1. Project Time Management Third Knowledge Area of PMBOK

2. Project Time Management Processes Define Activities Sequence Activities Estimated Activities Resources Estimated Activity Durations Develop Schedule Control Schedule

3. Step-1:Define Activities Input: Scope baseline Tools & Techniques: Decomposition (PWP to activities to produce WP Deliverables) Rolling wave planning Templates (A standard activity list from previous project) Expert Judgment (Project Team Members & or other experts) Outputs: Activity List (All scheduled activities required on the project) Activities Attributes * next screen showing attributes Milestone List (Significant point or event in a project)

4. Sequence Activities Sequence activities is the process of identifying and documenting relationship among project activities. Input: Activity List Activities Attributes (Next Screen) Milestone List (a significant point or event in the project) Project Scope Statement Tools & Techniques: PDM (Precedence Diagramming Method) Dependency Determination Applying Leads & Lags Schedule Network Templates Outputs Project Schedule Network Diagrams Project Document Updates

6. Activity Attributes Activity ID WBS ID Activity Name Activity Description Predecessor Activities Successor Activities Logical Relationship Leads and Lags Resource requirements Imposed Dates, Constraints Assumptions Person responsible for work execution Geographic Area

7. Sequencing Activities How to do it!!! Precedence Diagramming Method: Finish to Start (FS) Finish to finish (FF) Start to Start (SS) Start-to-finish (SF) Finish to start is the most commonly used type of precedence relationship. The start-to-finish relationship is most rarely used but is included to complete list of the PDM relationship types. FS: The initiation of the successor activity depends upon the completion of the predecessor activity FF The completion of the successor activity depends upon the completion of the predecessor activity SS: The initiation of the successor activity depends upon the initiation of the predecessor activity SF The completion of the successor activity depends upon the initiation of the predecessor activity

8. Sequence Activities Dependency Determination Mandatory Dependencies: Also referred as hard logic Discretionary Dependencies: Also called as preferred logic, preferential logic or soft logic External Dependencies: It involves a relationship between project activities and non-project activities. These dependencies are usually outside the project team controls. Applying Leads and Lags A lead allows an acceleration of the successor activity A lag directs a delay in the successor activities. Example: A technical editing team can begin editing the draft of a large document 15 days after they began writing it. SS with 15 day lag.

9. Sequence Activities Schedule Network Templates Standardized schedule network diagram templates can be used to expedite the preparation of network of project activities. They can include an entire project or only a portion of it. Portions of a project schedule network diagram are often referred to as a subnetwork or fragment network. Subnetwork templates are especially useful when a project includes several identical or nearly identical deliverables, such as floors on a high rise office building.

10. Sequence Activities Outputs: Project Schedule Network Diagrams: Project Schedule Network Diagrams. It can be drawn manually or through project management software. It can include full project details or have one or more summary activities. Project Document Updates Project documents that may be updated include: Activity list Activity attributes

11. Estimate Activity Resources Estimate activity Resources is the process of estimating the type and the quantities of material, people, equipment or supplies required to perform each activity. The estimate activity resource process is closely coordinated with the estimate cost process.

12. Estimate Activity Resources Inputs: Activity List Activity Attributes Resource Calendar specify when and how long identified project resources (people, equipment & Material) will be available during the project. Tools & Techniques External Judgment Alternative Analysis (Make or buy, Machinery & Tools) Published estimating data (production rates & unit costs of resources) Bottom-up estimating (when activity cannot be estimated with confidence) Project Management Software (Plan, organize, manage resource pools and develop resource estimates. Outputs Activity resource requirements Resource breakdown structure Project document updates (activity List, Activity attributes & Resource calendar.

13. Estimate Activity Duration Estimate activity duration is the process of approximating the number of work periods needed to complete individual activities with estimated resources. Input: Activity List Activity Attributes Activity Resource Requirement Resource Calendars Project Scope Statement Tools & Techniques Expert Judgment Analogous estimating (Duration, budget, size, weight & complexity from a previous project) Parametric estimating (square footage – cost budget & duration) Three-point estimates (PERT) Reserve analysis (Cater for schedule uncertainty) Outputs Activity duration estimates (@ weeks +- 2 days etc) Project document updates (activity attributes, assumptions made in developing the activity duration)

14. Develop Schedule Develop Schedule is the process of analyzing activity sequence, duration, resource requirements and constraints to create project schedules Input Activity List Activity Attributes Project Schedule Network Diagrams Activity Resource Requirements Resource Calendars Activity duration estimates Project Scope Statement Tools & Techniques Schedule network analysis Critical path method Critical chain method Resource Leveling What-if scenario analysis Applying leads and lags Schedule compression Scheduling tool Output Project Schedules (milestone chart, bar charts, project schedule network diagrams) Schedule baseline Component of project management plan with baseline start & finish dates. Schedule Data (resource requirement by time period in resource histogram best & worst case Project document updates (Activity resource requirements, activity attributes, calendar, risk register)

15. Control Schedule It is the process of monitoring the status of the project progress and manage changes to the schedule baseline. It is concerned with Determine the current status of the project schedule Influencing the factors that create schedule changes Determining that the project schedule has changed Managing the actual changes as they occur Input: Project Management Plan Project Schedule Work performance information

16. Control Schedule Tools & Techniques: Performance review Measures, compares, and analyzes schedule performance such as actual start and finish dates, percent complete and remaining duration of work in progress. Also reviews if corrective action is required Variance Analysis: Schedule performance measurements are used to assess the magnitude of variation to the original schedule baseline. Project management Software It provides the ability to track planned dates versus actual dates and to forecast the effects of changes to the project schedule.

17. Control Schedule Tools & Techniques: Resource Leveling To optimize the distribution of work among resources What-if Scenario Analysis Used to review various scenarios to bring the schedule into alignment with the plan Adjust Leads and Lags To find ways to bring project activities that are behind into alignment with plan Schedule Compression : (Fast Tracking & Crashing) Scheduling Tool Data is updated and compiled into the schedule to reflect actual progress of the project and remaining work to be completed.

18. Control Schedule Outputs Work performance measurements Organizational Process Assets Updates Change Request Project management plan updates Schedule Baseline Schedule management plan Cost baseline Project Document Updates Schedule data Project Schedule
