Lesson 3 Flashcards
It is the process of identifying all the activities necessary to successfully complete the project. the heart of good project management
Project Planning
the process of determining the sequential order of the planned activities, assigning realistic durations to each activity, and determining the start and finish dates for each activity.
Project Scheduling
- Finish the project on time
- Continuous (uninterrupted) flow of work (no delays)
- Reduced amount of rework (least amount of changes)
- Minimize confusion and misunderstandings
- Increased knowledge of status of project by everyone
- Meaningful and timely reports to management
- You run the project instead of the project running you
- Knowledge of scheduled times of key parts of the project
- Knowledge of distribution of costs of the project
- Accountability of people, defined responsibility/authority
- Clear understanding of who does what, when, and how much
- Integration of all work to ensure a quality project for the owner
Sample Project Planning Steps
what are the 3 linked components
scope, budget, and schedule.
Developed by Henry L. Gantt
It is a graphical time-scale of the schedule.
It does not require special technical knowledge to be understood.
Each activity is presented by a bar that presents the activity duration.
Dependency between activities can be presented by vertical lines.
Present part of the overall program (weekly, monthly)
Bar charts are good for the planning and scheduling of simple and small projects but are not suitable for complex and large-scale projects.
BAR CHART OR GANTT CHART
Developed by DuPont Company in 1956
A network-based technique to facilitate the planning and scheduling of complex and/or large-scale projects.
It also eliminates the limitations of bar charts. The various activities of a project and the inter-dependencies among them are accurately and easily represented with the help of networks in CPM.
The plan of a project is represented in the form of a network and network calculations are used for the scheduling of a project.
Planning and scheduling are done separately.
Critical Path Method
rovides a comprehensive method for project planning, scheduling, and controlling.
network analysis system
Types of Network Analysis System:
Project Evaluation and Review Technique (PERT)
Critical Path Method (CPM)
a project management tool used to plan, schedule, and control complex projects
represented by nodes (events) and arrows (activities)
PERT
Optimistic Time (a): The minimum time required to complete the project, assuming everything goes better than expected.
Pessimistic Time (b): The maximum time required to complete the task, assuming things go wrong.
Most Likely Time (m): The most likely time required to complete the tasks, assuming everything goes alright.
tO BE CONSIDERED IN PERT
used to determine the earliest possible starting time for each task in the project. It’ll also help a project manager determine the critical tasks and non-critical tasks. This helps when executing the project.
CPM
Types of CPM diagram
Arrow diagram
Precedence Diagram
The main difference is that PERT is a visual technique, while CPM is a statistical technique.
2. CPM is used to control cost and time, and PERT is a must for controlling time when planning.
3. PERT uses a three-point method to forecast time, while CPM only has one measure for estimating.
