What is Project Management? Project management is “the application of knowledge, skills, tools and techniques to project activities to meet project requirements. ” Project management is accomplished through the appropriate application and integration of the project management process groups. These process groups consist of: • Initiating, • Planning, • Executing, • Monitoring and Controlling, and • Closing. *PMI, A Guide to the Project Management Body of Knowledge, (PMBOK® Guide) (2004), p. 8. Prof. M. El_Sherbiny
Cost & Staffing level in Project Life Cycle Prof. M. El_Sherbiny
Project Management Framework Prof. M. El_Sherbiny
Nine Project Management Knowledge Areas • Knowledge areas describe the key competencies that project managers must develop. – Four core knowledge areas lead to specific project objectives (scope, time, cost, and quality). – Four facilitating knowledge areas are the means through which the project objectives are achieved (human resources, communication, risk, and procurement management). – One knowledge area (project integration management) affects and is affected by all of the other knowledge areas. – All knowledge areas are important!

Develop Project Charter (DPC) ﺑﻨﺎﺀﻭﺛﺎﺋﻖﺍﻟﻤﺸﺮﻭﻉ • DPC is the process of developing a document that formally authorizes a project or a phase and documenting initial requirements that satisfy the stakeholder’s needs and expectations. • The charter links the project to the ongoing work of the organization and authorizes the project. • Projects are chartered and authorized external to the project by the organization, a program or portfolio management body. • In multi-phase projects, this process is used to validate or refine the decisions made during the previous iteration of DPC. Prof. M. El_Sherbiny
Project Stakeholders • Stakeholders are the people involved in or affected by project activities. • Stakeholders include: – Project sponsor – Project manager – Project team – Support staff – Customers – Users – Suppliers – Opponents to the project Prof. M. El_Sherbiny
Identify Stakeholder Input Output Prof. M. El_Sherbiny
Prof. M. El_Sherbiny
Project Management Tools and Techniques • Project management tools and techniques assist project managers and their teams in various aspects of project management. • Specific tools and techniques include: – Project charters, scope statements, and WBS (scope). – Gantt charts, network diagrams, critical path analyses, critical chain scheduling (time). – Cost estimates and earned value management (cost). Prof. M. El_Sherbiny
Advantages of Using Formal Project Management • Better control of financial, physical, and human resources. • Improved customer relations. • Shorter development times. • Lower costs. • Higher quality and increased reliability. • Higher profit margins. • Improved productivity. • Better internal coordination. • Higher worker morale (less stress).

Cost Form Calculations P 3 bases calculations in the Cost form on the following equations: Percent Expended = Actual Cost to Date/Budgeted Cost to Complete = Cost at Completion - Actual Cost to Date Earned Value = Percent Complete x Budgeted Cost Variance = Budgeted Cost - Cost at Completion Prof. M. El_Sherbiny
Budget Summary Calculations ﺣﺴﺎﺑﺎﺕﺍﻟﻤﻴﺰﺍﻧﻴﺔ ﻣﻠﺨﺺ Actual Quantity to Date = Budget x Percent Complete Actual Cost to Date = Actual Quantity to Date x Price/Unit Quantity to Complete = Rem Duration x Units/Time period Cost to Complete = Quantity to Complete x Price/Unit Estimate at Completion = Variance = Estimate to Complete + Actual to Date Budget - Estimate at Completion Prof. M. El_Sherbiny
Budget Summary Calculations ﺣﺴﺎﺑﺎﺕﺍﻟﻤﻴﺰﺍﻧﻴﺔ ﻣﻠﺨﺺ The Budget Summary form also shows the scheduled budget or budgeted cost for work scheduled (BCWS) and a quantitative earned value or budgeted cost for work performed (BCWP). ¨ P 3 calculates the BCWS only if you established a Target 1 schedule. You must also have updated the current schedule and the data date. Scheduled Budget (BCWS) = Target 1 Budget x Percent Complete Earned Value (BCWP) = Budget x Percent Complete Prof. M. El_Sherbiny
Project Management Budgeting, Cost Estimation and Project Cost Control Prof. Mahmoud El_Sherbiny Prof. M. El_Sherbiny
Project Budget • A Budget is a plan for allocating resources. • A Project Budget is a financial picture of the project plan • A budget (schedule) is a control mechanism. – A standard for comparison – Actual expenditures (schedules) are compared to the planned expenditures(schedules) – Variances are analyzed to • forecast future deviations • take corrective action Prof. M. El_Sherbiny
Project Budget • To develop a budget the following need to be forecasted: – what resources will the project need? – In what quantities? – When will they be needed? – How much will they cost? Prof. M. El_Sherbiny
How are budgets constructed? • Top-Down Budgeting – start with estimates of overall project cost and the costs of major sub-projects – to the lowest level in WBS • Bottom-up Budgeting – start with the lowest level in WBS and aggregate upwards – to reach the overall project budget • Iterative Budgeting Process Prof. M. El_Sherbiny

Steps in Establishing Project Control • Establish a plan: budgets, schedules, performance requirements • Measure results (actuals) and assess deviations from the original project plan • Report results to the appropriate project personnel and managers • Forecast the results of any deviations: analyze impact on project progress • Take corrective action: major replanning may be necessary. . Prof. M. El_Sherbiny
Earned Value Analysis (EVA) EVA • is a technique for tracking cost deviations and progress in a project. • Compares the budgeted costs with actual costs incurred throughout the project. • Also compares cumulative actual costs, incurred up to a given date, with the estimated cost of project work actually completed for any specified period of time • has an ultimate purpose of estimating, as accurately as possible, the final cost of the project. Prof. M. El_Sherbiny
Definitions • Budgeted Cost for the Work Scheduled (BCWS): – prepared at the planning phase – represents the estimate against which actual expenses are compared – BCWS is done for each activity, then aggregated to reach one final BCWS for the project. • Budget at Completion (BAC): – total planned project cost • Time at Completion (TAC): – the planned makespan of the project Prof. M. El_Sherbiny
Definition (Cont. ) • Actual Cost of Work Performed (ACWP): – calculated periodically (weekly, monthly etc. ) – ACWP for individual tasks are determined, then aggregated to obtain the ACWP for the project • IF ACWP < BCWS, “Under budget ? ? ” • Budgeted Cost of Work Performed (BCWP): – planned(budgeted) cost of the work “actually performed” – done for individual tasks and aggregated to obtain the project’s BCWP. Prof. M. El_Sherbiny
COST WORK Prof. M. El_Sherbiny
Variance Analysis • Cost Variance (CV) – CV = BCWP - ACWP • CV>0 • CV<0 project is “under budget” project is “over budget” • Schedule Variance (SV) – SV = BCWP - BCWS • SV > 0 project is “ahead of schedule” • SV < 0 project is “behind schedule. ” It will take approximately $SV to catch up. • Time Variance (TV) – TV = STWP - ATWP • TV>0 • TV<0 project is “ahead of schedule” project is “delayed” Prof. M. El_Sherbiny
Variances are also expressed in terms of ratios • Cost Performance Index: CPI = BCWP/ACWP • Schedule Performance Index: SPI = BCWP/BCWS • Time Performance Index: TPI= STWP/ATWP • Cost-Schedule Index: CSI = (CPI)(SPI) • CSI <1 is indicative of a problem. Prof. M. El_Sherbiny

EXAMPLE • At the end of a given reporting period, tasks A, B, C, D and E were planned to be completed. The planned costs to complete each task were determined to be: – A: $10, 000 – B: $35, 000 – C: $47, 000 – D: $28, 000 – E: $22, 000 • A, B and C were completed and D and E were not started. • Actual costs to complete A, B and C turned out to be $100, 000. Prof. M. El_Sherbiny
• BCWS = 10, 000+35, 000+47, 000+28, 000+22, 000 = $142, 000 • ACWP = $100, 000 • BCWP = BC(A) + BC(B) + BC(C) = 10, 000+35, 000+47, 000 = $92, 000 • CV = BCWP - ACWP = 92, 000 - 100, 000 = -$8, 000 The project is $8, 000 over budget. • CPI = BCWP/ACWP = 92, 000/100, 000 = 0. 92 • SV = BCWP - BCWS = 92, 000 - 142, 000 = -$50, 000 The project is $50, 000 behind schedule. It would take approximately $50, 000 to catch up. • SPI = BCWP /BCWS = 92, 000/142, 000 = 0. 65 • CSI = (CPI) (SPI) = (0. 92)(0. 65) = 0. 598 Prof. M. El_Sherbiny
Level 1 Level 3 Level 2 Level 4 Prof. M. El_Sherbiny
• Each period (month) the PM should receive the BCWS, BCWP, ACWP for each level 2 task in WBS • Each level 2 manager receives these from level 3 managers and so on. • Periodically each level receives a “Cost Schedule Status Report” – – BCWS, BCWP, ACWP, CV, SV, BAC, TAC and Estimated Cost to Complete (ECT) Estimated Cost at Completion (ECAC) Estimated Time at Completion (ETAC) – variances of the above (budget and time) Prof. M. El_Sherbiny
• ECT, ECAC and ETAC are estimated periodically to help the PM determine the impact of slippages • ECT = (BAC-BCWP)/CPI • ECAC = (ACWP/BCWP) x BAC = BAC/CPI = ECT+ ACWP – – in the previous example assume BAC = $1. 2 M ECT = (1, 200, 000 - 92, 000)/0. 92 = 1. 204 M ECAC = (100, 000/92, 000) $1. 2 M = $1. 304 M we are over spending • ETAC =(BCWS/BCWP) x TAC – in the previous example assume TAC = 50 weeks – ETAC = (142, 000/92, 000) x 50 = 77 weeks – we are behind schedule Prof. M.
