3. Project Planning “The larger, more complex or uncertain an endeavour is, the more important planning becomes” Lockyer & Gordon What measures would you use to determine the complexity of a project?

4. Measures of Project Complexity

5. Why Plan? IS development is complex and time consuming There are usually a number of people involved with a project Communication –Informs Project Manager/Team of the state of the project –Customer confidence

6. Why Plan? Projects are unique and therefore there will always be uncertainties –Need to plan for these (Plan B) So… –For anything more than the smallest project, planning must be a formal process

7. Project Planning for IS Requires knowledge drawn from: –Development techniques –Application domain –Project planning techniques –Skills abilities and motivation of developers –Business and organisational environment

8. Project Proposals Project planning starts with the project proposal - Result of Conception Phase Maybe a response to a project brief –prepared by an external or internal customer

9. Project Initiation Project initiation document –Internal or external Project manager needs a good appreciation of requirements –This may require extra work Customer needs report on unknowns –protects both the project team and the customer

10. The Project Plan – Simple Form The project plan is an attempt to timetable all the activities that make up a project –How will the project be divided –Who does what –When are tasks carried out

11. The Project Plan More detail can be added to the plan to indicate: –Level of performance and quality –Costs Further detail indicates: –availability of the resources required to carry out each task

12. The Project Plan Summary plan –Shows key tasks, events and milestones in the systems project –Primarily used for reporting progress Detailed plan –Task plan –Time control plans –Resource plan –Cost plans –Primarily used as a working tool

13. Planning and Control Cycle

14. Iterative Process The plan will evolve as the project evolves The plan is reviewed and updated as more information becomes available and uncertainties become less uncertain

15. The Project Plan – Simple Form How will the project be divided? –Work breakdown structure –Product breakdown structure When will the work be carried out? –Gantt Chart Who does what?

16. Work Breakdown Structure Work broken down in a hierarchical manner until: –Each task is “atomic” –Duration can be estimated with reasonable accuracy –Can be carried out by one person Each task : –Has a well defined beginning and end –Will consume resources –May be dependant on other tasks

17. WBS Example

18. Product breakdown structure Concentrates on what is to be done, rather than how it is to be done More difficult to forget a product/element Easier to assign quality measures/procedures Process is more likely to fit if developed after product example

19. PBS Example

21. The Project Plan – Simple Form How will the project be divided? –Work breakdown structure When will the work be carried out? –Gantt Chart Who does what? How will the project be divided? –Work breakdown structure When will the work be carried out? –Gantt Chart Who does what?

22. Example Gantt chart

24. Gantt chart components An Activity/Task is represented as follows: The length of the bar is proportional to the duration time of the activity Start Finish

25. Gantt chart components Progress on an Activity/Task can be shown as follows: The length of the bar is proportional to the amount of work completed. This example is approx 50% complete Start Finish

26. Example Gantt chart

30. Gantt chart advantages It is good at showing timing It shows project progress clearly It is therefore an ideal tool for the summary plan

31. Gantt chart disadvantages Not ideal for showing inter-relationships –MS Project does do this Locating an activity requires three simultaneous decisions: –Method –Time –Resources

32. How will the project be divided? –Work breakdown structure When will the work be carried out? –Gantt Chart Who does what? The Project Plan – Simple Form How will the project be divided? –Work breakdown structure When will the work be carried out? –Gantt Chart Who does what?

33. The Cost of Planning Labour and associated expenses Planner's tools Cost of preparing the written plan Opportunity costs - what could those involved be doing if they weren't planning?

34. Benefits of Planning Avoids the cost of the chaos that would ensue if the project was unplanned Filters out projects that would provide a negative return Being able to resolve problems in advance Being able to allocate resources in advance

35. Two Views to a Plan The Plan is a straight-jacket –Very Precise –Focus on data The Plan is a working tool –Very Accurate –Focus on information

36. Who Does Planning Developing the project plan is an iterative process that involves: –Project manager –Project team –Project sponsor –Customer –Other stakeholders

37. Iterative Process The plan will evolve as the project evolves The plan is reviewed and updated as more information becomes available and uncertainties become less uncertain
