  2. Creating Order from Chaos What needs to be done? When? What to do first? Have you done everything? What comes next? InterWorks/UNHCR

  3. 6 Organigramme Management Tools • lists • diagrams • schedules • budgets • charts Gantt Chart Jan Feb Mar Apr May Jun Jul Aug assessment identify site contract survey contract water system contract food delivery purchase tents design camp layout set up logistics begin construction InterWorks/UNHCR

  4. PERT/CPM DIAGRAMS Boxes Lines InterWorks/UNHCR

  5. Boxes are TASKS Job InterWorks/UNHCR

  6. Lines are RELATIONSHIPS First Job Second Job InterWorks/UNHCR

  7. Task relationship 1 make soup find pot InterWorks/UNHCR

  8. Task relationship 2 find pot make soup find potatoes InterWorks/UNHCR

  9. Task relationship 3 peel potatoes find knife chop onions cut carrots InterWorks/UNHCR

  10. Task relationship 4 find vegetables peel potatoes find knife chop onions InterWorks/UNHCR

  11. Task relationship 5 order tents identify site start end InterWorks/UNHCR

  12. Logic Error 1-Looping transport people identify site deploy tents calculate tent deficit InterWorks/UNHCR

  13. Correction for looping transport people deploy tents deploy tents identify site calculate tent deficit InterWorks/UNHCR

  14. Logic error 2 - Dangling start identify site prepare budget contract labor finish survey site InterWorks/UNHCR

  15. Correction for Dangling start identify site prepare budget contract labor finish survey site InterWorks/UNHCR

  16. A control loop is something else.Don’t try to include one in this type of analysis. monitor progress implement revisions revise plan compare to plan decide on correctiveaction InterWorks/UNHCR

  17. REMEMBER! This technique is useful for things that have clear starting and ending points. Always include a start and a finish box in the diagram. A finish C start B InterWorks/UNHCR

  20. Task Duration Identify Site 5 how much time will it take? InterWorks/UNHCR

  21. 11 + 5 = 16 Task duration and schedule earliest start date earliest finish date 11 16 Identify Site 5 InterWorks/UNHCR

  22. 11 + 5 = 16 Looking Forward earliest start date earliest finish date 11 16 Identify Site 5 InterWorks/UNHCR

  23. 19 - 5 = 14 Looking back 11 16 Identify Site 5 14 19 latest start date latest finish date InterWorks/UNHCR
