Estimations are the baseline of every project. If you will perform unreliable estimates subsequently it will lead you and your team to burn the midnight oil or work over the weekends to meet timelines. We have practiced beautifully to take both project timelines and work-life balance seriously. We have developed better tactics to manage capacity and effective estimates to make the weekend work the exception rather than the rule.
