Summary
This document provides an overview of project schedule management, including knowledge areas, time management concepts, and critical path method (CPM). It details different processes involved in project schedule management, such as defining activities, sequencing activities, estimating activity durations, developing schedules, and controlling schedules. It also explains how to analyze project duration and identify the critical path.

Milestones are easy to achieve and are always achieved through one main activity? FALSE 2. After defining project activities, the next step in project time management is developing the schedule? FALSE 3. A Tracking Gantt chart is based on the percentage of work completed for project tasks or the actual start and finish dates? TRUE 4 PLANNING.

Plan schedule management – establishing the policies, procedures, and documentation for planning, developing, managing, executing and controlling project schedule 2. Define activities – identifying and documenting specific actions to be performed to produce project deliverables. 3. Sequence activities – identifying and documenting relationships among the project activities. 4. Estimate activity durations – estimating the number of work period needed to complete individual activities with the estimated resources. 5. Develop schedule – analyzing activity sequences, durations resource requirements and schedule constraints to create the project schedule model. 6. Control schedule – monitoring the status of the project to update the project schedule and manage changes. K AU N O TE CH N OLO GI JOS UN I V ER S I TE TAS Project duration analysis Once the dependence of the activities and the duration of them have been established, the following questions can be answered: What is the total duration of the project? Which activities/work packages determine the duration of the whole project? Which activities/work packages need to be reduced to reduce the duration of the whole project? Which activities/work packages have time to spare? When do we need to start and finish specific activity/work package to complete the project on time? K AU N O TE CH N OLO GI JOS UN I V ER S I TE TAS Critical path method (CPM) (1) A critical path method (CPM) is used to estimate the minimum project duration and determine the amount of schedule flexibility on the logical network paths within the schedule model. A critical path is the sequence of project activities that represents the longest path through a project, which determines the shortest possible project duration. Float/slack, is the amount of time an activity, network path, or project can be delayed from the early start without changing the completion date of the project. K AU N O TE CH N OLO GI JOS UN I V ER S I TE TAS Critical path method (CPM) (2) Earliest start time (ES): This is the earliest time that a task can be started in your project. You cannot determine this without first knowing if there are any preceding tasks. Latest start time (LS): This is the very last minute in which you can start a task before it threatens to upset your project schedule. Earliest finish time (EF): The earliest an activity can be completed, based on its duration and its earliest start time. Latest finish time (LF): The latest an activity can be completed, based on its duration and its latest start time K AU N O TE CH N OLO GI JOS UN I V ER S I TE TAS Step 6. Critical path diagram ▪ The critical path is the longest path of the network diagram. ▪ The activities in the critical path have an effect on the deadline of the project. ▪ If an activity of this path is delayed, the project will be delayed. © KTU 2023 10 Critical Path Method Example ▪ Consider that your project has 8 activities with durations and dependencies as indicated in the table. You have to draw a network chart and determine the critical path.

Project schedule management Project schedule monitoring (Gantt’ diagram) A Gantt chart is a type of bar chart, developed by Henry Gantt, that illustrates a project schedule. K AU N O TE CH N OLO GI JOS UN I V ER S I TE TAS A project milestone is a management tool that is used to delineate a point in a project schedule. Gantt chart A bar chart format; Allows to check progress with a quick glance: Visual display of the whole project; Timelines and deadlines of all tasks; Relationships and dependencies between the various activities; Milestones; Project phases. 18 PLANNING. Project schedule management Project milestones: to identify key events during the project period; to track and evaluate project progress. to identify the beginning or end of work packages or phases. ✓start of project, end of project ✓ start / end of installation ✓ approval, commencement of enforcement ✓ submission, takeover, opening ceremony ✓ acceptance act ✓ decisions to take / not follow up ✓ payments and other contractual dates…...........
