Why it matters

Standard times are only half the story: the plant also has to decide what each job is worth and how to reward workers who beat the standard. Job evaluation sets fair base pay between jobs, and a wage incentive plan links extra pay to performance. A badly designed plan causes quality problems, disputes and loose standards, so engineers who set standards must understand how the money is calculated.

Key ideas

Job evaluation vs merit rating. Job evaluation rates the job, not the person: it ranks jobs by their demands so that base wages are internally fair. Merit (performance) rating rates the person doing the job. Incentives reward output above the standard.

Job evaluation methods

  • Non-quantitative: ranking (whole jobs placed in order of overall worth; simple, suits small firms, but gives no measure of how far apart jobs are); grading or classification (jobs slotted into predefined grades with written descriptions, as in government pay scales).
  • Quantitative: point method (choose compensable factors such as skill, effort, responsibility and working conditions, split each into degrees, give each degree points; a job's total points place it on a wage line drawn through benchmark jobs); factor comparison (key jobs' wages are split among factors and other jobs are compared factor by factor in money terms).

Requirements of a sound incentive plan: based on accurate standards from work study; simple for workers to calculate; a guaranteed minimum (time) wage; payment soon after the work; no ceiling on earnings; quality checked so that only good output counts; agreed with the workers and not cut once workers earn more.

Individual plans

  • Time rate (day work): pay = hours × rate; no direct incentive, used where output cannot be measured or quality is critical.
  • Straight piece rate: pay = pieces × rate per piece, usually with a guaranteed minimum.
  • Taylor's differential piece rate: a low piece rate below standard output and a higher one at or above it; strong incentive, harsh on learners.
  • Merrick's multiple piece rate: three rates (below about 83 %, 83–100 %, above 100 % of standard), softer than Taylor.
  • Gantt task and bonus: guaranteed time wage below standard; at standard, a bonus of about 20–35 % on the standard time.
  • Halsey premium plan: time wage plus a fixed share (usually 50 %, sometimes 33⅓ %) of the time saved, paid at the hourly rate. The firm keeps the other share.
  • Rowan plan: time wage plus a bonus whose percentage of the time wage equals the percentage of time saved. Bonus is largest when the job takes half the standard time and then falls, which protects against loose standards.
  • Standard hour (100 % premium) plan: paid the standard time for the job regardless of the time taken (with guaranteed time wage). Equivalent to a piece rate expressed in time.
  • Emerson efficiency plan: a bonus starting at about 67 % efficiency and rising with efficiency; Bedaux point plan: work measured in "B" units (1 B = 1 standard minute), 75 % of the time saved paid to the worker.

Group and plant-wide plans: group bonus (team output), Scanlon plan (labour-cost savings shared, with suggestion committees), Rucker plan (based on value added), Improshare (hours saved against a standard), and profit sharing. They encourage teamwork but weaken the individual link between effort and pay.

Formulas

Let S = standard (allowed) time (h), T = actual time taken (h), R = hourly rate (₹/h).

Time wage = T × R

Halsey: Earnings = T·R + p·(S − T)·R, with p = 0.5 (or 1/3)

Rowan: Earnings = T·R + [(S − T)/S]·T·R

Standard hour: Earnings = S·R (if T < S; otherwise T·R)

Rowan bonus is maximum at T = S/2, where bonus = S·R/4 and total earnings = 0.75·S·R

Effective hourly rate = Earnings / T

Point-method wage line: W = W₁ + (W₂ − W₁)(P − P₁)/(P₂ − P₁)

  • P = job points; (P₁, W₁) and (P₂, W₂) = two benchmark jobs.

Worked examples

Example 1 (standard). Standard time for a job is 10 h; a worker finishes it in 8 h; the time rate is ₹150/h. Find the earnings and effective hourly rate under the Halsey 50 % plan, the Rowan plan and the standard hour plan.

  1. Time wage: 8 × 150 = ₹1,200; time saved = 2 h.
  2. Halsey: 1,200 + 0.5 × 2 × 150 = ₹1,350 (₹168.75/h).
  3. Rowan: 1,200 + (2/10) × 8 × 150 = 1,200 + 240 = ₹1,440 (₹180/h).
  4. Standard hour: 10 × 150 = ₹1,500 (₹187.50/h).

Example 2 (GATE level). Standard time 12 h, rate ₹160/h. (a) At what time T does the Rowan bonus peak, and what is it? (b) Compare Rowan and Halsey 50 % bonuses at T = 6 h and T = 9 h. (c) A point-rated job of 380 points lies on a wage line through benchmark jobs of 200 points (₹18,000/month) and 500 points (₹30,000/month); find its wage.

  1. (a) Rowan bonus B = T(S − T)R/S; dB/dT = 0 gives T = S/2 = 6 h; B = 6 × 6 × 160 / 12 = ₹480, total ₹1,440, i.e. ₹240/h.
  2. (b) At T = 6 h: Halsey bonus 0.5 × 6 × 160 = ₹480, the same as Rowan. At T = 9 h: Rowan 9 × 3 × 160 / 12 = ₹360; Halsey 0.5 × 3 × 160 = ₹240. Rowan pays more for modest savings (T > S/2) and less for very large ones (T < S/2).
  3. (c) Slope = (30,000 − 18,000)/(500 − 200) = ₹40 per point; W = 18,000 + 40 × (380 − 200) = ₹25,200 per month.

Common mistakes

  • In Rowan, using (S − T)/T instead of (S − T)/S, or forgetting to multiply by the time wage T·R.
  • In Halsey, paying the share of time saved at a piece rate instead of the hourly rate.
  • Forgetting the guaranteed time wage when T > S (no plan pays less than time wage).
  • Mixing up job evaluation (rates the job) and merit rating (rates the worker).
  • Treating ranking or grading as quantitative methods; only the point and factor-comparison methods use numbers.

For GATE PI

Expect NAT questions on earnings or effective hourly rate under Halsey, Rowan, standard hour and differential piece rate plans, the Rowan maximum, and one-mark questions on job evaluation methods and the features of a good incentive plan. Practise writing S, T and R clearly before substituting.

Quick check

  1. S = 8 h, T = 6 h, R = ₹100/h. Halsey 50 % earnings?
  2. Same data, Rowan earnings?
  3. At what fraction of standard time is the Rowan bonus largest?
  4. Which job evaluation method uses degrees and points for each factor?

Answers: 1. 600 + 0.5 × 2 × 100 = ₹700; 2. 600 + (2/8) × 600 = ₹750; 3. Half the standard time; 4. The point method.

  1. 1.What is a wage incentive plan?Concept

    A wage incentive plan is a system designed to motivate employees by linking their compensation to their performance. It typically involves offering bonuses, commissions, or other financial rewards based on the achievement of specific performance targets or productivity levels. The goal is to encourage higher productivity and efficiency among workers.

  2. 2.Explain the concept of job evaluation.Concept

    Job evaluation is a systematic process used to determine the relative worth of jobs within an organization. It involves assessing various factors such as skills, responsibilities, effort, and working conditions to establish a job hierarchy. This helps in setting fair and equitable wage structures and ensuring that employees are compensated appropriately for their roles.

  3. 3.Why are wage incentive plans used in manufacturing industries?Application

    Wage incentive plans are used in manufacturing industries to boost productivity and efficiency. By tying compensation to performance, these plans encourage workers to produce more output in less time, reduce waste, and improve quality. This can lead to lower production costs and higher profitability for the company.

  4. 4.What happens if a wage incentive plan is poorly designed?Application

    If a wage incentive plan is poorly designed, it can lead to unintended consequences such as decreased morale, increased stress, and unhealthy competition among employees. It may also result in a focus on quantity over quality, leading to defects and rework. Ultimately, it can harm productivity and employee satisfaction.

  5. 5.How does job evaluation contribute to fair wage determination?Application

    Job evaluation contributes to fair wage determination by providing a structured approach to assess the value of different jobs within an organization. By evaluating factors like skills, responsibilities, and working conditions, it ensures that employees are compensated based on the demands of their roles. This helps in maintaining internal equity and reducing wage disparities.

  6. 6.What are the common methods used in job evaluation?Concept

    Common methods used in job evaluation include the ranking method, classification method, point factor method, and factor comparison method. Each method has its own approach to assessing job value, such as ranking jobs in order of importance, classifying them into predefined categories, or assigning points based on specific job factors.

  7. 7.Explain the point factor method of job evaluation.Concept

    The point factor method of job evaluation involves breaking down a job into key factors such as skills, responsibilities, and working conditions. Each factor is assigned a weight or point value based on its importance. The total points for a job determine its relative worth within the organization, helping to establish a fair wage structure.

  8. 8.What are the potential challenges in implementing a job evaluation system?Application

    Challenges in implementing a job evaluation system include ensuring objectivity, managing employee perceptions, and maintaining consistency across evaluations. It can be time-consuming and may require regular updates to reflect changes in job roles. Additionally, there may be resistance from employees who feel their jobs are undervalued.

  9. 9.Compare the Halsey and Rowan premium plans.Concept

    Both guarantee the time wage and add a bonus for time saved against the standard time S. Halsey pays a fixed share, usually 50 %, of the time saved at the hourly rate, so the bonus keeps rising as the worker gets faster. Rowan pays a bonus equal to (time saved / standard time) × time wage; it rises to a maximum when the job takes half the standard time and then falls. So Rowan is more generous for modest savings, but protects the employer against loose standards and discourages rushing that hurts quality.
