GB520: Strategic Human Resource Management
Unit 5 Selection Methods Analysis
[Instructor Name]
[Date]
The contractor, the role and every figure are composite and illustrative; the validity estimates and sources cited are real.
The Role and the Current Method
Kestrel Refrigeration Services needs about eight commercial project managers over the next three years as it triples installations of carbon dioxide (CO2) refrigeration systems. A project manager runs several installations at once, each worth $1.5 million to $3 million. The role coordinates crews, equipment deliveries, electricians and the grocer's own contractors, and the date that matters most is the store's opening or reset. A project that slips by two weeks can cost Kestrel its liquidated damages, the crew's overtime and the customer's next job.
Kestrel currently selects project managers with an unstructured interview by the operations director and two reference calls. The last four hires produced one strong performer, two adequate ones and one who left after a project fell five weeks behind.
Table 1: Five Predictors Compared
General mental ability test. Validity: Schmidt and Hunter (1998) estimated a corrected validity of .51, but Sackett et al. (2022), correcting a long-standing overcorrection for range restriction, revised it to about .31. Adverse impact: the largest average group differences of the five. Cost: about $50 per candidate. Candidate reactions: often seen as unrelated to the job by experienced candidates.
Structured behavioral interview. Validity: about .42 in Sackett et al. (2022), at or near the top of the predictors they reviewed. Adverse impact: modest. Cost: about $400 per candidate for two trained interviewers' time. Reactions: generally favorable.
Schedule-recovery exercise. A work sample built from a real job: a supermarket remodel with a compressor rack arriving three weeks late, an electrical inspection that conflicts with the crew's schedule and a store opening fixed in the lease. The candidate has 90 minutes to produce a recovery plan and an email to the store's construction manager. Validity: about .33 for work samples. Adverse impact: moderate. Cost: about $900 per candidate, mostly the time of two assessors. Reactions: strongly favorable, because candidates see the job in it.
Conscientiousness inventory. Validity: about .19. Adverse impact: small. Cost: about $40. Reactions: mixed; some candidates find personality items intrusive.
Reference verification. Validity: about .26 in Schmidt and Hunter (1998), though structured reference questions about specific projects do better than general calls. Adverse impact: small. Cost: about $150. Reactions: neutral.
The predictor with the weakest record in Kestrel's own hiring, the unstructured interview, is the one the company relies on most.
Table 2: Fit With Kestrel's Constraints
Applicant pool. Kestrel can expect about 40 qualified applicants and 15 finalists for eight hires over three years. Every method that screens out qualified candidates for reasons unrelated to the job shrinks a small pool further.
Legal exposure. A method with large group differences invites a disparate impact challenge and must then be shown to be job related. The cognitive ability test carries the most exposure for the least added prediction once a work sample is in place, because the exercise already tests reasoning in the context of the job.
Candidate experience. Experienced project managers who are employed elsewhere can walk away from a process that feels generic. The schedule-recovery exercise and the structured interview both show candidates what the job demands, which also helps them decide whether to accept.
Cost. The recommended system would cost about $1,450 per finalist, against about $150 now.
The Recommended System
Use three predictors in sequence:
1. Structured interview for all qualified applicants. Six questions on past projects: recovering a late schedule, handling a customer's change order, managing a crew conflict, reporting bad news early, coordinating with an electrical subcontractor and keeping a safety standard under schedule pressure. Two interviewers rate every answer separately, using anchors that describe what a weak, an adequate and a strong account of a past project sounds like.
2. Schedule-recovery exercise for finalists. Scored by two assessors against a rubric covering sequencing, resource choices, communication and risk.
3. Structured reference verification for the top two candidates. Questions about the candidate's actual role on named projects.
The cognitive ability test is dropped because the exercise covers the same ground with less adverse impact and better candidate reactions. The conscientiousness inventory is dropped because its validity is low and its items add little that the structured interview's questions about reporting and follow-through do not already capture.
The Utility Estimate
The Brogden-Cronbach-Gleser model, described by Cascio et al. (2019), estimates the dollar gain from a better selection system as the number hired times their average tenure times the gain in validity times the dollar value of one standard deviation of performance times the average standardized score of those selected, less the added cost.
Hires (Ns): [8] over three years.
Average tenure (T): [5] years.
Validity of the current method: about [.25] for the unstructured interview and reference calls combined.
Validity of the new system: about [.48] for the structured interview and exercise combined.
Dollar value of one standard deviation of performance (SDy): [$60,000] a year, estimated from the spread in project margins between Kestrel's strongest and weakest project managers.
Selection ratio: about [one in five] finalists, giving an average standardized predictor score of about 1.40 for those hired.
Added cost: about [$61,000], including $25,000 to build the exercise and train assessors.
The estimate is 8 times 5 times 0.23 times $60,000 times 1.40, or about $772,800, less $61,000, for a gain of about $711,800 over the hires' tenure.
Utility estimates often overstate gains, because the inputs are uncertain and the model assumes every offer is accepted. A conservative version, with new validity of .40 and SDy of $40,000, still shows a gain of about $275,000. Either figure is large against the cost because a project manager's decisions move millions of dollars of work.
Risks and Monitoring
The exercise must be maintained: if candidates share its details, it loses value, so Kestrel should rotate two or three versions. Assessors should be trained together and their scores compared for consistency. Kestrel should track pass rates by group at each stage, as the employment law analysis in Unit 2 recommended, and compare new hires' first-year project results with their selection scores to check that the system predicts as expected.
Conclusion
Kestrel's current method relies on the predictor research ranks among the weakest, for a role where errors are expensive. A structured interview, a schedule-recovery exercise built from real work and structured reference checks should predict performance about twice as well, with less adverse impact than an ability test and a better experience for scarce candidates. At about $1,450 per finalist, the system's cost is small against a gain likely in the hundreds of thousands of dollars.

Reading the GB 520 Unit 5 instructions
In GB520 Unit 5 you compare selection methods for a role and recommend a system. Describe the role and why selection errors are costly. Compare several predictors on published validity, adverse impact, cost and likely candidate reactions, citing research for each. Consider the organization's constraints, such as the size of the applicant pool and legal exposure. Recommend a system, explaining why each predictor is included or dropped. Then estimate the system's value with a utility model, stating every input, and test a conservative version. Close with risks and how the system will be monitored. Cite selection research in APA 7.
How this GB520 Unit 5 example is built
The analysis describes the project manager role, multimillion-dollar installations and Kestrel's mixed record with its current method. Table 1 compares five predictors, citing Schmidt and Hunter and the revised estimates of Sackett and colleagues, and the highlighted sentence notes Kestrel's reliance on the weakest. Table 2 weighs the small applicant pool, legal exposure, candidate experience and cost. The recommended system uses a structured interview, the schedule-recovery exercise and structured references, dropping the ability test and personality inventory. The utility estimate, following Cascio and colleagues, uses bracketed inputs for hires, tenure, validity, SDy and selection ratio. Monitoring covers exercise security, assessor consistency and pass rates by group. The conclusion notes that the system should predict about twice as well as the current method at about $1,450 per finalist.
GB520 Unit 5 rubric: what earns full points
GB520 instructors look for predictors compared on several criteria with accurate research and a recommendation that explains every choice. Validity estimates should be cited correctly, including revisions to older figures. Adverse impact, cost and candidate reactions should carry weight alongside validity. Explaining why some predictors are dropped shows judgment. A work sample built from the real job earns credit. The utility estimate carries significant weight when every input is stated and a conservative version is tested. Monitoring by group completes it. Schmidt and Hunter, Sackett's revised validity estimates and Cascio on utility analysis form the analysis's APA 7 list.
GB520 Unit 5 help: mistakes that cost points
Many GB520 Unit 5 analyses rank predictors by validity alone and recommend the top two. Others cite older validity figures without noting recent revisions. A common gap is the utility estimate: a single large figure without stated inputs or a conservative case invites doubt. Some writers ignore candidate reactions, which matter when experienced candidates can walk away. Compare predictors on several criteria, fit them to the organization's constraints, explain each inclusion and exclusion, state every utility input, test a conservative version and plan monitoring. Rotating versions of a work exercise and checking assessors' agreement are details graders often look for. Graders also reward a short statement of what the utility figure cannot capture, such as offers declined or the cost of a bad hire's departure, because it shows the estimate is understood rather than only computed.

GB520 Unit 5 questions, answered
What is a utility analysis?
A way of estimating the dollar value of using a better selection method. The Brogden-Cronbach-Gleser model multiplies the number hired, their expected tenure, the method's validity, the dollar value of performance differences and the average standing of those selected, then subtracts testing costs. The example works it through with bracketed figures and identifies which input deserves the most skepticism.
Why not use a cognitive ability test if it predicts well?
It does predict performance, but it also shows larger average group differences than most methods, which raises adverse impact risk. Recent research suggests its validity is lower than older estimates, and a scored interview combined with a work exercise captures much of the same information. The example argues the incremental value does not justify the exposure for this role.
Does the analysis need statistics?
Some. The example reports published validity estimates and works a utility formula, but it explains each in plain language. Graduate sections generally want quantitative reasoning shown, not advanced statistics. If your course has covered a specific model, the analysis can use that model's terms instead, and the tables keep the same layout.
