Flexible Project Management for Lean Product Development
Technology, businesses and market changes are so fast nowadays that product development needs to be extremely adaptable or it risks a failure. To accommodate to this situation, CMI Defence, a Belgium weapon systems specialist, implemented a flexible project management approach which is based on the agile methodology. While the traditional project management uses the waterfall model where each phase of a product’s life cycle takes place in sequence, agile project management is more flexible. This means that adapting to new customers’ requirements and needs is less likely to cause any real turbulence.
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 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.
Constant demand for shorter development and lead times, including several day-to-day business issues, for instance inefficient communication, coupled with the company’s continuous growth were clear indicators that a change was needed. CMI Defence found an answer to increase its product development efficiency by applying Lean Thinking practices.
Flexible project management is a method of incremental management for the product development activities in a highly flexible and interactive manner. It encompasses methods and tools of agile project management combined with the traditional project management best practices. CMI Defence uses a three-tier planning approach for maximal flexibility.

Implementation of a three-tier planning approach for flexibility
Project tiers are defined at the beginning of the project, but only the starting activities are defined in detail up-front. As the project progresses, details for the future activities are formulated based on the findings and master schedule needs.
For example, Work package 1 in Tier 1 is defined in detail at the beginning of the project, while Work packages 2, 3 etc. are only loosely defined (milestones, expected resources, etc.). As the work conducted in Work package 1 reaches completion, Work package 2 is defined in greater detail. This ensures that the project can adapt quickly to any change in customer requirements and other fluctuations.
Tier 1: HIGH-LEVEL MASTER SCHEDULE FOR ENTIRE PROJECT
- Project cost: FIXED
- Project duration: FIXED
- Project scope: FLEXIBLE
Tier 2: DETAILED PLAN
- Cost and workload of activities: FLEXIBLE
- Schedule and duration of activities: FLEXIBLE
- Planning: FLEXIBLE
Tier 3: WEEKLY TRACKING ACTION LIST
The various tasks related to the planned activities are detailed and distributed to the team members. The task planning and progress review are carried out on weekly stand-up meetings of the project team in the Obeya room using visual management tools.
How does your project management methods cope with agility and rapid (unexpected) changes? Can you quickly adapt to any customer requirement?

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.
