What is a Fever Chart? How to use and how to read the Fever Chart. This chart is an essential tool of Critical Chain Project Management. The Fever Chart helps to track the project status based on two indicators: - The percentage of progress of the Critical Chain - The percentage of Buffer consumption
The ratio of these two indicators will enable to update the Fever Chart and will therefore be translated into a project status. The project is either "on-time", "at risk" or "late". This can be identified easily with the use of the three areas of the chart: - Green = on-time - Orange = at risk - Red = late
If a project is late, the project manager, the management and the team have to find solutions together to enable the project to finish on time.
Led by world expert Philip Marris, this course is designed to empower you with the knowledge and skills to excel in the realm of CCPM. During this training, you will delve into topics such as project scheduling, portfolio management, and the techniques specific to CCPM. 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.
La Gestión de Proyectos por la Cadena Crítica es uno de los componentes de la Teoría de las Restricciones, aplicada a la gestión de proyectos.
El objetivo es eliminar los márgenes individuales de cada tarea y mutualizar esta protección necesaria al final del proyecto, en un amortiguador (o buffer). ...
This is a short extract of Philip Marris' presentation during the TOCICO Critical Chain 2026 annual conference: "Service industries boosted by Critical Chain Project Management".
The extract discusses the phenomena of managing project portfolios by hydraulic pressure.
.... Sanjeev Gupta, explains how this new approach delivers radical results. This video explores a different approach to project execution based on Theory of Constraints (TOC) and Critical Chain Project Management (CCPM). Instead of adding more complexity, detailed plans, and heavy coordination, this approach focuses on simplifying execution, managing flow, and handling resource constraints effectively. [...] The idea is simple. Projects don’t improve with more control. They improve when execution is structured differently
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.
Sanjeev Gupta, founder and CEO of Realization Technologies, presents Critical Chain Project Management, Results and Lessons Learned during the 38th TOCPA Conference in Paris, France.
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.
Critical Chain Project Management (CCPM) is a project management approach developed in the late 90s that aims to finish your projects faster. This video explains the basic principles of Critical Chain project management through an Engineering to Order (ETO) project. However, Critical Chain Project Management can be applied to any projects: new product development, MRO, software development, ... How to build a Critical Chain ...

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.
A testimonial by Managing Director Frédéric Grehal, together with Raphael Ensinger and Michael Benmoussa, of Circor Aerospace & Defense. They faced significant challenges in their New Product Development projects. On-time delivery performance was below expectations, [...] capacity constraints in the Qualification Laboratory.
To address these issues, Circor Aerospace & Defense decided to implement Critical Chain Project Management (CCPM), starting with three pilot projects. During this phase, they increased the ...
Sanjeev Gupta, founder and CEO of Realization Technologies (the creators of the best-selling Critical Chain software Concerto) and Philip Marris, CEO of Marris Consulting (who has over 30 years of Theory Of Constraints experience) discuss Critical Chain Project Management (CCPM).
Video summary: Sanjeev's brief summary of what (Critical Chain Project Management (CCPM) is. His answer: "focus and finish".
Since CCPM is part of the Theory of Constraints (ToC) where are the constraints in project management? Answer: A) The Critical Chain of the project B) One category of the resources used C) The combination of A) and B) D) The market demand
Amdocs Customer Experience Systems Customized SW Development for Telecommunications. By Shalom Passy, Executive VP Before: -Market pressure to reduce cost and cycle time. -8 projects in crisis requiring CEO level attention in 2007. After: -14% increase in revenue/man-month. -20% reduction in cycle time. -8 projects were in crisis in 2007 then improved to 0 projects in crisis in 2008.
When managing projects the Critical Chain way you you manage uncertainty explicitly and transparently. You do not try to impose certainty on uncertainty as many top managers try and do. For each task you admit that the duration is unknown and you ask for 2 durations: an optimistic duration and a pessimistic duration. You must not ask people to commit to one duration because if you do that they will add padding or a buffer to be able to honour their commitment in an uncertain environment.

Lightning fast factory layout change using Critical Chain Project Management. 6.5 days instead of 8 weeks. A client testimonial by Safran. [...] they then decided to change the layout of the machines to improve the flow even more, simplifying the production flow and re-organizing the production lines by product families. The target of the new layout was to help reduce lead times even further, simplifying the flow of parts, and increasing productivity… Guillaume Brethenoux, Maintenance Manager in charge of this project used the Critical Chain Project Management Principles to challenge the initial planning of 8 weeks and eventually achieve the layout change of the shop floor in… 6.5 days!
