The concept of maturity model was firstly introduced by Watts Humphrey of Carnegie Mellon University in 1987 with the goal to improve the performance of software development process. Since then, the maturity model has been adopted by many disciplines. This article will present to you 5 types of maturity model as follows,
1. Process Maturity ModelThere are so many supply chain maturity model produced by consulting or independent research firms. Anyway, the most widely cited maturity model is the work named "The development of a supply chain management process maturity model using the concepts of business process orientation" from McCormack and Lockamy III in 2004.
In order to use the maturity model, you have to check which statement illustrates your current situation. After that, set your own target to higher level. Then you can determine the "gap" between your existing level and desired level and then change business practices to close the gap.
As you may notice, supply chain maturity model is like "KPI" but it's expressed qualitatively and you have to use it strategically.
2. Procurement Maturity ModelThere are lots and lots of procurement professionals who can't really break away from "buy cheapest things" mindset. There are so many things that we can do to strategically help company to create value. Handfield and Straight provided a very useful maturity model for procurement function as below,
This maturity model is so useful in the way that each description is actually one best practice that you can implement.
3. NPD Maturity ModelModern supply chain strategy goes far beyond "cost reduction" or "service improvement". Many supply chain professionals take part in a revenue generation project such as New Product Development "NPD".
Even though the NPD initiative is often viewed as a marketing thing, in the reality, every company relies on the innovation from its suppliers and supply chain professionals are important part of it. So we can actually lead a NPD process and this maturity model will be useful to create a good NPD strategy. Please note that the market studies can also mean "supply market" so supply side information is also useful.
4. Lean Maturity ModelEvery supply chain needs a certain degree of lean capabilities. But, if you're not in the automotive industry where lean practices are widely adopted, how you can develop a lean roadmap within your organization?
Lean Maturity Model is the work from Lean Aerospace Initiative at MIT. It provides you with a broad overview of lean implementation. What you need to do is to determine which lean practices can be applied in your industry and how you can achieve a higher level of adoption.
5. S&OP Maturity ModelThe last maturity model today is the work from Larry Lapide of MIT. S&OP has been widely implemented since its inception in 1980s but many companies still choose to incorporate some of S&OP practices into a generic production meeting.
There is no silver bullet solution for supply chain problems. Each technique produces different result. This article has demonstrated the usefulness of simple technique like the supply chain maturity model and I hope you can incorporate this tool to diagnose your supply chain operations.
