Keep Tasks Green

A green schedule: Make sure that all tasks in your schedule are green

Philosophy of green schedules

As part of my weekly status calls with project stakeholders, I review two types of tasks:

• Open tasks: light-bulbs indicate whether someone should be working on the task (see light-bulb blog-post)
• Late tasks: red & yellow tasks are tasks that have missed or will miss their finish dates (see traffic light blog post)

Every status call invariably has a few tasks with yellow or red traffic lights. Some tasks show up late even though they completed on time.

Remove red & yellow lights: Change the finish dates to get green tasks and thus see if major milestones will still finish on time

This normally happens if I, as the PM, was not on the email chain mentioning the task had been completed. In which case, I close the task once notified. And the late indicator disappears.

But there are frequently tasks where the task owner says that the task requires more time or he hasn't started working on it. In which case, I ask for the new ETA and update the finish date. At which point the late indicator should  turn green.

Benefit of green schedules

Setting new finish dates, as opposed to leaving finish dates unchanged, helps show how finish dates for downstream tasks are changed. And as a result, whether major milestones are impacted. If red diamonds (late indicators for milestones) appear as a result of a task owner's new finish date, the whole team on the call sees the impact. And then it's trivial to negotiate for an earlier ETA.

Of course, you see this benefit only if you've correctly defined your predecessors & successors. But that's a topic for another blog post.
