Continuous improvement
COVID-19
Logistics of delivering tests
Planning
Well defined objective
Unique
Temporary
Some degree of complexity
Uncertainty and risk
Project Management
Understand the project environment: social, economy, business, politics
Project definition: objectives, scope and strategy,
Project planning
Technical execution
Project Planning
Identify objectives
Estimate times and resources
Identify relationships and dependencies
Identify resource time constraints
Fix the schedule for time and resources
Network Analysis
Critical Path: the path with the longest duration of time. The project cannot be completed sooner than the time required by the critical path
Activity scheduling
Forward pass
Earliest Start (ES) = maximum EF of imm. predecessors
Earliest Finish (EF) = ES + activity duration
Backward pass
Latest Finish (LF) = minimum LS of immediate following activities
Latest Start (LS) = LF – activity duration
Program Eval
Determine the probability that the project will be completed within a certain time period [risk involved in the project
Most likely time (m), the Optimistic time (a), the Pessimistic time (b)
Use expected times to identify critical path, and compute slack and project time
Total project variance = Sum of variance of critical path activities
Project variance is a measure of the risk involved in the project
Crashing Project Networks
the process of reducing time spans on activities so that the project is completed in less time. This usually incurs extra cost
Focus must be on critical path activities
In order to decide which activity to crash, the ‘crash cost slope’ of each is calculated (crash cost per time period).
Crash the activity on the critical path which has the lowest crash cost slope.
