Throughout a project, changes may occur that have an impact on the schedule. As was notedearlier, these changes might be initiated by the customer or the project team, or they might be theresult of an unanticipated occurrence. Here are some examples of changes initiated by thecustomer:A home buyer tells the builder that the family room should be larger, and the bedroomwindows should be relocated.A customer tells the project team developing an information system that the system musthave the capability to produce a previously unmentioned set of reports and graphics, whichrequires additional new elements in the database.These types of changes represent revisions to the original project scope and will have an impacton the schedule and budget. The degree of impact, however, may depend on when the changes arerequested. If they are requested early in the project, they may have less impact on schedule andbudget than if they are requested later in the project. For example, changing the size of the familyroom and relocating the bedroom windows would be relatively easy if the house was still beingdesigned and the drawings being prepared. However, if the changes are requested after theframing is put up and the windows are installed, the impact on schedule and budget will be muchgreater.When the customer requests a change, the contractor or project team should estimate the impacton the project schedule and budget and then obtain customer approvalbeforeproceeding. If thecustomer approves the proposed revisions to the project schedule and budget, then any additionalactivities, revised estimated durations, and revised estimated resources and associated costsshould be incorporated into the project schedule and budget.An example of a change initiated by a project team is the decision by a team that is planning acommunity festival to eliminate all amusement rides for adults because of space limitations andinsurance costs. The project plan would then have to be revised to delete or modify all thoseactivities involving adult rides. An example of a change initiated by a project manager would be,rather than develop customized software for an automated invoicing component of a system, touse standard available software to reduce costs and accelerate the schedule.Some changes involve the addition of activities that may have been overlooked when the originalplan was developed. For example, the project team may have forgotten to include activitiesassociated with developing training materials and conducting training for a new informationsystem. Or the customer or contractor may have failed to include the installation of gutters anddownspouts in the work scope for the construction of a restaurant.Other changes become necessary because of unanticipated occurrences, such as a snowstorm thatslows down construction of a building, the failure of a new product to pass quality tests, or theuntimely resignation of a key member of a project team. These events will have an impact on theschedule and/or budget and will require that the project plan be modified.
