Workflows and Lifecycles work independent of each other, but they're also great when used together. One does not replace the other- each has its own value in project management.
The biggest difference is probably that you can only have one Lifecycle per project, but you could have many Workflows.
A Workflow is a step-by-step detailed list of tasks, whereas a Lifecycle mainly functions as a visual aid and shows the high level stages a client would go through. Think of a Workflow as a list of actions that need to be taken to complete a project or part of a project, and a Lifecycle as a tracking device for your progress on that project.
It is not unusual for a Workflow to have 15+ steps in it. Whereas, a Lifecycle generally only has 4 to 7 stages.
Here, you can see how the stages in a Lifecycle could correlate to steps in a Workflow.
The Lifecycle progress bar will reflect the progress of the project. As the Workflow step is completed, the Lifecycle stage will turn green.
You do not need to assign a Lifecycle to carry out your Workflow, just as you do not need to assign a Workflow to track progress on your Lifecycle. However, when they join together, results are maximized.
