Project Schedule Management – Overview

  1. Seven project management processes in total
    1. Six processes are in the planning phase
    2. One process in the control phase
    3. This domain has no processes in executing!

6.1 – Plan Schedule Management

  1. Just as any other domain, the first action is to plan how to manage schedule in our project.
    For example – what units are used for time management (weeks/days/months, etc), what tools and methods are used for reporting, the frequency of reporting and so.
  2. Inputs – Project management plan, project charter, enterprise environmental factors, organizational process assets.
  3. Tools – Expert judgement, Analytical techniques, Meetings.
  4. Outputs – Schedule management plan.

6.2 – Define Activities

  1. In this process we take the work packages from the WBS and decompose them to individual tasks. In practice, we can then enter these tasks into our project management software.
  2. Inputs – Schedule management plan, Scope baseline, enterprise environmental factors, organizational process assets.
  3. Tools – Decomposition, Rolling wave planning, Expert judgement.
  4. Outputs – Activity list, activity attributes, milestone list.

Activity list is a document, usually formatted as a table, which itemizes all scheduled activities for the project along with detailed description of the work to be performed for each activity. This list may be very long, or very short, depending on the complexity of the project. When creating the list, the project team should ensure to provide as much detail as possible in describing the scope of work for each activity so that all members involved can gain a thorough and clean understanding of the activity.

For example

Activity List




Project: Redecorate Office



Date: 1/11/16

Activity ID No

Activity Name

Description of Work



Choose new furniture

This activity consists of reviewing all suggested designs and models. Choosing the best options base on price, availability, and design.

J. Doe


Submit purchase of new furniture

This activity consists of getting the cfo and ceo signature on the PO document and send it to the vendor.

D. Write is responsible for this activity


Receive furniture when shipment arrives

This activity consists of arranging a clear spot for the truck to unload the furniture, arranging forklifts to move them from loading bay to the elevator and office floor. Unloading cannot start before 11AM due to pick usage of the freight elevator.

K. White is responsible for this activity


Disconnect all computers from tables

This activity includes making sure that all the computers are disconnected to allow disassembling of the desks.

L. Black has primary responsibility and J. doe is the alternate


Disassemble the old furniture

This activity includes disassembling the old (current) furniture from all offices and meeting rooms

K. White is responsible for this activity


Assemble the new furniture

This activity includes assembling the new furniture in all offices and meeting rooms

K. White is responsible for this activity


Re-connect all computers

This activity includes computers and other electrical items for employees on new furniture. Must wait 24 hours before placing new Hardware on the tables.

L. Black has primary responsibility and J. doe is the alternate





  • Activity attributes – Those are the multiple attributes associated with each schedule activity in the activity list.  Activity attributes include activity codes, predecessor activities, successor activities, logical relationships, leads and lags, resource requirements, imposed dates, constraints, and assumptions (PMI Glossary).
  • Milestone list – A list identifying all project milestones and normally indicates whether the milestone is mandatory or optional (PMI Glossary).

6.3 – Sequence Activities

  1. This process is about identifying the relationships between activities.
    Each activity (except for the first and the last ones) has at least one task as a predecessor, and at least one task as a successor.
  2. Inputs
    1. Schedule management plan – This is an input because it defines the guidelines on how to schedule, measure and report activities in the project
    2. Activity list, Activity attributes, millstone list – These inputs are here because they are the outputs of the previous process, and because they are the detailed description of the work that needs to be done.
    3. Project scope statement – when need to make sure that we always adhere to the project scope.
    4. enterprise environmental factors, organizational process assets.
  3. Tools – Precedence diagramming method (PDM), Dependency determination, Leads and lags
  4. Outputs -Project schedule network diagrams, Project documents updates.

Activity dependency types

  1. Finish to Start (FS) – Most commonly used, linear connection between one task completion to its successor start.
  2. Finish to Finish (FF) – The tasks should end at the same time.
  3. Start to Start (SS) – The tasks must start at the same time.
  4. Start to finish (SF) – Task #1 can start only when task #2 ended. For example, the day shift can start only after night shift has ended.

Leads and Lags

Every activity that represents “waiting” it is better to show as lag, instead of “waiting” activity, for example: paint the wall for the first time –> wait for paint to dry (lag) –> paint second time.


Techniques to determine dependencies

  1. When task #2 can’t be done in a different way (you can’t paint second time before painting for the first time)
  2. HR, financial or other constraints (use only 1 person to paint, instead of two)
