According to a PMI'S Research, More Than 50% of Projects fail (2019 - PMI Pulse of the Profession)

Deliver More Projects on Time


The Theory of Constraints is recognised for its effectiveness in maximising profits by acting on business processes. 

While understanding processes is somewhat facilitated by their repetitiveness, projects raise even more complex challenges

Critical issues include scarce knowledge, high variability, uncertainty, synchronisation , difficulty in recovery, with the pressure of requirements, budgets and delivery dates. For these reasons, more than 50% of projects fail to meet their objectives (source: PMI).

Find out how to improve all these aspects with the tools of the Theory of Constraints.

Solving The Core Problem in Project Environments


According to a recent study of the PMI, more than 50% of projects fails meeting their objectives (PMI - Pulse of the Profession)

Lack of clear scope, poor planning of activities, invisible or unmanaged constraints, contention of resources are some of the most common causes of project's failure.

When under budget pressure, a common practice is to postpone some specifications, thus very often projects barely meet the original requirements.

The situation worsen when resource contention spread across a Project Portfolio, where a single project may impact the entire portfolio with a domino effect.

Is there a better way to plan and control our projects?

Managing Scope, Budget and Timeline

Delivering more projects on time with Critical Chain and TameFlow

Driven by the core tenets of TOC, Critical Chain and TameFlow are superior PM methodology for complex Project and Knowledge Intensive Environments:

  1. They identify and exploit the constraints of a project or project portfolio

  2. They provide better algorithm to schedule work across resources

  3. They protect better the project from variability

Implementations of Theory of Constraints principles have shown productivity increase up to 270% through a better management of work. 

WeeonD is TameFlow and a-dato reference Partner for Italy and DACH.

TOC Tools to Improve Flow of Projects

Selecting the right projects is the first step for success: Project Gating and Throughput Economics  are key tools to be used for the ranking of project priorities

Selecting The Right Projects


Critical Chain is the operating approach of TOC to plan and execute projects.  It focuses management attention on the constraints  and  buffers

TOC Strategy & Tactics Tree are the key tools to define the necessary conditions - the requirements of the project - to be included in the Statement of Work to achieve the desired goal

Setting Goals & Requirements 


Lynx powered by a-dato is ranked as the best software to support project and portfolio management  with TOC Critical Chain and TameFlow approaches. We are the reference Partner for Italy and DAC

The Theory of Constraints provides the right tools to improve the delivery rates of strategic projects in every phase.

Success starts from the selection of the right projects to be executed: choosing the priorities of the portfolio, selecting the projects with  the highest probabilities to succeed; focusing resource; doing a rigorous staging and full kitting.

How to achieve the goals? The TOC Strategy and Tactic tree support management linking the necessary conditions (project requirements) to the goal.

Then projects activities needs to be scheduled and executed considering the constraints, exploiting them at best. 

The Right Tools To Improve Project Delivery Dates

With the right software solution

To implement the TOC principles we have chosen to partner with a-dato, the most known and implemented software tn that support Theory of Constraints logics.


On top of supporting the traditional Critical Chain approach, a-dato is also the first industrialized software that has implemented the TameFlow Approach, the methdology that encompassess TOC and consraints management  principles with the Agile and Kanban approach.

WeeonD is the reference partner of a-dato in Italy, Switzerland, Germany and Austria.
