CMI Defence’s Lean Product Development Journey
Continuous growth and market demanding shorter development times, lead CMI Defence, a weapon systems manufacturer from Belgium, to transform its product development approach. In 2013, the company embarked on its Lean Product Development journey by setting up for lean. This initial step aimed at producing a strategic roadmap for the implementation of different lean product development enablers to systematically develop, implement and roll-out several smaller improvement initiatives including the application of set-based concurrent engineering (SBCE), A3 thinking for problem-solving, agile project management and putting in place effective training and coaching methods.
CMI Defence is one of the world’s leading companies in multifunctional, high-effect weapon systems for light and medium weight armored vehicles. CMI Defence is a part of the CMI Group, which in 2014 generated nearly 900 million euro, 38% of which came from CMI Defence with the remaining 62% spread evenly among the Group’s three other sectors.
A constant demand for shorter development and lead times, including several day-to-day business issues, coupled with company’s continuous growth was a clear indicator that a change was needed. CMI Defence found an answer for increasing its product development efficiency applying Lean Product Thinking practices.
Being a growing organization means there is a need for continuous improvement if this growth is to be sustained. CMI Defence embarked its lean product development journey in January 2013. Before the kick-off of the lean initiative, CMI Defence identified several challenges, which later helped the organization form a strategic plan for the introduction and application of various lean methods, tools and techniques.
The starting point of the CMI Defence’s journey was an activity called “lean set-up”, which aimed at producing a strategic roadmap for the implementation of different lean product development enablers. This resulted in systematic development, implementation and roll-out of several smaller improvement initiatives such as set-based concurrent engineering (SBCE), A3 thinking for problem-solving, agile project management, the development of a “lean mindset” across the engineering department and more.
CMI Defence’s Lean Product Development Journey
Throughout its lean journey, CMI Defence established best practices in several aspects of Lean Product Development. These practices were identified and structured according to the four building blocks of the Lean Innovation Model. Below are just some of the best practices identified and described in the CMI Defence chapter of the Lean Product Development Best Practices Book.
1) STRATEGY AND PERFORMANCE
In the past, CMI Defence used an engineered-to-order (ETO) system to develop new products, due to the high complexity and individuality of their solutions. However, it takes a long time for a complex product to be engineered to order and, with customers demanding their products in shorter and shorter times, CMI Defence decided to make a shift from ETO to a system closer to configure-to-order (CTO). This shift allowed CMI Defence to develop and implement a platform design, enabling parts standardization and categorization.
2) SKILLED PEOPLE AND COLLABORATION
The combination of platform design and SBCE constitutes a very complex approach and, as such, it requires highly trained people skilled of using it, and maximizing its potential. For that reason, CMI Defence invests heavily in training and education of its management and engineering teams. The teams often attend one-day conferences, workshops and courses with world-renowned lean product development specialists. Product Development teams also experiential trainings, such as learning by using serious games, which are fun and engaging, and therefore, often yield more impressionable and lasting results.
3) EFFICIENT PRODUCT DEVELOPMENT PROCESS AND KNOWLEDGE BASED ENVIRONMENT
A shift from ETO to CTO system permitted the development and implementation of a platform design paired with a set-based concurrent engineering (SBCE). While SBCE can ensure a high level of innovativeness at a reduced risk, a platform design can provide common parts and modules in order to reduce the time to market. In 2015 CMI launched a pilot project for a medium-caliber feeding system to further explore SBCE and the opportunities it offers. As a result, CMI Defence developed a brand new, patent pending, design which would have very unlikely been developed using their traditional processes and tools.
4) CONTINUOUS IMPROVEMENT AND CHANGE
CMI’s key contribution to their continuous improvement journey focuses on a constant standardization of the design practices. This is achieved by using Standard Operating Procedures (SOP), which are generated, regularly reviewed and updated, and released in alignment with the top management.
Consolidated best practices as identified in CMI Defence, structured around the Lean Innovation Model

CMI Defence’s Best Practices are presented and described on more than 25 pages in the Lean Product Development Best Practices book. CMI Defence’s chapter is only one out of the 10 chapters presenting the real-world application of lean product development in multinational companies.
The hard copy of the book with the 10 cases is available for only 74.99 EUR.
