Resource Product Concept: A resource product ( ) is the result of work time a time-based resource ( ) spends, using material based resources ( ) in an activity ( ), and the result of the amount of work for this resource in the activity is measured by the need for this resource to produce a certain amount of the product, therefore measured with a material unit of measure, where the resource product is the result of the amount of work done by resources working in the activity, and the combination of the resource efforts will result in a material product. The idea is to compensate using man-hours to calculate time based resources effort, and use resource product amounts to calculate the required time for a resource to finish an activity. Work, duration, and performance: Performance is the number of hours a time based resource is able to produce in a time period, in the Resource Product, performance is defined as the amount of work that a time based resource can produce in a time period. =

Brick wall example: A worker uses cement, bricks, and sand to build a wall, and he spends a considerable amount of time on the activity, the resource product of this resource is the brick wall. Measured in longitudinal meters with a constant height, the worker produces 2 meters of this wall per hour, and the worker's work hours for a day are 10. Therefore when we apply the performance equation: =
=
10 ℎ
∴ =
1 2 × 10
= 10 ℎ, ,
=
= 2/ / ℎ

From a practitioner's practitioner's point of view, applying this concept will be helpful in measuring resource performance based on work quantities, and this will be applied using scheduling software Primavera P6 Project Management Module. Primavera P6 Project Management Module: When working a project in Primavera P6 PM, you'll enter resources to the program in 3 steps:
1st Step: Apply Resources Requirements Analysis planning process (according to PMBOK project management (PMBOK Guide)—Fourth Guide)—Fourth Edition. process groups) A Guide to the Project Management B ody of Knowledge (PMBOK ®
2nd Step: Enter and organize resources in Primavera P6 PM Resources Screen, and define resource details: ID, Name, Type, Performance (Default Units/Time, Max Units/Time), Calendar, Price/Unit.

3rd Step: Assign resource to activity from Activities screen, Activity Details, Resources tab, and after that enter amount of work required from the resource in Budgeted Units column.
Our focus will be on step 2: 1. In choosing the resource type, we have: Labor (time-based for worker), Non-labor (time-based for machines), and Material (non-time-based for materials), here our brick worker will be a material resource 2. When applying the change, the Unit of Measure field is activated to choose a unit of measure for this resource, and the unit of measure we need to choose is the unit of measure for the resource product. 3. The performance fields (Default Units/Time, Max Units/Time), are filled out according to the performance equation. 4. The Price/Unit field will contain the price the worker charges for one unit of the final product, where our brick worker here charges 1 USD/m. After applying the previous guidelines, step 3 will require the total amount of work to complete this project according to the resource product concept, and to complete the example, let us say that the total length of our wall will be 200 meters.

Practice: When applied, this concept facilitated conveying a construction project's Bill of Quantities into Primavera P6 PM, and working through resources to prepare work invoices based on BofQ items. Also when applied, the concept made following resource productivity easier then charging them by the hour, and time-based hours that had no work in them were easy to see, and fix. Advanced research: The concept is approved to work theoretically and practically, and under development research, to support the concept of Resource Product and to replace time-based concept.
