2 matrix that shows the market environment. As the team becomes more educated you notice that the only thing you do is moving dots of a specific subset of competitors in the bottom right corner, and adding footnotes, text bubbles, and explanations. It is time to rethink how you show the market and ditch that chart you created on day 2 of the project.
- In the first week of the project your created a rough DCF valuation model. Now, as the project progresses, the team is increasingly interested in scenarios. You end up going back to that first model, tweaking and goal seeking assumptions, and then recreate each scenario manually again. Maybe it is time to throw the model out, and build a spreadsheet that can handle multiple scenarios quickly.
There is no point in doing a slide update when a whole new visual or analytical approach is required.
