Title: Data, information, knowledge, wisdom before and after the event
1Project Management
- Data, information, knowledge, wisdom (before and
after the event) - Theory from Practice
- Updated from the lecture to better explain
- backward pass to determine latest finish of
preceding activities. - identification of critical path using LS-ES-D0
i.e. no slack or float time
2Overview
- a project - as a large scale, one-off operation
- identifying objectives deciding trade-offs
- imagining, planning, estimating, modelliing and
control - methods of scheduling
- networks of time and precedence
- Gantt chart and CPA methods
- Resource planning and management
- Limitations of project management concepts

4Project Management 2000
- project-based service organisations
- big projects and constant overspend
- corporate downsizing
- development of 3rd World former closed
economies - knowledge explosion buying in expertise
- global competition
- compression of product life cycle
- more customer focus

10Risk Analysis
What are the major risks for the
project? Probability of occurrence 0 --1
(high) Impact on project success if these risks
do occur? 0 -- 1 (high) Current project
status? Activity starts, completions,
in-progress, bottle-necks, delays, variation
orders, estimated expenditures vs. actual,
over-spends, under-spends, virement? Priority
team action? Interventions? Inspections/audits? Re
negotiations, variation orders, penalty clauses

16Shimmering, collaborative boundaries
- lead partner (Foster) engineers alliances (Arup)
- internal external - collect best-in-the-world competencies. bring a
specific, high quality product/service to market
ASAP - not one homogeneous orgn, but "BORG" hybrid e.g.
Sun - Mission accomplished
- disperse
- look for new alliances, opportunities
17Work Breakdown Structure - as a Hierarchy
Project
1 2 3 4 5 etc
End product - the deliverable
Sub- deliverables
Levels
Element (lowest level) deliverables
Cost-expenditures - estimates, assign
accounts Group work packages for monitoring
progress responsibility
Work package - identifiable work activities
18Work Breakdown Structure
Integrate this by level for coordination
control across organisation strategy, design,
manufacture, testing/quality, purchasing, IT
infrastructure (HWSWstaff), job/project
accounts (revenue spend), disbursement of
direct costs overheads

23Apportioning/Allocating Project Costs
24Generating the Project Plan - WBS
- Who is the project customer and project
stakeholders - Define
- end product or service (the specification) and
objectives - inputs total resources time required
- project organisation structure/network
- Identify and detail tasks/activities and
subtasks. If visible, group into phases. Enter
into Gantt Chart - Estimate enter durations of each task
- 1xPessimistic 4xLikely 1xOptimistic----------
--------------------------------------
6 - Decide before, parallel, after sequences
- Decide FS, SS, FF, FS relationships/dependencies
- Forward pass for project duration
- Backward pass for critical path and slack
- Load assign resources - physical and human to
tasks - Balance/level against cost time - baseline
budgets vs. actual

27Backward Pass for Latest times, critical path
slack
- start with last project activity(ies)
- from the project end activity, trace backward on
each path - subtracting (LF-Dur) activity times
to give the LS for each node - carry back the LS to the preceding node to
establish its LF unless - the preceding activity is a burst activity
(apredecessor to two or more activities) in this
case select the smallest LS from its immediate
successor activities to obtain its LF. - activity C in the next slide, is a burst
successor to E and F. Its LF depends on F i.e.
the lowest LS (20 not E's 185) - A, B, F, G, H are critical as LF-ES-Dur for each
is 0. There is no slack on these activities

36CPM Assumptions/Limitations
- activities can be identified as discrete
entities. - clear beginning ending point for each activity
- activity sequence relationships can be specified
networked. - project focus on critical path.
37Implementation and Control
- Monitor actual time, cost performance
- Data capture, reports/charts, progress,
exceptions - Compare plan to actual
- Is corrective action needed?
- Evaluate alternative corrective actions
- Take corrective action
- Data, capta, information, knowledge, wisdom
