Relationship between scope schedule and budget

Build the Schedule and Budget

relationship between scope schedule and budget

As an added example, if the schedule appears to be tight and the scope to a project or accepting a budget cut without taking the effort to. That's why no project plan is complete until you come up with a budget. . your completed project, there would be additional cost and a change to the scope, The schedule variance (SV) is the difference between the earned value (EV) and . The relationship between scope & the golden triangle of quality, schedule, and budget is arguably the most important thing a PM has to manage on a project.

In a sense, these are the four things that have to be defined and documented, and then constantly balanced and traded off with each other during the course of a project.

Specifically, he says that he wants to increase the size of the detached garage from 2-cars to 3-cars. What are you going to do? Your job as a project manager is to calculate how much those increases will be, what their impact and risks are, and then get formal approval from the customer before implementing them.

You probably also need to identify ways of minimizing the impact of the scope increase. For instance, you might be able to absorb some or all of the additional cost by reducing the level of quality on some of the delivered scope.

Changing from expensive Italian marble flooring, for instance, to less expensive wall-to-wall carpeting could potentially save enough to pay for the larger garage. Another common problem you might encounter is a customer asking for a faster delivery of the product. Instead of 9 months to build the house, the customer might come to you a few months into the project and ask that it be delivered in a month early.

ETERNAL Constraints - The Project Management Triangle

Or, you might need to reduce the overall scope; e. Again, all four things scope, quality, schedule, and budget can often be balanced and traded off against each other in an effort to find the best overall solution. For example, reducing budget puts pressure on the other three items, and vice versa.

In other words, when making trade-offs and balancing between the constraints, you might have flexibility in changing only one or two of the constraints, but not the others.

Cost[ edit ] To develop an approximation of a project cost depends on several variables including: Tools used in cost are, risk managementcost contingencycost escalationand indirect costs. But beyond this basic accounting approach to fixed and variable costs, the economic cost that must be considered includes worker skill and productivity which is calculated using various project cost estimate tools.

This is important when companies hire temporary or contract employees or outsource work.

Cost Process Areas[ edit ] Cost Estimating is an approximation of the cost of all resources needed to complete activities. Cost budgeting aggregating the estimated costs of resources, work packages and activities to establish a cost baseline.
