The modern Agile movement is the coming together of three different timelines from the software industry's industrial heritage: Product Development, Engineering, and Lean Manufacturing.

We looked at the three most popular Agile methods, and how they represent each of these timelines.

We discussed how all three methods have a degree of crossover or similarity. For instance, Scrum encourages a high degree of transparency, and Scrum teams often communicate this using a visible workspace. This is very similar to the concept in Kanban of making work visible.

We also discussed how many companies are improving their results by mixing and matching from two or more approaches.

In the next chapter, we're going to give a practical overview of how to get our team started with Scrum.
