Managing Projects Chapter 14 Chapter Objectives Be able to: Explain the difference between routine business activities and projects Describe the five major phases of a project Construct a Gantt chart and interpret the results Construct a project network diagram and calculate the earliest and latest start and finish times for all activities Identify the critical activities and paths in a network Crash a project Copyright © 2013 Pearson Education, Inc publishing as Prentice Hall 14 - Project  Project – A temporary endeavor undertaken to create a unique product, service, or result © 2008 Project Management Institute  Projects have clear starting and ending points after which the people and resources dedicated to the project are reassigned  Projects are non-routine, can be large or small, and may be difficult to manage  Projects typically require significant levels of crossfunctional and interorganizational coordination Copyright © 2013 Pearson Education, Inc publishing as Prentice Hall 14 - Project Management  Project Management – The application of knowledge, skills, tools, and techniques to project activities to meet project requirements © 2008 Project Management Institute Copyright © 2013 Pearson Education, Inc publishing as Prentice Hall 14 - Project Management Trends  The faster pace of strategic change  New product lines are introduced more often to fight off competitors  Information technology solutions become quickly out-ofdate  Customer and supplier networks quickly change  The changing role of middle management  The role has decreased due to more advanced information systems handling many of the tasks  Responsibilities given to middle managers have been pushed down to supervisors and employees Copyright © 2013 Pearson Education, Inc publishing as Prentice Hall 14 - Project Phases      Concept phase Project definition phase Planning phase Performance phase Postcompletion phase Figure 14.1 Copyright © 2013 Pearson Education, Inc publishing as Prentice Hall 14 - Project Phases  Concept Phase  Broad definition and scope  Budget estimates within  30%  Project definition Phase  Tentative schedules and budgets, organization, key personnel and resource requirements  Budget estimates refined within  5% to 10% Copyright © 2013 Pearson Education, Inc publishing as Prentice Hall 14 - Project Phases  Planning phase  Detailed plans, timing, budgets and resources  Milestones  Project management tools and techniques  Performance phase  Execution and control  Postcompletion phase  “Wrap-up”  Reassignment of project resources Copyright © 2013 Pearson Education, Inc publishing as Prentice Hall 14 - Project Management Tools  Gantt charts – Graphical tools used to show expected start and end times for project activities and to track actual progress against these time targets  Network diagrams – Graphical tools that show the logical linkages between activities in a project Copyright © 2013 Pearson Education, Inc publishing as Prentice Hall 14 - Gantt Charts Table 14.2 Activities can occur simultaneously and some have predecessors that must be completed beforehand Copyright © 2013 Pearson Education, Inc publishing as Prentice Hall 14 - 10 AON Example – Gina 3000 Table 14.3 Calculate Earliest Start and Earliest Finish Times Copyright © 2013 Pearson Education, Inc publishing as Prentice Hall 14 - 19 AON Example – Gina 3000 Table 14.4 Calculate Latest Start and Latest Finish Times Copyright © 2013 Pearson Education, Inc publishing as Prentice Hall 14 - 20 AON Example – Gina 3000  Identify the Critical Path(s)         ACFGJ = 13 weeks ACDEGJ = 17 weeks ACDEHJ = 17 weeks ACDEIJ = 17 weeks BCFGJ = 14 weeks BCDEGJ = 18 weeks BCDEHJ = 18 weeks BCDEIJ = 18 weeks The activities in these critical paths have no slack The project should be completed in 18 weeks Copyright © 2013 Pearson Education, Inc publishing as Prentice Hall 14 - 21 Crashing a Project  Crashing a Project – Shortening the overall duration of a project by reducing the time it takes to perform certain activities  List all network paths and their current lengths and mark all activities that can be crashed  Focus on the critical path or paths Working one period at a time, choose the activity or activities that will shorten all critical paths at the least cost The one rule is this: Never shorten an activity that is not on a critical path, regardless of the cost Doing so will not shorten the project; it will only add costs  Recalculate the lengths of all paths and repeat step until the target project completion is reached or until all options have been exhausted Copyright © 2013 Pearson Education, Inc publishing as Prentice Hall 14 - 22 Crashing Example 14.3 Courter Corporation  Use the following data to develop a schedule to complete the project within 23 weeks: Table 14.5 Copyright © 2013 Pearson Education, Inc publishing as Prentice Hall 14 - 23 Crashing Example 14.3 Courter Corporation  Network Diagram: Figure 14.6 Copyright © 2013 Pearson Education, Inc publishing as Prentice Hall 14 - 24 Crashing Example 14.3 Courter Corporation  Calculate ES, EF, LS, and LF for each activity * Critical Activity Note: Critical Activities have a Slack = Table 14.6 Copyright © 2013 Pearson Education, Inc publishing as Prentice Hall 14 - 25 Crashing Example 14.3 Courter Corporation  Network Paths for the Project  ABEFGK – 25 weeks  ACDFGK – 24 weeks  AHIJ – 19 weeks Copyright © 2013 Pearson Education, Inc publishing as Prentice Hall 14 - 26 Crashing Example 14.3 Courter Corporation  Choose the activity(s) that will shorten all critical path(s) at the least cost:  ABEFGK – 25 weeks • Activity B - shorten week at a cost of $500 Copyright © 2013 Pearson Education, Inc publishing as Prentice Hall 14 - 27 Crashing Example 14.3 Courter Corporation  Updated Network Paths for the Project  ABEFGK – 24 weeks  ACDFGK – 24 weeks  AHIJ – 19 weeks  Crashing cost: $500 Copyright © 2013 Pearson Education, Inc publishing as Prentice Hall 14 - 28 Crashing Example 14.3 Courter Corporation  Choose the activity(s) that will shorten all critical path(s) at the least cost:  ABEFGK – 24 weeks  ACDFGK – 24 weeks • Activity G - shorten week at a cost of $700 Copyright © 2013 Pearson Education, Inc publishing as Prentice Hall 14 - 29 Crashing Example 14.3 Courter Corporation  Updated Network Paths for the Project  ABEFGK – 23 weeks  ACDFGK – 23 weeks  AHIJ – 19 weeks  Crashing Cost = $500 + $700 = $1200 Copyright © 2013 Pearson Education, Inc publishing as Prentice Hall 14 - 30 Project Management Resources  Project Management Software  Microsoft Project  PMI (Project Management Institute)  Sponsors education and certification  Sponsors conferences, research, user groups  Publishes Guide to the Project Management Body of Knowledge (PMBOK®)  PMBOK®  Part I: Various business processes for projects  Part II: Nine project management knowledge areas Copyright © 2013 Pearson Education, Inc publishing as Prentice Hall 14 - 31 Managing Projects Case Study Viva Roma!
