Planning: Time
Planning time management involves identifying all the activities required to satisfy the contractual obligations of the project, i.e. to deliver all the WBS items (deliverables) to the customer. In general practice the processes above are blended into a single effort of schedule development, but in reality, whether done formally or informally, all the above processes are completed by the project team whether they are documented as separate efforts or not.
6.1 Plan Schedule Management
Process Definition
Planning schedule management results in creating a plan for developing, controlling and closing the project schedule. It is important to note that the plan is about how the schedule will be managed, not the actual schedule itself. It should clearly identify the tools that should be used, such as Microsoft Project, recommended templates, the configuration management and control processes that should be followed, reporting requirements and closure process.
Process Assessment
A schedule management plan has never been useful for me. My organizations usually have existing processes embedded into the culture and followed by teams. Schedules are done in MSProject, and progress reporting is done weekly with percent complete identification. I've never seen a need for this process.

6.2 Define Activities
Process Definition
With the scope baseline completed, the first step in schedule development is to define the activities required to produce the project deliverables, as outlined in the WBS. This list of activities should result in the completion of each work package in the WBS.Process Assessment
This first step, defining the activities required to create and deliver each WBS element is critical in the creation of a good schedule. Making sure that activities are identified for each and every WBS element is often overlooked, with focus skewed toward product development. Things like training, spares and support facilities are frequently neglected.

6.3 Sequence Activities
Process Definition
After the activities have been defined it is necessary to arrange them in the proper sequence for execution. This is done by creating logic relationships between the activities in the scheduling software program, and can also involve lead and lag times.
Process Assessment
This second step in building a schedule, sequencing the activities identified in process 6.2, helps build a better picture of how the project will be executed. This process often results in further decomposition of activities.

6.4 Estimate Activity Resources
Process Definition
After the activities have been identified and sequenced that achieve the desired project scope, the project manager must determine which resources are required for each activity. These resources can include people, equipment, material and supplies.
Process Assessment
Estimating activity resources is one of the most difficult exercises in project management. Activities frequently take more resources than estimated, especially when it comes to labor. Also, the resources required often change over time as activities and deliverables become more well understood. This is one of the most pain-in-the-butt processes in project management. Of course, it's also one of the most important.

- Retirement Party RBS: The RBS (Resource Breakdown Structure) is one of the outputs of the "Estimate Activity Resources" process. This homework assignment created an RBS for a retirement party.
6.5 Estimate Activity Durations
Process Definition
The availability of resources often affects how long it takes to accomplish tasks on a project. Therefore the activity durations are not estimated until after the available resources have been assigned.
Process Assessment
As with estimating activity resources, estimating activity durations is very difficult. Activities frequently take more time than estimated, especially when it comes to labor. Also, the duration required often changes over time as activities and deliverables become more well understood.

6.6 Develop Schedule
Process Definition
The schedule is the final result of the preceding processes, define activities, sequence activities, estimate resources and estimate durations.
Process Assessment
As with 4.2 Develop Project Management Plan, this isn't a process so much as a compilation of the results of the other time management processes. Once activities have been identified and sequenced, and estimates made for resources and duration, the schedule is effectively built.
