The standard for project management

Lessons learned register. 

Described in Section 4.4.3.1. Lessons learned earlier in the project with regard to 

developing cost estimates can be applied to later phases in the project to improve the accuracy and precision of 

the cost estimates.

Project schedule. 

Described in Section 6.5.3.2. The schedule includes the type, quantity, and amount of time 

that team and physical resources will be active on the project. The duration estimates (Section 6.4.3.1) will 

affect cost estimates when resources are charged per unit of time and when there are seasonal fluctuations 

in costs. The schedule also provides useful information for projects that incorporate the cost of financing 

(including interest charges).
