Chapter 9: Resourcing Projects.This chapter demonstrates how to schedule resources on projects: determining the need for workers, understanding who is available, and assigning people. All of the techniques of resourcing projects are integrated with the behavioral aspects of how to deal effectively and ethically with the people involved. Resource needs are shown on a Gantt chart developed in Chapter 8, the responsibilities are shown as they change over time, conflicts and overloads are identified, and methods for resolving conflicts are introduced. Alternative approaches for creating and compressing schedules are shown. Many of the techniques in this chapter are also shown with MS Project.After completing this chapter, each student should be able to perform the following:Core Objectives:
- Show resource assignments on a RACI chart, Gantt chart, and resource histogram.
- Develop an effective project schedule, considering resource constraints.
- Describe methods of resolving resource overloads.
Behavioral Objectives:
- Create a Human Resources Management Plan including role descriptions and staffing management plan.
- Assign roles and responsibilities based on strengths.
Technical Objectives:
- Compress a project schedule using crashing and fast tracking, and describe the advantages and disadvantages of both.
- Compare various alternative scheduling methods.
- Using MS Project, assign resources, pinpoint overloads, and describe methods of dealing with them.
Chapter 10: Budgeting Projects.This chapter discusses the project budget, which is dependent on both the schedule and the resource needs developed in the previous two chapters. The project budget is the sum of work package cost estimates, contingency reserve, and management reserve. Cost planning, estimating, budgeting, establishing cost control, and using MS Project for project budgets are all included.After completing this chapter, each student should be able to perform the following:Core Objectives:
- Define project cost terms and tell how each is used in estimating project cost.
- Compare and contrast analogous, parametric, and bottom-up methods of estimating cost.
- Create a time-phased, bottom-up budget for a project.
Technical Objectives:
- Show both summary and bottom-up project budget information with cumulative costs using MS Project.
Behavioral Objectives:
- Describe issues in project cost estimating and how to deal with each.
Reflection and Discussion Forum Week 5
Reflection and Discussion Forum Week 5Reflect on the assigned readings for the week. Identify what you thought was the most important concept(s), method(s), term(s), and/or any other thing that you felt was worthy of your understanding.
Also, provide a graduate-level response to each of the following questions:
- Describe a potential timing issue that can occur early in a project and a potential timing issue that can occur at the end of a project. How would you address each of these issues in your project?
- Compare a project you’ve worked on that was limited mostly by activities with another project you’ve worked on that was limited mostly by resources. Which did you find more challenging? Why?
- You are the project manager in charge of construction of a new school building. Give one possible example each of a known known, known unknown, and unknown unknown you might encounter.
- Give an example of how a project manager could run into problems with cash flow, even when he is within budget on the overall project.
[Your initial post should be based upon the assigned reading for the week, so the textbook should be a source listed in your reference section and cited within the body of the text. Other sources are not required but feel free to use them if they aid in your discussion]. [Your initial post should be at least 450+ words and in APA format (including Times New Roman with font size 12 and double spaced). Post the actual body of your paper in the discussion thread then attach a Word version of the paper for APA review]

Methods of Resolving Resource Overloads
Reorder activities
Acquire or borrow additional resources
Reduce project scope or extend project schedule
Inform sponsor of severe overloads
Resource- level the overloaded person’s schedule
Assign certain activities to other workers
Split an activity into two activities
Perform 1st part as scheduled
Delay 2nd part of activity

Resource Leveling
Delay activities so person doesn’t perform as many activities at the same time (most common)
Delay noncritical activities by an amount no more than their slack
Allow project to slip
If non-critical activities must be completed at rate of effort in original schedule, reassign activities to another worker
Resource leveling is a combination of art & science
Resource Leveling – a project execution technique of adjusting the use of resources based on availability and the amount of float on activities to accomplish work as soon as possible, given the limited resource availability.

Compress the project schedule
Crashing may cost more money to speed up the schedule
Fast tracking may increase the risk to speed up the schedule
In agile, crashing is called “swarming,” since team members swarm on a problem to help get back on track
Crashing – speeding up the critical path often by adding additional resources or employing existing resources for longer hours and/or more days per week
Fast Tracking – a method to expedite a project by executing activities at the same time that would ordinarily be done one after the other

If there is a bonus of $225 per day for finishing early, what would I crash and how fast would I get done?
Crashing Consideration Questions
How fast can the project be completed?
To crash the project one day, what activity would be crashed and what would it cost?
To crash the project two days, what activities would be crashed and what would it cost in total?
If there is a bonus of $125 per day for finishing early, what would I crash and how fast would I get done?

5. Dealing with Over- Allocations
MS Project good at identifying over-allocations, but PM is responsible for deciding how to deal with them
Each action has risks and may “break” something down the line
Protect your critical path!!!
© 2019 Cengage Learning. All Rights Reserved. May not be copied, scanned, or duplicated, in whole or in part, except for use as permitted in a license distributed with a certain product or service or otherwise on a password-protected website for classroom use.
Some choices for dealing with Over-Allocations:
Replace over-allocated resource with one that has time for assignment
Reduce Units assignment, extending activity duration
Lessen scope of one or more activities
Ignore overload if resource impact is temporary
Try Resource Tab>>Level Group>>Level Resource or Level All & see how timeline is affected

6. Crashing a Critical Path Activity
Crashing adds resources to a task to shorten time
Only makes sense to “crash” tasks on critical path
Crashing is just one option & not appropriate in all cases

Summary
PM needs to look at listed activities & estimate resources needed to perform each.
Resource assignments often posted directly on a Gantt Chart schedule.
RACI charts depict work activities on a vertical scale
Use responsibility histograms to determine overloads
Use critical path schedule, resource assignments, & the resource histogram to determine who is overloaded, when, & by what activities.
Use resource leveling to reduce peak demands by postponing non-critical activities

Summary
Look for methods of accelerating (compressing) the project schedule.
Crashing—decision to pay extra money to speed up certain activities on critical path
Fast tracking—allows activities normally conducted in sequence to be performed in parallel
Alternative scheduling methods:
Critical chain
Reverse phase
Rolling wave
Agile
Auto/manual
Project scheduling software such as Microsoft Project 2016 is useful when determining resources for a project.

Methods of Estimating Costs
Timothy J. Kloppenborg
“I worked for the same company in both cities…. Both [methods] made sense where they were used. In Denver, if we wanted to bid every job (and you cannot win the job if you do not bid on it), we needed a fast method. In Kansas City, we had the time to develop detailed cost estimates, and so we took the time. There are many methods of estimating project costs and each has its place.”

Direct vs. Indirect Costs
Direct costs only occur because of project
Direct labor
Other direct costs – material, travel, consultants, subcontracts, purchased parts, computer time
Indirect costs – not associated with one specific project
Salaries, buildings, utilities, insurance…
Costs are allocated across projects
PM needs to understand how these costs are allocated

Recurring vs. Nonrecurring Costs
Recurring costs repeat as project work continues
i.e. Cost of writing code or laying bricks
Occur most during project execution
Nonrecurring costs happen only once during a project
Design development
Generally occur during project planning & closing
© 2019 Cengage Learning. All Rights Reserved. May not be copied, scanned, or duplicated, in whole or in part, except for use as permitted in a license distributed with a certain product or service or otherwise on a password-protected website for classroom use.
Regular vs. Expedited Costs
Regular costs preferred
Expedited costs occur when the project must be sped up
Overtime, expedited shipping, etc.
Vital to understand schedule pressures & resource demands when estimating costs

Other Cost Classifications
Project estimates need to be aggressive
But add a reserve to cover activities that run over estimates
Estimate – “a quantified assessment of the likely amount…It should always include an indication of accuracy.” ~Practice Standard for Project Estimating (PMI)
Reserve – extra money in project budget to be used if necessary—usually if a risk event occurs…classified as either management reserve or contingency reserve.
© 2019 Cengage Learning. All Rights Reserved. May not be copied, scanned, or duplicated, in whole or in part, except for use as permitted in a license distributed with a certain product or service or otherwise on a password-protected website for classroom use.
Two types of Reserve Costs
Management reserve – money assigned to the project for unknown possible costs & money that senior management controls.
Contingency reserve – money assigned to the project & allocated for identified risks for which contingency responses are developed.
