If there is ever an art to delivering technology, it’s about knowing when and how to prioritize events as they unfold. Some events are small and may only need an email. Others, a simple test or instant message may do. At higher levels of modality are direct phone calls with screen sharing, Skype, or even face to face meetings.
A recognition of when there is not enough or too much ceremony for the roles involved. If a dozen emails go by for something that would take two minutes to discuss, then using email is the wrong modality. Sometimes, that isn’t clear until the communication unfolds, but immediately change the mode if you see that it is dragging down in the form of communication provided.
Also, too much communication can happen. If a meeting takes up more time than actual doing the work or logging the work is taking up more time than just doing it, the process should be questioned.
It’s all about business alacrity and a good project manager, and any business professional, should always look for ways to reduce waste in delivery.
