should begin or and committing to do soPlanning processes-devising and maintaining a workable scheme to accomplish the business need that the project undertaken to addressExecuting processes-coordinating people and other resources to carry out the plan Controlling processes-ensuring that project objectives are met by monitoring and measuring progress and taking corrective action when necessaryClosing processes-formalizing acceptance of the project or phase and bringing it to an orderly endDec.2001Wanjun JIANG GSM PKUInitiating processThe formal initiating links the project to the ongoing work of the performing Org.Inputs:product description;strategic plan;project selection criteria;historical informationTools and techniques:project selection methods;expert

PKUPlanning is of major importance to a project because the project involves doing something which has not been done before.The processes above are subject to to frequent iterations prior to competing the plan.For example,if the initial completion date is unacceptable,project resources,cost,or even scope may need to be redefined.In addition,planning is not an exact science-two different teams could generate very different plans for the same project.Dec.2001Wanjun JIANG GSM PKUScope planning:developing a written scope statement as the basis for future project decisionsScope definition:subdividing the major project deliverables into smaller,or manageable componentsActivity definition:identifying the specific activities that must be performed to produce the various project deliverablesActivity sequencing:identifying and documenting interactivity dependenciesActivity duration estimating:estimating the number of work periods which will be needed to complete individual activitiesSchedule development:analyzing activity sequences,activity durations,and resource requirements to create the project schedule.Resource planning:determining what resources(people,equipment,materials)and what quantities of each should be used to perform project activities.Dec.2001Wanjun JIANG GSM PKUCost estimating:developing an approximation(estimate)of the costs resources needed to complete project activities.Cost budgeting:allocating the overall cost estimate to individual work itemsProject plan development:taking the results of other planning processes and putting them into a consistent,coherent document.Quality planning:identifying which quality standards are relevant to the project and determining how to satisfy themOrganization planning:identifying,documenting,and assigning project roles,responsibilities,and reporting relationshipsStaff acquisition:getting the HR needed assigned to and working on the project.Dec.2001Wanjun JIANG GSM PKUCommunication planning:determining the information and communications needs of the stakeholders:who needs what information,when will they need it,and how will it be given to them.Risk identification:determining which risks are likely to affect the project and documenting the characteristics of each.Risk quantification:evaluating risks and risk interactions to assess the range of possible project outcomesRisk response development:defining enhancement steps for opportunities and responses to threatsProcurement planning:determining what to procure and whenSolicitation planning:documenting product requirements and identifying potential sources.Dec.2001Wanjun JIANG GSM PKUExecuting processes Facilitating processesProject plan

project plan by performing the activities included therein.Scope verification:formalizing acceptance of the project scopeQuality assurance:evaluating overall project performance on the regular basis to provide confidence that the project will satisfy the relevant quality standard.Team development:developing individual and group skills to enhance project performanceInformation distribution:making needed information available to project stakeholders in timely mannerSolicitation:obtaining quotations,bids,offers,or proposal as appropriatesource selection:choosing from among potential sellerscontract administration:managing the relationship with the sellerDec.2001Wanjun JIANG GSM PKUControlling processesfacilitating processesPerformance reportingOverall changecontrolScope changecontrolSchedulecontrolRisk responsecontrolCostcontrolQualitycontrolDec.2001Wanjun JIANG GSM PKUProject performance must be measured regularly to identify variances from the plan.The variance are fed into the control process in the various knowledge areas.Overall change control:coordinating changes across the entire projectScope change control:controlling change to project scopeSchedule control:controlling changes to the project schedule Cost control:controlling changes to the project budgetQuality control:monitoring specific project results to determine if the comply with relevant quality standards and identifying ways to eliminate causes of unsatisfactory performancePerformance reporting:collecting and disseminating performance information,including status reporting,progress measurement,and forecastingRisk response control:responding to changes in risk over the course of the project.Dec.2001Wanjun JIANG GSM PKUClosing processes Contractclose-outAdministrativeclosureDec.2001Wanjun JIANG GSM PKUAdministration closure:generating,gathering,and disseminating information to formalize phase or project completionContract close-out:completion and settlement of the contract,including resolution of any open items.The process illustrated above meet the test of general acceptance-they apply to most projects most of time.However,not all of the processes will be needed on all projects,and not all of the interactions will apply to all projects.When there is a need to make change,the change should be clearly identified,carefully evaluated,and actively managed.Dec.2001Wanjun JIANG GSM PKUII.Project PlanningDec.2001Wanjun JIANG GSM PKUWhy do I need a P.O.D.?To provide a baseline of information for approval
