6. Why does project management methodology matter?
15/02/2017
Varying versions exist but cartoon seems to have been documented first in John Oakland's book Total Quality Management.
7. Project Planning and Control
15/02/2017
Develop Work
Breakdown Structure
Define resources, costs,
and durations
Schedule work packages
using network logic
Team consensus on
baseline cost-loaded
schedule
Plan
Track progress against
the baseline
Analyze Earned Value
metrics
Corrective action and
change management
Do – Check – Assess
8. The Work Breakdown Structure (WBS)
A deliverables-oriented decomposition of the work to be
executed by the project team to accomplish project objectives
and create the desired deliverables with each descending level
representing an increasingly detailed definition of the project
work
Deliverable: Any measurable, tangible or verifiable item that
must be produced to complete a project
In Practical Terms
The WBS is what to deliver
It is a fundamental tool to properly manage
the project scope
9. Common language for all team members
Defines and outlines scope

10. Determine the Resources and Quantity of Resources Required
for Work Packages

11. Shows how changes in one task impact other tasks
Facilitates scheduling (and rescheduling) of people and equipment
Promotes analysis of tradeoffs and potential corrective action

Early warning system
• Early corrective action – cost/schedule variance correction
• Scope management – change orders for new scope
18. WBS Best Practices
15/02/2017
The names of the WBS elements should be easy to understand and
convey meaning to all project participants and stakeholders
The work packages should account for 2 to 10% of the total project
budget (exceptions can occur for very large or very small projects)
Activities or should not have durations beyond two project reporting
periods
Do not use the same task heading for activities performed by two
separately responsible groups
Include task and/or work packages in the WBS for work that will
performed outside parties, even if they do not involve a cost
(regulatory review, peer assists)
Break down items such as permits, regularly scheduled field events
and reports into their component activities
19. Whenever possible obtain estimates from individuals who have
performed similar activities in past
Have people who are responsible for performing a given task
provide duration estimates
Make all estimates realistic. It is best to consider most likely
amount of time needed, without a pessimistic or optimistic view
In general assume a normal workweek and normal workday
Use days as the time unit
Be willing to breakdown into smaller WBS elements if there is
difficulty in estimating the duration of a particular activity
Do not assume that office workers will have 8 hours of
uninterrupted time. Assume that office workers are 70%
productive and adjust durations accordingly
Duration Estimating Best Practices
15/02/2017
20. Do not link Summary Tasks
PM and Oversight tasks
Start when project starts and finishes when the last activity finishes
Set Constraints as little as possible
Instead, consider using Deadlines as they do not directly affect project
scheduling dates
For risk modeling you should not have any “must start” , “must finish or
similar constraints
Maximize concurrency whenever possible
Multiple finish to start activities off a given milestone
Use of start to start logic connectors
Minimize discretionary dependencies
Network Scheduling Best Practices

22. Site Background Information
Former specialty petroleum manufacturing facility
Objective to prepare site for sale and use as mixed
commercial / residential redevelopment
Project scope of work includes
Removing and properly disposing of asbestos and regulated wastes from
manufacturing plant
Demolishing the building structure
Excavating and properly disposing of soil having concentrations above
residential standards
Dewatering during excavation and discharging water to a publically owned
treatment works
Obtaining all necessary permits prior to performing field activities
Business plan called for completing project by September
30, 2011 at cost of $4.6 million
23. Risk Elements included in Model Structure
Probabilistic cost and duration input parameters
Probabilistic resource assignments (i.e. employs
RiskProjectResouceUse function) and resource unit prices
Durations for Level of effort or “hammock task” such as
project management or driven by the uncertain duration
of other tasks and network logic
Project risk register to address low probability high impact
events (i.e., makes use of RiskProjectAddDelay function)
24. General Notes on Environmental Remediation Projects
Notorious for going over budget and schedule
One of the largest uncertainties is always associated with
the volume of impacted material (soil, sediments) that
must be addressed
Another large source of uncertainty is permitting and
regulatory approvals.
The percentage of cost for project management higher
than in other construction industries
Project carrying costs can be high

32. Actual Results
Project was completed for a cost of $ 4.9 Million and in
May of 2012
Soil volume was 20% greater than planned
The selected contractor had an injury even at another site
which created a stop work order at this site
33. Summary Cost Schedule Risk Analysis
Powerful tool for communicating potential cost and
schedule outcomes
Enhances ability to identify and manage cost and schedule
drivers
Simplifies estimating cost trends and improves net
present value analysis
Opens the door for probabilistic earned value analysis –
control chart approach
CSRA should remain dynamic and re-visited throughout
project life cycle
