Additionally, you will have the opportunity to hear directly from Marris Consulting clients through numerous testimonies and case studies. These real-world examples will showcase how organizations have successfully implemented Critical Chain Project Management and its positive impact on their projects. Learning from their mistakes and their tips and tricks applied in their environment will enhance your learning experience and enable you to apply the Critical Chain principles to your own environment/challenges.
Aeronautical industry: How to master your ramp-up with the Theory Of Constraints. How to produce more despite a stressed-out Supply Chain. Watch the video recording of my recent webinar on the subject. A 22-minute executive summary. This is our point of view based on the 40% of our assignments that are in the aeronautical industry.
The Theory Of Constraints is all about finding what element prevents you reaching your goal. In this case the goal is to produce more. So, the approach is simple: find the “bottleneck” and focus on how it can produce more.
Often, but not always, another important thing that needs to be done in parallel is to reduce the level of inventory. We do this using the “2 for 1 rule”.
I talk not only about producing more but also how to accelerate project portfolios since ramp-ups often require Capex projects, production transfers from one plant to another, new product industrialization, etc.
Mukhtar Kadiri the host of the "PM Therapy Podcast" invited Philip Marris to discuss the challenges of project management. This is an extract where they discuss the main reasons why projects are late. - The management of uncertainty - The local safety in individual tasks - The development of micro-management - The lack of reliable data on portfolio capacity - The hydraulic pressure solution used by most organizations - The chaos generated by trying to keep everybody busy.
Philip Marris explains the problems of managing the capacity of an organization in project environments. How long does it take to write a piece of software code or find a new supplier? All the numbers are wrong. So management work on the principle of hydraulic pressure: the more projects I force into the system the more will come out. As a result the organization goes into multitasking madness and very little work gets finished.
“PM Therapy” podcast by Mukhtar Kadiri. Mukhtar was recently ranked N° 1 as the most influential actor in Project Manager in Canada. During the podcast on Thursday the 5th of March at 12:15 Toronto time (UTC-5) or 6:30pm Paris time (CET) we will discuss many aspects of project management. I will be emphasizing how it is quite easy to manage projects differently and significantly […] We plan to cover among other things:

Age combined with excessive flight hours had put much of a legendary Naval aircraft fleet on the ground. The US Navy needed a better way to keep their older and overworked F/A-18 jets properly maintained and on the job. Realization's Focus & Finish approach to managing workload and resources helped the Navy radically improve efficiency and keep the jets flying.

"The principal advantage of this approach is that the developers themselves have a close relation with the clients. This results in high motivation, flexibility and low overhead. It is a proven technique and has been in use on software projects for at least 10 years." i.e. since 1973! This is 20 years before Scrum, 13 years before the 'New New Product Development Game' HBR article and is 52 years ago.
