1. Project Management

2. Projects „Unique, one-time operations designed to accomplish a specific set of objectives in a limited time frame.”

3. Processes in an organization Usual business processes Projects Changes & Uncertainty Routines & regular tasks

4. Main characteristics of projects Uniqe set of tasks and processes Narrow focus, specific performance objectives The end of the project is definite: –Limited time-frame –Objectives reached or –it is proven, that objectives cannot be reached anymore Budget is limited It can be planned It is always risky

5. Project management Project management is the discipline of planning, organizing, and managing resources to bring about the successful completion of specific project goals and objectives. Project-like management: managing non- project processes as projects

6. Project Manager (Stevenson) Responsible for: Work (tasks)Quality Human ResourcesTime CommunicationsCosts

7. Other roles in the project Project-coordinator: negotiate with the functional leaders, report to the project manager Project champion: strong person who promotes and supports the project Projectmanagement-team members Project-workers: deliver the tasks

8. Project Life Cycle (Stevenson) Concept Feasibility Planning Execution Termination Management

9. Project life cycle

11. Cost of changing in the life cycle Planning, preparation Definintion Implementation, execution Closing the project Time Costs Influence of the stakeholders Cost of changing

12. Project-management tools

13. Problem tree diagram A problem tree is a problem analysis tool that illustrates the cause and effect relationship of problems using a hierarchical tree diagram. by arranging the problem statements in hierarchical order and depicting the problem statements in a boxed article.

14. Problem-tree

15. Fishbone (Ishikawa) diagram A Fishbone Diagram is a problem analysis tool that illustrates the cause and effect relationships of problems and is often use in the quality management discipline.

16. Objective tree An objective tree is an objective formulation tool that depicts graphically the hierarchy of objectives. It is formulated by initially inverting the statements found in the problem tree (often used in tandem).

17. Logical Framework Matrix Pre-conditions 4. Activities (inputs) 3. Outputs (results) 2. Immediate objective 1. Startegic goal 4. Risks and assumptions 3. Means of verifi- cation2. Indicators 1. Objectives- structure

18. Work Breakdown Structure a tool used to define and group a project's discrete work elements (or tasks) in a way that helps organize and define the total work scope of the project

19. GANTT charts A Gantt chart is a type of bar chart that illustrates a project schedule. Gantt charts illustrate the start and finish dates of the terminal elements and summary elements of a project. Some Gantt charts also show the dependency relationships between activities. Gantt charts can be used to show current schedule status using percent-complete shadings, or colored lines and a vertical "TODAY" line.

24. The Network Diagram Network (precedence) diagram Activity-on-arrow (AOA) Activity-on-node (AON) Activities Events

25. The Network Diagram Path –Sequence of activities that leads from the starting node to the finishing node Critical path –The longest path; determines expected project duration Critical activities –Activities on the critical path Slack –Allowable slippage for path; the difference the length of path and the length of critical path

37. Problem: converting table data to AoA and AoN ActivityImmediate predecessor Duration a-2 ba3 cb2 db1 TPT = ? Float = ?

38. Solution (AoN) Solution (AoA) a2a2 b3b3 c2c2 d1d1 finish star t 1 2 2a2a 3 2c2c 4 5 3b3b 1d1d

39. Solution: TPT from critical path analysis Identify all the paths and their duration: a-b-c = 7 a-b-d = 6 The path with the longest duration is the critical path, and it sets the TPT = 7 Identify the floats: The non-critical activities have floats. Here the only non- critical is the d. Its float is the time that it can use up without increasing the TPT. This time it is: 7 – 6 = 1
