We leadWhat is project?
• A project is a collection of tasks that must be completed within certain time frame, with specific cost & quality.
We leadWhat is Project
What do we want?
Input• Land • Money (capital)• Labour• Material• Machine
Process Output• Design• Product• Buildings• Infrastructure
What do we do to get it done? How do we do it?
Planning
We leadProject Scheduling Objectives
• Estimating time of project by determining the earliest start and finish of each activity.
Finding the minimum cost schedule needed to complete the project by a certain date.
Investigating the results of possible delays in activity’s completion time.
Progress control
Smoothing out resource allocation over the duration of the project.
We leadProject Scheduling
• Tasks are called “activities.” - Estimated completion time (and sometimes costs) are associated with each activity.
- Activity completion time is related to the amount of resources committed to it.
- The degree of activity details depends on the application and how specific is the data.

Identifying the Activities of a Project
• To determine optimal schedules we need to– Identify all the project’s activities.
– Determine the precedence relations among activities.
We leadIdentifying Activities
• Example:
- Company A is a contractor & they need to
construct a house.
We leadIdentifying Activities
• Major task they need to perform & complete:
- Sub-structure
- Superstructure
- Internal Finishes
- Services and finishing
- External Works
We leadIdentifying Activities
• Company A needs to develop a precedence relations chart.
• The chart gives a concise set of tasks and their immediate predecessors.

From the activity description chart, we can determine immediate predecessors for each activity.
We leadScheduling Tools & Techniques
• Mathematical Analysis- calculating theoretical early and late start and finish dates for all projects activities without regard for any resource limitations.
- The resulting dates are not schedule, but it indicate the time period within which activity should be schedule.
We leadMathematical Analysis
• Critical Path Method (CPM)
• Graphical Evaluation and Review Techniques (GERT)
• Program Evaluation and Review Technique (PERT)
We leadScheduling Tools & Techniques
• Bar Charts- Milestone charts- Gantt charts
• Horizontal time scale is used, often divided into weeks.
• Various operations comprising the project are listed vertically down the left-hand side.
We leadBar Charts
• The timing and duration of each operation indicated by a horizontal bar spanning the relevant period of weeks and shown on the same line as the operation it refers to.
We leadProgress Report
• It is a document used for updating the progress of work.
• Can be in many forms i.e: report (short report, formal report), memo, letter, or presentation.
We lead
What is expected to be in progress report?
• Background of the project• Discussion of achievement during that period
of time (including the photos).• Discussion of the problems arise• Discussion on the work to be completed.• Current cost/budget• Assessment of whether you will meet the
objectives in the proposed schedule and budget
