									        Project Management
What is Project Management?
  Tracking project timing and cost.
  Managing project resources (people, materials, budget).

Why do Project Management?

  To monitor if your project is staying on time and
  is within budget.
  To ensure project goals are met.
          Project Management
What questions might project managers be interested in?

• How long will the project take?
• Can I add manpower or tools to reduce the overall project
length?
• To which tasks should I add manpower?
• What tasks are on the critical path?
• Is the project on schedule?
• When should materials and personnel be in place to begin a
task?
• Am I within budget?
• Should I transfer funds between line items?
• Other?…
Project Management - Examples
•   University Convocation Center
•   Windsor Engine Plant
•   Other major construction projects
•   Large defense contracts
•   NASA projects (space shuttle)
•   Maintenance planning of oil refineries, power plants, etc…
•   Senior Design projects
•   other…
 Project Management - Timing
Timing
A project consists of a series of tasks with estimated durations.

Consider building a house:
Step A: Prepare site. (5 days)
Step B: Build foundation. (8 days)
Step C: Frame walls and roof. (15 days)
Step D: Rough in Plumbing (12 days)
Step E: Rough in Electrical (10 days)
Step F: HVAC Venting (8 days)
Step G: Drywall (11 days)
Step H: Finish Electrical (5 days)
Step I: Finish Plumbing (4 days) Step M: Paint (5 days)
Step J: Finish HVAC (2 days)       Step N: Landscape (5 days)
Step K: Install Kitchen (8 days)
Step L: Install Baths (14 days)
 Project Management - Timing
Timing – Gantt Chart
Tasks and task durations are often represented as Gantt Charts.
No consideration for task precedence.
 Project Management - Timing
Timing – Network Diagram
Tasks must sometimes be performed in series, or may at times
be performed in parallel.

For the house example, let each arc represent a project task/job.

                                     D,12          H,5     7         J,2        M,5
                                                               K,8
      A,5       B,8       C,15                  G,11       0
                                     E,10                                             11

                                                           0
                                                                   L,14         N,5
                                     F,8           I,4     8
Each arc is identified by a job letter and duration. Note the
dummy jobs indicating precedence that jobs H and I must
complete before K or L begins.

With task precedence knowledge.

Why is knowing the critical important?
  Project Management - Cost
Costs

Estimate your costs by task (add a safety
factor, 20-50%?), also called itemizing.

Track your costs by item.

Formally transfer/track transfer of budget
between line items.

Stay within budget!!
Project Management - Resources
 Resources

 How do resources effect project management?

 • Add workers to reduce task time.
 • Remove workers if a task is not on critical
 path.
 • Ensure tools and supplies are available at
 start of each task.
 • Other?

Manual Method

Can you manage projects manually?

Absolutely, who managed the building of the
Egyptian pyramids and what software did they
use?

I have used Excel to “manually” track projects.
 Applying Project Management
Initial Setup
• Identify task and task precedence
• Estimate task cost and timing
• Identify critical path
• Modify resource allocation to adjust task timing and
costs

Continuous Monitoring
• Update if timing has changed
• Identify if still on time
• Identify if critical path has shifted
• Modify costs as “real” costs are realized

Products – 4.6L, 5.4L, 6.8L Ford Truck Engines
Location – Windsor, Ont.
Budget - $1.2 billion

Project Management – 1 person dedicated to timing,
Primavera software, Gantt charts hung around “war
room”, cost management by individual team
managers (with “help” from Finance dept.).
Applying Project Management
Personal Experience – Windsor Engine Plant

My Responsibilities – team manager of information
systems and communications (PCs, networks, phones,
pagers, radios, computer room, PFIS, etc…)

Timing Tracking Method – Used Excel (problem
deck), White Board (primary projects), and note pad
(to do list).
Problem Deck – Some projects tracked closely some
loosely dependent on who was lead analyst.
Primary project status – updated weekly.
To do list – updated daily.

Cost Tracking Method - $8million budget, itemized
by primary projects (e.g. PCs, Networks, Radios,
Computer Room, etc…).
Used Excel and reports from Finance office to track
line items, monitored on a weekly or bi-monthly basis
