PROJECT TIME MANAGEMENT Is the process required to manage timely
completion of the project There are 7 processes
Plan Schedule Management Define Activities Sequence Activities Estimate Activity Resources Estimate Activity Durations Develop Schedule Control Schedule

6.1 PLAN SCHEDULE MANAGEMENT Is the process of establishing the policies, procedures,
and documentation for planning, developing, managing, executing and controlling the project schedule.
Provides guidance, direction on how the project schedule will be managed throughout the project.
Inputs Tool&Techniques Outputs
.Project management plan
.Project charter
.EEF
.OPA
.Expert Judment
.Analytical techniques
.Meetings
.Schedule management plan

6.2 DEFINE ACTIVITIES Is the process of identifying the specific actions to be
performed produce the project deliverables. The key benefit of this process is to break down work
packages into activities that provide a basis for estimating, scheduling, executing, monitoring and control the project work.
Inputs Tool&Techniques Outputs
.Schedule management plan.Scope baseline.EEF.OPA
.Decomposition
.Rolling wave planning
.Expert judment
.Activity list
.Activity attributes
.Milestone list

6.3 SEQUENCE ACTIVITIES Is the process of identifying and documenting
relationship among the project activities. The key benefit of this process is that it defines the
logical sequence of work to obtain the greatest effeciency given all project constraints.

ESTIMATE ACTIVITY DURATIONS (TOOLS & TECHNIQUES)
Analogous Estimating (Top down): estimates using historical data from a similar activity or project less costly, less time -> less accurate
Parametric Estimating: estimates using a statistical relationship between historical data and
other variables -> higher accuracy 3-points Estimating:
Also called Program Evaluation and Review technique (PERT) Use for time and cost estimation Expected calculated from Most-likely, Optimistic, Pessimistic Expected = (P + 4M + O)/6 Standard Deviation = (P - O)/6
Group decision-making techniques: brainstorming… Reserve analysis (buffer): includes contingency reserves

contraints to create a project schedule model.Inputs Tool&Techniques Outputs
.Resource optimization techniques.Modeling techniques.Leads and lags.Schedule compression.Scheduling tool
.Schedule baseline
.Project schedule
.Schedule data
.Project calendars

CRITICAL PATH METHOD Critical Path is the longest duration path Identify the shortest time needed to complete a project There can be more than one critical path Near-critical path is the path that has close in duration to
critical path Float (Slack)
Total float: the amount of time an activity can be delayed without delaying the project end date or intermediary milestone.
Free float: the amount of time an activity can be delayed without delaying the early start date of its successor(s).
Project float: the amount of time an activity can be delayed without delaying the externally imposed project completion date required by customer/management.

CRITICAL CHAIN METHOD Is a schedule method that allows the project
team to place buffers on any project schedule path
Type of buffers Project buffer Feeding buffer Resource buffer
