Rolling Wave Planning

Title: "Rolling Wave Planning" by Paul K Taylor


An approach to schedule development which can be applied when in the early stages of a project  or study to control optimism bias on overall durations.


Bringing in Techniques such as rolling wave planning in conjunction with the USE OF estimating funnel techniques and future cost control will allow the company to improve its accuracy range on delivery timescales to be more in line with other industries.

The Rolling Wave process is a move away from relying heavily on highly detailed schedules in future phases, to only developing the detailed schedule phases when true underpinning is available.

It is important that the schedule before baselining or modelling is reviewed and effectively challenged to ensure that it is achievable based on the information available. The planning and scheduling using a rolling wave basis, accommodates lack of knowledge in futures Phases by adopting norms and stops the company applying unrealistic durations which cannot be underpinned.

The rolling wave approach involves more checks against new regression norms for work phases that are being developed and more rigorous reviewing of resource profiles, including labour from the supply chain.
