Hi,As such, we didnt come across any industry standard for milestone duration. Based on our experience, each project scope and nature will decide the milestone and helps to achieve it. In reality following are few top decision factors for setting and achieving the milestones.1) Durations are set based on the skill level of the GBs and the team.2) Actual availability of GB and Teams after kick of the Sixsigma project.3) Each Milestone needs to be revised based on the actual effort spend on Sixsigma project Vs estimated.4) If the sponsor /champion commitments are there, the project can achieve the targeted milestone.5) If the main project stream doesnt trouble the Sixsigma team, project milestones can completed as planned.6) If GB interest on Sixsigma project is reduced due to other constraint, entire milestone will be collapsed.7) If the identified Quick-wins fails after the define phase, team will lose the confident on the project which intern affect the milestone.8) If the data (Xs) are available in granular level, its easy to speed up the project from analyze phase onwards.In nutshell, Skill level, GB interest, Champion commitments, actual availability of the team, Quick results, team confident level on the tools and techniques, availability of the data decides on duration of each milestone. The Sixsigma project will be successfully completed on time, if the GB is considering these parameters during the milestone estimation and revise the schedule periodically based on this.
