David Griffiths, a Project and Program Management Trainer, underscores the value of a program environment in managing projects. Such an environment offers enhanced coordination of all related projects. Moreover, it makes it more straightforward to advocate for necessary projects to senior management. Specifically, Griffiths mentions the importance of "enabling projects", which are crucial to achieve the desired outcomes from other projects. By using a program environment, stakeholders can see the bigger picture and understand the interconnectedness of various projects, thereby making the entire process more logical and coherent. He concludes by expressing gratitude to his audience.
