12/6/2007 Project Scheduling and Tracking 2
Agenda
• Project Scheduling
– work breakdown and task definition
– task dependency (PERT) analysis
– milestones and Earned Value Analysis
– resource and staffing dependencies
– time lines (Gantt Charts)
– staffing levels (PNR curves)
• Project Status Tracking
– Using EVA to measure progress
• Automated Scheduling tools

Project Scheduling
decompose project into
distinct tasks and subtasks
establish dependency
relationships among sub-tasks
estimate the size of, and work to
accomplish each sub-task
identify or define
project milestones
characterize the required
resources for each sub-task
identify available resources
assign dates to initial tasks
assign resources to tasks
acceptable
yes

Work Breakdown
• hierarchical decomposition of work
– independent sub-tasks that sum to the whole
– can be based on either tasks or goals
– both process- and problem-centric
• sub-tasks are fundamental unit of work
– the granularity of work estimation
– the granularity of assignment & scheduling
– the granularity of task inter-dependencies
– the basis for progress tracking
• granularity will evolve with the project

Task Dependencies
• input/output relationships between tasks
– may be strict
• e.g. system test starts after component integration
– may allow overlap
• e.g. design can start one month after architecture
• process-mandated pre-requisites
– support training must precede beta shipment
• these dictate the order of scheduling
– they also determine the (longest) critical path

Establish Project Milestones
• Specific and Measurable
– an objectively ascertainable moment
– avoid subjective assessments
• Relevant measures of project progress
– goals achieved, work completed
– not merely hours of work done
• Timely (relatively closely spaced)
– enable fine-grained progress tracking
– accurate assessment of work state and rate
