Jan Willem Tromp is the opponent of Gantt planning. He explains his position in various blog posts and articles, claiming that Gantt charts are one hundred years old and suitable anymore for nowadays problems.

The use of Gantt-charts is no longer the best choice for modern project managers. This is because it does not account for all of the unknown variables involved when a project plan is created. (https://www.linkedin.com/pulse/current-way...an-willem-tromp )

Tromp co-owns Epicflow, previously known as Flow MPM, a project planning tool for managing multiple projects at the same time. The software is partly based on critical chain project management with extended resource capabilities. The novelty of Ponsteen and Tromp’s approach consists in the Flow method; Epicflow helps project management experts release bottlenecks as soon as they appear and simplifies multi-project planning.
