Let's discuss Capabilities Analysis. A capabilities analysis is one of the critical tools in any strategic analysis. It is our primary tool for analyzing the internal capabilities of an organization. There are three primary steps for thinking about a capabilities analysis. But first, is to identify those capabilities. The first way to do that is by identifying the value chain, understanding how does a company take various raw material and turn that into products and services? What are the steps along the way and then what are the secondary activities, be it human resource practices, research and development and the like, that then supports the creation of those goods and services. These become the capabilities. Once we outlined these capabilities, we want to unpacked them further and understand what are the underlying people processes and systems that generate these capabilities at the end of the day? So for example, Apple might have a capability of being creative, and the question is, what are the people, processes, and systems that they have in place to allow for this creative capability that they possess? Once we've identified the capabilities and the underlying people, processes, and systems that generate them, then we need to ask ourselves about alignment. To what degree does the set of capabilities work together as a cohesive system internally, as well as create value that creates value for those externally to the organization. So, alignment both internally and externally. Last but not least, we want to ask ourselves a set of sustainability questions here. And by this we mean, do these set of capabilities first create competitive advantage, and second, whether that competitive advantage can be sustained over time. So the the first question you want to ask is about imitability. Are these capabilities imitable by other organizations or other companies? The second thing you want to ask are, are these capabilities durable? Will they persist into the future? Will they last or will they degrade over time? We can think of both human and physical assets as both of things that will eventually degrade over time. There might be other challenges to durability, such as whether there's a change and the need for that capability moving forward. So to summarize, capability analysis is a critical tool in your toolkit. It helps us understand the internal environment of the organization. It helps us identify the capabilities the firm has and ultimately assess whether these capabilities provide competitive advantage or not and whether they're sustainable moving forward.
