Planning

What is planning?Organizational process of creating a planThought processForecasting = predicting what future will like to beuncertainty

Planning

Defining project scopeDuration for tasksWork breakdown structure (tree structure; breaks down work in manageable components in terms of duration, size, …)Logical dependenciesCreate network

Last Planner System – Principles

Plan in greater detail as you get closer to doing work, becauseAll plans are forecasts and all forecasts are wrong!The longer the forecast, the more wrong it is!The more detailed the forecast, the more wrong it is!

Produce plans collaboratively with those who will do the workReveal and remove constraints on planned tasks as a teamMake reliable promisesLearn from breakdown

Last Planner System – PrinciplesConversation centered:

The right peopletalk about the right thingat the right level of detailat the right time

Planning in the sense of:Learning,Organizing andPromising
