On Complexity…… Dealing with complexity is an inefficient and unnecessary waste of time, attention and mental energy. There is never any justification for things being complex when they could be simple. Edward de Bono
Project Management 101 ‘What Isn’t Measured Isn’t Controlled’ ‘Just Because You’re Measuring Something Doesn’t Mean You’re Managing It’
10 TRUTHS FOR CRITICAL PATH MANAGEMENT • Time is our enemy and he never rests or goes on vacation • Bad things happen ……….. so better be prepared • Time travel machines do not exist • Never take a hit now if you can defer it to later • Hide the fat • It’s riskier to bring a project ahead than have it run late • Don’t believe everything you’re told • Control the bow wave before it washes out your outage • If you haven’t got time to do it right, when will you find time to do it over? • The die is cast by Day 6
When Bad Things Happen Risk Management Process • Minimize impact of discovery work on: • safety and • outage schedule
Basic Principles • Anticipate problems: • Unfavourable results from: • 1st time projects • Inspections & tests • Infrequently performed work • Critical system components • Known problem areas • Plan for “what if” scenarios
Strategies for Managing Risk • Avoidance • De-scope • Modifying the activity • Additional resources • Adding time to the schedule Reduction • Add redundancy • Order spare parts • Outsourcing • Additional oversight Acceptance
Risk Assessment • Risk = Probability x Consequences • Assess each “what if” scenario against a risk matrix • Determine the level of contingency planning required
Use Challenge Reviews • Purpose: Challenge and test readiness of each department to execute outage within targets • Objective: • Awareness of scope, schedule and targets • Confirm parts and equipment adequate • Understand what could go wrong and contingencies in-place to handle them
Schedule Contingency • Management Reserve concept • Have contingency for crushing the bow wave • Front end load risky activities
Rapid Trending • Goal: Early identification & addressing adverse safety conditions • or trends • 22 areas monitored • (ex. Ergonomics, Falling Objects, Hand Safety & Hearing Protection) • Daily field observations rate areas as ‘safe’ or ‘at risk’ • During outage, analyzed for emerging adverse trends • As areas fall below targets ‘adverse’ conditions are reported to Management and corrective actions taken.

30 Minute Rule • Employees are to elevate work delays • Every employee should resolve problems themselves but when unable within 30 minutes their line supervisor is contacted • Supervisor immediately resolves problem or contacts the Outage Control Center • For critical path work, OCC representative is contacted immediately • 1 Hour Rule • Employees must know who has the next activity in the work sequence. • FLM of the work group to be contacted at least one hour before task will be finished • For critical path work, the OCC and the work group with the next activity "must" be contacted one hour before task is finished.
Getting Better Corrective Action Program • Ensures deficiencies that adversely impact plant operations, personnel safety, environment or equipment reliability, are promptly identified and corrected • Includes non-conformances, weaknesses with a process, document, or service • Captures information at all levels • Record cannot be deleted
Corrective Action Plans • Allows learning from mistakes • Prevents repeat occurrences by • Evaluating the problem to determine root cause • Identifying the solution and actions required • Evaluating the effectiveness of corrective action taken

March 11, 2011 • The Fukushima nuclear facilities were damaged in a magnitude 8.9 earthquake centered offshore of the Sendai region, which contains the capital Tokyo. • Plant designed for magnitude 8.2 earthquake. An 8.9 magnitude quake is 7 times in greater in magnitude. • Serious secondary effects followed including a significant tsunami, significant aftershocks and a major fire at a fossil fuel installation.
