5 L U N D S U N I V E R S I T E T What is Project Time Management? Time Management: Includes the processes required to ensure timely completion Processes of Project Time Management: 1. Activity definition– identify the activities required 2. Activity Sequencing– identify interactivity dependencies 3. Activity Duration Estimating– estimate work periods 4. Schedule Development– analyze activity sequencing, durations, resource requirements to create schedule 5. Schedule Control– controlling changes to the project schedule

6 L U N D S U N I V E R S I T E T Tools and techniques Input: Work Breakdown Structure Scope Statement Historical Information Tools and Techniques: Arrow diagramming method Network templates Time and Resource Analysis Output: Project Schedule (Resource histogram) (Project Reports)

7 L U N D S U N I V E R S I T E T What is Planning? ”To forecast and describe future events”

8 L U N D S U N I V E R S I T E T What is Project Planning? Communication Basis for the Decision Process Schedule is a Project Map Identify Potential Problems

9 L U N D S U N I V E R S I T E T Basic Planning Terms TaskAssignment that consumes time and resources EventMomentarily. Consumes no time or resources LinkDescribes Relations Between Tasks (events) ResourcesAll Things Needed to Accomplish a Task

10 L U N D S U N I V E R S I T E T Task Duration and Work Duration: (days, weeks, month) The Time Span from Start to Finish Work: (man hours) The Amount of Time the Resource spends Working with the Task

11 L U N D S U N I V E R S I T E T Task “A” Duration 5 days add one Duration 2,5 days 1 Resource unit (100%) resource 2 Resource units (200%) Work 40 h unit Work 40 h Task - Effort Driven

12 L U N D S U N I V E R S I T E T Task - Not Effort Driven Task “B” Duration 5 days add one Duration 5 days 1 Resource unit (100%) resource 2 Resource units (200%) Work 40 h unit Work 80 h

13 L U N D S U N I V E R S I T E T Four Types of Links Finish to Start AB A B Start to Start A B Start to Finish A B Finish to Finish

14 L U N D S U N I V E R S I T E T Type of Networks "Activity on arrow"-method and "Activity on node"-method. Which of the methods is the best, is often discussed.

15 L U N D S U N I V E R S I T E T "Activity on arrow" is event oriented Network Items –Events –Tasks –Links Activity on arrow

16 L U N D S U N I V E R S I T E T Activity on Node “The Activity on node” is Task oriented Network Items  Tasks (Events)  Links 5 days A 8 days B 6 days C 11 days D 10 days E

20 L U N D S U N I V E R S I T E T Analysing Networks - Time Analysis ”Forward” calculation - from left to right to calculate Early dates ”Backward” calculation- from right to left to calculate Late dates A BC E D

21 L U N D S U N I V E R S I T E T Critical Path The sequence of tasks, events and dependencies that determines the early finish date of a network. A delay of a task on the critical path will delay the whole network.

22 L U N D S U N I V E R S I T E T Total and Free Float Total Float:The time a task may be moved without delaying the network. Free Float:The time a task may be moved without delaying any other task.

27 L U N D S U N I V E R S I T E T Time and Resource Analysis Time analysis is automatically performed by MS Project - calculates project duration - identifies the critical path and task float - resource availability is not considered Resource Analysis is performed on command - based on time analysis - consider available resources - manage resource overallocation

31 L U N D S U N I V E R S I T E T Progress Control Why tracking project progress? Identify deviations from the baseline Updated on the project status Prognoses on actual duration and costs Correcting actions

32 L U N D S U N I V E R S I T E T What information are followed-up? Task:Resource: - actual start- actual work - Work complete (% of total)- remaining work - remaining duration- actual costs - actual finish- remaining costs
