1 Project planning and execution 1

2 Step by step Mindmap WBS Network Resource worksheetGantt Resource diagram 2

3 What to consider when planning your project Hard issues: Deadlines and duration Well-defined goals (e.g. a prototype – a spec for a contract) & approvals of milestones/product deliverables Resources Risks Soft issues: Interfaces (both technical, organizational & human oriented) Conflicts Communication Commitment versus involvement 3

4 A Mindmap – a good place to start Create all issues that may be relevant

5 Work Breakdown Structure I Stepwise or gradually planning process. Structuring according to: Physical/geographical location Type of work Functions Systems Organisational belonging

6 Work Breakdown Structure II Use e.g. your function tree or mind –map to split your project tasks into even smaller tasks. Determine in which order you will solve the different tasks.

7 Example of a WBS

8 Network Diagrams – What and Why? Shows the sequences and relationship among tasks Time and work-oriented Reveals the workflow of a project as opposed to a WBS but says nothing about hierarchical relationships Good for scheduling and optimising the process (crash analysis) 8

9 Network diagrams – Rules  There can only be one start- and one stop activity  If there is more than one start or stop – a “empty start or stop” activity is developed  All activities must have a previous and future activity  An activity cannot be started until the previous one is finished  If the two activities overlap, they should be divided  Activities must not be connected in a circle  All activities are named or numbered  Earliest start date or a latest end date this is stated  Calculation is made forwards as well as backwards in the network. 9

10 Earliest start date Earliest finishing date Latest finishing date Latest start date Es Ef Ls Lf Tc B Tc = Duration of the activityB = Name of the activity Network diagrams Semantics of the network Usually plans are made backwards - usually you have a fixed time of delivery 10 Project planning and control

11 Network diagrams Estimation of duration Estimation can be based upon: –Experience -> Analogy –Calculations -> Break down –Process dependant and crash time (it takes the time it takes) –Different special estimation techniques dependant upon industry –Good argumentation and use of several estimation techniques normally gives a more valid estimate 11

17 The critical path Earliest finishing date is found by adding duration to start  The chain of activities that determine the duration of the project is called: critical path  Some activities can be shifted or prolonged without influencing the duration of the project – BUT not the critical path

19 Reduce duration of the network diagram - Preparation Determine extra costs when speeding up activities Determine crash time of each activity (minimum time needed) Determine critical activities

20 Guidelines for reducing time Reduce the duration of critical activities according to the following guidelines –First Speed up the activity with the lowest extra costs, then the activity with the second lowest costs etc.. Until one of the below criteria is met: The desired duration is obtained The amount allocated for speeding up purposes has been spent Watch OUT!! The critical path changes!!!

And what does it cost?

Note that time ”bought free” do not equal days saved

30 Gantt Chart Remember to be true to the purpose of the Gantt chart e.g. visualization or detailed planning Where the network diagram gives you a overview over dependencies and flow of the project. Gannt chart provides you with an overview over time and activities Analyse & use a network diagram for creation of Gantt Charts Group activities in relation to work content and type of resources (e.g. Departments) Decide upon milestones 30

31 Gantt Chart The Gantt chart may indicate the following: Duration of activity Time available Time performed Slack time Resource Milestones Activity dependencies 31

32 Gantt chart 2 engineers 4 hours a day Time Activity name Time Time available/slack Milestone Critical path Progress (percent) 32

35 Risks management Identifying risks (risks, constraints) Prioritising risks (severity and probability) Developing plans for risk avoiding (proactive plan) Developing solutions and “work arounds” (response plan) Following up and managing risks (indicators) 35

36 Risks management Typical risks in real-life projects Funding -> E.g. get a lower amount of money than promised Time -> Get a shorter development time Staffing -> Can’t get the right people High performance team -> conflicts in team Customer relations -> customers don’t have the needed time to work with you Project size and task complexity Overall project structure e.g. In a political environment External factors -> E.g. new technology or new government 36

37 Risks management Risk -> naming the risk and potential impact on project Probability of risk will occur Severity if risk occur Pro-active risk avoiding plan – what can be done to avoid risk Response plan if risk occur Indicators – shows if the risk may occur Remember to: –Prioritise risks –Follow up upon prioritised risks 37

38 Risk management matrix RiskProbabilitySeverityPro-active action Response plan Indicators Lack of time High Severe – deadline must be kept Tight control of progress Work extra hours Various excuses from group- members 38

39 Workshop: Identifying risks for your project What are the risks for student projects? RiskProbabilitySeverityPro-active action Response Plan Indicators 39

40 To the next time Hand in preliminary project description – October 1rst (to your supervisor and upload to fronter) – –ALL 7 sections must be included ( including a Gantt chart) –For Gantt chart use Excell, MS project or other PM IT based tools –Approximately 10 pages –Everyone from the group must “deliver” and participate in the work
