This comprehensive guide delves into the essentials of Schedule Development for project managers. It covers fundamental concepts such as activity definition, sequencing, resource estimation, and scheduling methodologies like the Critical Path and Critical Chain methods. Learn how to set realistic deadlines, adapt to changing scopes, and mitigate risks while managing your project's timeline. With practical tips, best practices, and insights into tools like PERT, this resource is invaluable for ensuring your project remains on track and achieves its goals.

Schedule Development 101 How to create a schedule you can use
Project Management Proverbs • You can con a sucker into committing to an impossible deadline, but you cannot con him into meeting it. • Nothing is impossible for the person who doesn't have to do it. • If you're 6 months late on a milestone due next week but nevertheless really believe you can make it, you're a project manager. • The sooner you get behind schedule, the more time you have to make it up. REMEMBER: SCHEDULING IS NOT AN EXACT PROCESS, IT IS PART ESTIMATION, PART PREDICTION AND PART EDUCATED GUESSING
Fundamentals Schedule Development 101 (Chapter 6 Project Time Management) • Define Activities • What actions need to be performed to meet your project deliverables • Terms such as Decomposition, Rolling Wave Planning and Expert Judgment • Output: Activity List, Milestone List • Sequence Your Activities • Documenting the relationship among the project activities • Precedence Diagramming Method • FS, FF, SS, SF • Dependency Determination • Mandatory dependencies • Must be put in place • Discretionary Dependencies • Like to be put in place • External Dependencies • Something required that is outside of my control (delivery of hardware)
Fundamentals Schedule Development 101 (Chapter 6 Project Time Management) • Estimate Activity resources • Estimate the type and quantities of material, people, equipment or supplies required • Tools: Expert Judgment, Published Estimating Data • Estimate Activity durations • How long will it take to complete the activity by the resource • Tools: Analogous Estimating (similar project) or Three Point Estimates (PERT) • Most likely, optimistic and pessimistic
Fundamentals Schedule Development 101 (Chapter 6 Project Time Management) • Develop your schedule • Process of analyzing activity sequences, durations, resource requirements and schedule constraints to create a project schedule. • Tools: • Critical Path Method • Determine the late and early start and finish dates • Critical Chain Method • Modifies the project schedule to account for limited resources • Monitor and Control your schedule • Process of monitoring the status of the project against what you baselined • Status Reports • Change Requests
Real World Schedule Development 101 • Unrealistic Schedules—End Date • Constant changes in scope • Scope not defined or “locked” • Resource allocation changes • Resources reallocated to other projects
13 Suggestions you can useto make your schedules better • Use WBS to create a task list each element of the project scope must be supported by activity or activities • Get resource estimates on each WBS element and resource names • Allocate your resources appropriately • Establish Project and Resource Calendars • DO NOT DIRECT SCHEDULE TASKS use activity sequencing • Define your milestones • At a minimum each schedule should have a start and a finish milestones • Use your start milestone as your project dependency
13 Suggestions you can use to make your schedules better • Know your float values both Total and Free • Once you baseline do not touch Start and Finish Use Actual Start and Actual Finish • BASELINE BASELINEBASELINE • Utilize baseline 1 • Do not use auto level • Use PERT at all times and for all estimates • Use consistent project plan update methodology • Use the status date to status your project—How can do work if time has passed
PERT (Program Evaluation and Review Technique) Discussion • Most Plans have one estimate • PERT is based upon three estimates • Pessimistic everything goes wrong • Optimistic the sun the moon and the stars align and everything went right • Most Likely I won’t win a million dollars but I will win 10.00 (what will happen given normal problems and opportunities • Formula • (O+4M+P)/6
Schedule Inputs • Project and Personal Calendars • Working days, shifts, vacations • % Allocation • Project Risks • Understand what risks you have so you can understand if you have time in the schedule to deal with them • Activities and Resources requirements • What are the activities • What resources are required to complete the activities • What is the duration of the activity • Project Start or Project Finish Date • Milestones
Oh No—My Schedule is wrong what can I doTools to get you back on Track • Crashing and Fast Tracking • Change Requests • Rebaseline your plan • Critical Path Analysis—understand you Free and Total Float • Calculates the earliest and the latest possible start and finish times for a project

PMI-SP Exam • PMI-SP credential is a response to project management increasing growth, complexity and diversity. This certification fills the need for a specialist role in project scheduling • Myths • You do not need to be PMP certified to take the PMI-SP Exam • The certification references Microsoft project • If I am PMP certified then I have to increase the number of PDU’s for my PMI-SP certification
