Project Management Overview

What is Project Management?

  • Defined as a systemized, phased approach to:

    • Defining projects

    • Organizing tasks

    • Planning tasks

    • Monitoring progress

    • Controlling project activities

Definition of a Project

  • According to Project Management Institute, a project is:

    • A temporary endeavor undertaken to create a unique product, service, or result.

Major Characteristics of a Project:
  • Has an established objective.

  • Defined lifespan:

    • Every project has a beginning and an end.

  • Interdepartmental involvement:

    • Involves several departments and professionals.

  • Novelty:

    • Involves doing something not done before.

  • Specific requirements:

    • Has specific time, cost, and scope requirements.

Routine Work vs. Projects

Routine Work Characteristics:
  • Examples include:

    • Taking class notes

    • Daily accounting tasks

    • Responding to supply-chain requests

    • Practicing piano scales

    • Routine manufacturing tasks (e.g., manufacturing an iPhone)

Project Characteristics:
  • Examples include:

    • Writing a term paper

    • Setting up a sales kiosk

    • Developing a supply-chain information system

    • Writing new piano compositions

    • Designing a new electronic device (e.g., an iPhone interfacing with Apple Watch)

Examples of Project Types Given to Graduates:
  • Management Information System: Install new data security system.

  • Marketing Department: Execute a sales program.

  • Operations Management: Implement new store layout designs.

  • Accounting: Conduct audits on clients.

Project Management Trade-Offs

  • Project managers must manage three major criteria (trade-offs):

    • Cost (Budget)

    • Time (Schedule)

    • Scope (Performance)

Project Success Rates

  • Statistics indicate:

    • Software and hardware projects fail at a rate of 65%.

    • Over half of IT projects become runaway projects.

    • Only 30% of technology-based projects succeed.

    • Roughly 2.5% of global businesses achieve 100% project success.

    • Over 50% of global business projects fail.

  • Major causes of project failure:

    • Inadequate planning time

    • Underestimation of project duration

The Challenge of Project Management

Role of the Project Manager

  • Responsible for:

    • Project performance and success.

    • Being the direct link to the customer.

    • Providing direction, coordination, and integration to the project team.

    • Marshaling resources for the project.

    • Coordinating multiple departments within the organization.

    • Inducing the right team members at the right times for decision-making.

Purpose of Project Scheduling (Critical Path Method)

  • Objectives of project scheduling include:

    • Demonstrating the relationship of each activity to others and to the whole project.

    • Identifying precedence relationships among activities.

    • Encouraging realistic time and cost estimates for activities.

    • Making efficient use of people, materials, and budget by identifying critical bottlenecks in the project.

Developing the Project Network

  • Project Network Defined:

    • A graphic flow chart showing project activities, logical sequences, interdependencies, and estimated start and finish times.

    • Identifies critical path(s) which indicate project duration.

    • Highlights critical activities that should not be delayed.

Basic Rules for Developing Project Networks

  • Networks flow from left to right.

  • An activity cannot begin until all preceding activities are complete.

  • Arrows indicate precedence and flow; they can cross each other.

  • Common start and stop nodes may be utilized.

Precedence Relationships

  • Defining activity relationships:

    • Activities must be sequenced correctly to ensure proper undertaking.

    • Example configurations:

    • U cannot begin until S and T are complete; V cannot begin until T is finished.

    • S precedes T, which precedes U (ensure S and T complete before starting U).

Constructing a Project Network Terminology

  • Activity: An element of the project that requires time.

  • Merge Activity: An activity that has multiple preceding activities.

  • Burst Activity: An activity with more than one succeeding activity.

  • Parallel Activities (concurrent): Activities that can occur independently and do not need to occur simultaneously.

AON Fundamentals

  • The Activity-on-Node (AON) format illustrates activity precedence clearly, showing dependencies visually.

Total Time


25 Weeks

Definitions of Relevant Terms:
  • Earliest Start (ES): Earliest time an activity can start, assuming all predecessors are completed.

  • Earliest Finish (EF): Earliest time an activity can finish.

  • Latest Start (LS): Latest time an activity can start to not delay the entire project.

  • Latest Finish (LF): Latest time by which an activity must be finished to avoid delaying the project.

Activity Format and Scheduling Steps

  • Represent activity data clearly using:

    • ES

    • EF

    • LS

    • LF

    • Duration

  • Add activity times and propagate early finish to subsequent activities via network completion rules.

Forward Pass and Backward Pass Computation

  • Forward Pass: Calculates early start and early finish times starting from the beginning activity through to completion.

  • Backward Pass: Starts from the end activity and works backward to determine late start and late finish times; calculates slack time:

    • extSlack=LS−ESext{Slack} = LS - ES or extSlack=LF−EFext{Slack} = LF - EF

Gantt Charts

  • Use Gantt charts to visualize project timelines and the relationship between activities over the weeks.

Project Crashing

What is Project Crashing?

  • This is a method to expedite project completion while managing resources effectively. Introduction of crashing may affect all activity schedules and can introduce problems.

Rationale for Reducing Project Duration

  • Reasons include

    • Imposed deadlines

    • Unforeseen delays

    • Time to market pressures

    • Financial incentives for early completion

Cost-Time Tradeoffs in Project Crashing

  • Project Crashing involves shortening project durations; typically comes with increased costs, particularly for critical path activities.

  • Activities for crashing should be selected based on the smallest increase in cost per unit time.

Steps in Project Crashing

  • Identify critical paths and select activities with the smallest crash cost.

  • Update activity times and monitor if the adjusted due date/financial goals were achieved.

Challenges of Crashing

  • Unplanned issues may surface due to crashing.

  • The critical path can multiply as activities are adjusted, and marginal returns may diminish.

Conclusion

  • A comprehensive understanding of these methodologies and metrics is crucial for project management success.

  • Emphasize flexibility and adaptability in project approaches to enhance efficiency while managing risks effectively.
