Glossary for PCL

activity

The smallest part of the activity structure used for a time-scaled budget. An entity that is used to represent a part of a project in an activity structure.

Infor LN distinguishes these activity types:

  • WBS Element
  • Control Account
  • Work Package
  • Planning Package
  • Milestone

actual cost

The real costs incurred on a project. These costs are logged in Project Cost Ledger. For example, Inventory Cost, Purchase Invoice Cost, Price Variances, Manual Costs, and so on.

actual value

The costs incurred to accomplish the work performed within a given period.

apportion

To make a proportionate division or distribution for the earned value. When activity Y is apportioned to activity X, the earned value method of Y and X is the same. Y will copy X. X can have any earned value method.

baseline

The baseline is a snapshot of the active plan's scheduled activities start and end dates for a specific date and time.

commitment

A financial obligation that represents future costs.

control code

A common parent cost-object level, a level above the special cost object.

A control code is used for control purposes. For analysis, you can group cost objects of the same cost type under a control code. If you use a cost object to categorize a group of cost objects, it can be its own control code. You cannot have more than one control code in a tree. This is used for the frozen bottom-up budget.

cost component

A cost component is a collection of cost objects with a certain characteristic. A cost component does not depend on the cost type, therefore, for example, a project can be monitored from another dimension. For example, all the costs that refer to electrical work, for example, cable and installation work, are visible if the applicable cost objects are linked to the cost component Electrical work.

cost performance index

A measure of cost efficiency of a project.

The cost performance index (CPI) is determined by measuring the ratio of earned value (EV) to actual costs (AC):

CPI = EV / AC

If the result is less than 1.0, cost is greater than budgeted.

If the result is greater than 1.0, cost is less than budgeted.

example:

EV PV AC CPI SPI
270 335 250 1.08 0.81

earned value

The budget amount based on the project progress for a specific period.

earned value concept

A time-phased method for measuring project performance. It compares the amount of work that was planned with work that was actually accomplished to determine if cost and schedule performance are as planned.

There are a number of different ways in which you can use the earned value method to determine how budget amounts are to be earned:

  • Milestones

    Milestones are attached to the activity and a percentage or amount of the budget is assigned to each milestone. When you reach a milestone, the assigned budget is earned.

  • Start and End Percentage

    Percentage values are assigned to the start and end points of the activities. In other words, the start percentage is earned when the activity starts and the remaining percentage is earned when the activity is completed.

  • Percentage Completed

    Budget amounts are earned in proportion to the percentage progress of the activity.

  • Level of Effort

    Budget amounts are released in proportion to effort. This method is appropriate for time-driven activities where it is assumed that there will be no discrepancy between scheduled work planned (PV) and work performed (EV).

  • Apportioned

    Apportioned efforts are those which have an intrinsic performance relationship to some other discrete activity. Budget amounts are earned in the same way as for the linked activity.

estimate to complete

A realistic forecast appraisal of the remaining work.

estimate at completion

The forecasted total cost of a project, activity, or organization-breakdown-structure element when the defined scope of work is completed. To calculate the estimate at completion: actual costs + estimate to complete.

extension

The specific agreements within or in addition to the initial contract. An extension falls outside the initial contract with the sold-to business partner. Extensions can be assigned to the bottom-up budget.

Infor LN distinguishes these extension types:

  • Scope Change
  • Provisional Amount
  • Fluctuation Settlement
  • Quantities to be Settled

holdback

A percentage amount that the customer withholds from the contract amount. This serves as a guarantee that all activities are performed, and that contractual obligations are met. In other words the holdback amount is paid after the project activities have been satisfactorily performed.

level of effort

A budgeting method in which budget amounts are released in proportion to effort. This method is appropriate for time-driven activities where it is assumed that there is no discrepancy between work planned and work performed.

milestone

An activity of zero days that usually represents a significant event in the project. In many cases the completion of a phase of major deliverable. Milestones can be used for the moment of invoicing and the calculation of earned value.

organization breakdown structure

A representation of the structure of a project organization, this is usually depicted as a tree-like hierarchical structure. The organization breakdown structure is used to link the responsibilities of certain project parts, such as the allocation of a financial budget or the realization of project activities to an OBS element. Each OBS element can be linked to an employee. The OBS element is standard and can also be made project specific.

planned value

The planned budget amount for a specific period.

progress

The process by which an element or activity is completed over the lifetime of the project. Progress can be recorded at cost type, cost object, or at control code level.

project

An endeavor with a specific objective to be met within the prescribed time and financial limitation, and that has been assigned for definition or execution.

project currency

If the project is performed in another country, the project currency is useful for monitoring. This currency can be an external currency that is not specified as one of the home currencies.

schedule variance

Any difference between the scheduled completion of an activity and the actual completion of that activity.

schedule performance index

A measure of schedule efficiency of a project.

The schedule performance index (SPI) is determined by measuring the ratio of earned value (EV) to actual costs (AC):

SPI = EV / PV

If the result is less than 1.0, the project is behind schedule.

If the result is greater than 1.0, the project is ahead of schedule

example:

EV PV AC CPI SPI
270 335 250 1.08 0.81
