Material resources are materials consumed in the completion of a task, as opposed to equipment used to complete a task. When you assign a material resource, you specify the way the material is consumed. With variable material consumption, the quantity of material consumed changes as task duration changes. Examples of variable material consumption include the following:
• Fuel for a generator
• 3d mm film in a photo shoot or movie
• Disposable paint rollers
• Bottled gases used in welding
• Antibacterial scrub soap used in a surgical unit
Variable consumption resources are assigned at an amount per time period based on the material label listed for the resource (see Figure 10.8): 10 gallons per day (10 gal/d), 2 packs per hour (2 pk/h), 4 tons per month (4 ton/me),
Choosing the fixed material consumption method indicates that the amount of material used is not related to the duration of the task. Examples of fixed material consumption include the following:
• Topsoil in a landscaping project
• Deck boards and wood posts used to build a deck
• Squares of shingles and rolls of roofing nails used on a roof
• Primer, paint, or wallpaper used to paint a room
• 2 x 4 s used to frame a house
• Rivets and steel plate used to build a ship
Materials consumed in a fixed quantity, regardless of duration, are assigned without a time period: 10 gallons (10 gal), 2 packs (2 pk), 4 tons (4 ton). When you assign the material resource, Project calculates work: the total materials used in the task.
You can assign material resources from Gantt Chart view with or without the Task Form To assign material resources to a task in Gantt Chart view;
1. Switch to Gantt Chart view (View >- Gantt Chart).
2. Select the task(s) that you want to create the assignment for.
3. Click the Assign Resources button on the standard toolbar.
4. Select the material resource name in the Assign Resources dialog box.
5. To assign a fixed consumption resource, enter the number of units of the resource that wiII be used in the task. To assign a variable consumption resource, enter the number of units per unit of duration.
6. Click the Assign button to assign the resource.
The views you use to assign resources are task views. The Gantt Chart view, for example, displays tasks and the resources assigned to the tasks. Project 2000 also includes resource forms, so you can see resources and their tasks. The forms are used to review assignments from the point of view of the people assigned to them or to see where materials are used in the project. You can’t print the resource forms.
The Resource Usage view, which can be printed, combines a timeline with tasks grouped by resource to show the hours that the. resource is assigned to tasks each day.
Using the Resource Name Form
The Resource Name form displays limited information about tasks assigned to a resource. To display the Resource Name form, choose View More Views Resource Name to open the Resource Name form, shown in Figure 10.9. Double-click a task to open the Task Information form for the task. Use the Previous and Next buttons to move from resource to resource.
Using the Resource Form
The Resource Form, shown- in Figure 10.10, includes editable information fields for the resource, including standard, overtime, and per-use rates. Double-click a task to open the Task Information form for the task. Use the Previous and Next buttons to move from resource to resource.
Using the Resource Usage View
The Resource Usage View gives you an easy way to view each resource’s scheduled periodic activity. In this view, project tasks are grouped by resource, and resources are listed in alphabetical order. the Resource Usage view for the Decentralization Project used as an example in previous .
Unassigned tasks, if any, are listed at the top of the view. Click the Collapse button in front of a resource name to hide the list of tasks assigned to the resource. If assignment detail is hidden, click the Expand button to expand the view and display the resource’s assignments.
The total hours shown in the resource’s Work column is resource work.
The total hours of assignment for each time period are shown in the same row of the grid. Assignment hours allocated in the grid are called time scaled or time phased hours (see Figure 10.11). The resource’s assignments are listed under the resource. The total time that the resource is assigned to the work, assignment work, is shown in the Work column. Time-phased ‘hours for each assignment are displayed in the grid.
Applying a Different Rate Table to an Assignment
In Project 2000, you can enter up to five different rate tables for a resource, on the Costs tab of the Resource Information dialog box, shown here
Then you assign a resource, Project use, the rate torn Cost Rate Table A. To use-a tate from a different table for an assignment, double-click the assignment in the Resource Usage view to open the Assignment Information dialo., box, as shown in Figure 10.12.
On the General tab select the rate table you want to use from the drop-down list, and then click OK to apply the rate table.
When you make a resource assignment, Project uses the default flat work contour and spreads each unit’s effort evenly across the duration of the task. If, for example, a resource is assigned 100% to a 40-hour task with no predecessors, the task will begin immediately with 8 hours of work each day for 5 days. In Gantt Chart view, you can see a task’s duration.
However, you can’t see the detail showing how many hours of work will be completed each day within the duration. There are two views that show you how the work is distributed within an assignment: the Resource Usage view (refer to ) and the Task Usage view, shown in
The shape of the distribution of work within an assignment is the work contour. The work contour is not an attribute of the task or the resource; it is an attribute of the assignment. When the work is spread evenly, the contour is flat. The flat contour is appropriate when the same amount of wort, should be done every day of the assignment. With some assignments, this isn’t the case. Writing this book, for example required minimal work at the beginning (preparing an outline), followed by a huge amount of work (writing the text). The project then ramps down as editing continues, but initial writing has been completed .
You can change the distribution of an assignment’s work by applying a predefined contour. Or, you can edit the existing distribution or the distribution created when you applied a contour to create a custom contour.
