With Clockwyz, you can estimate the amount of time you think it will take to complete a task. When you or a team member log in hours on a task you would be able to compare how long it took to complete the task to how long you thought it would take. You can also plan how long it will take to complete the project, as a whole, by estimating how long each individual task will take.
This makes it easier to project when you would reasonably be able to complete your goal. You can input the estimated time a task will take by clicking on a task and entering your estimation under "Estimated Time".
