Short-Term Service Capacity Options

Short-term capacity planning involves adjustments made over a time horizon of less than one month to match capacity with fluctuating demand. In service organizations, where inventory cannot be used to buffer demand swings, short-term options are critical. These include personnel adjustments (overtime, part-timers, transfers), subcontracting, sharing capacity with other organizations, and leasing equipment or space. These tools allow managers to respond quickly to demand variations without making permanent capacity changes.

Imagine you run a small bakery. Most days, your two bakers can handle all the orders. But sometimes you get a huge catering order for 500 cookies tomorrow, or a regular baker calls in sick. You have several quick options: (1) Ask your bakers to stay late (overtime), (2) Call a part-time baker you know (part-timer), (3) Borrow a baker from your friend’s bakery (sharing capacity), (4) Rent an extra mixer for the day (leasing equipment), or (5) Pay another bakery to make some cookies for you (subcontracting). These are all short-term fixes—you’re not building a new bakery or hiring forever, just adjusting for today’s special situation.


Short-Range Capacity Planning: Capacity adjustments made over a time horizon of less than one month [MGH_book.pdf]. These are tactical, reversible decisions that do not require major capital investment.

In service settings, short-term capacity options are especially important because:

  • Services cannot be inventoried (you can’t store today’s unused capacity for tomorrow)
  • Demand often fluctuates unpredictably
  • Customer contact means capacity adjustments must be visible and immediate

Key Personnel Options:

  • Overtime: Existing workers work beyond scheduled hours
  • Undertime: Workers work fewer hours during slow periods
  • Part-timers: Temporary or seasonal workers for peak periods
  • Transfers: Moving employees from one department/task to another based on demand [Chapter5.pptx, Slides 23-24]

Key Capacity Options:

  • Subcontracting/Outsourcing: Paying external providers to handle overflow work [Chapter5.pptx, Slide 23]
  • Sharing Capacity: Multiple organizations share resources during peaks
  • Leasing: Renting equipment or space temporarily rather than purchasing [MGH_book.pdf]

Option TypeSpecific OptionsBest Used When
Personnel AdjustmentsOvertime, undertime, part-timers, transfers [Chapter5.pptx, Slides 23-24]Demand fluctuations are predictable or short-duration
SubcontractingOutsourcing work to external providers [Chapter5.pptx, Slide 23]Internal capacity is insufficient; external providers have available capacity
Capacity SharingExchanging capacity with other organizations (e.g., airlines exchanging aircraft) [MGH_book.pdf]Multiple organizations face complementary demand patterns
LeasingRenting equipment or space temporarily (e.g., E-Education leasing office space) [MGH_book.pdf]Need is temporary; purchase is not justified
OptionAdvantageDisadvantage
OvertimeNo hiring/training needed; workers already skilledPremium pay (1.5x wages); worker fatigue
UndertimeRetains skilled workers during slow periodsWorkers may leave for steady employment; underutilized labor cost
Part-timersFlexible scheduling; lower benefit costsLess commitment; more training needed
TransfersUtilizes existing workforce flexiblyRequires cross-training; may disrupt original department

Subcontracting vs. In-House Decision Factors

Capacity Sharing Example (Airlines): Major airlines sometimes exchange aircraft during peak travel periods. If Airline A has high demand on a route but insufficient aircraft, it can lease capacity from Airline B. This allows both airlines to serve customers without permanently expanding their fleets [MGH_book.pdf].

Leasing Example (E-Education Startup): An online education startup experienced rapid growth and needed additional office space immediately. Instead of signing a long-term lease or buying property, the company leased additional office space on a short-term basis. This provided flexibility—the company could expand or contract space as growth continued without being locked into a fixed commitment [MGH_book.pdf, Chapter 19].

Personnel Adjustment Example (Restaurant): A restaurant faces high demand on Friday and Saturday nights but slower weekday business. The manager uses:

  • Part-timers: College students working only weekend evenings
  • Overtime: Cooks staying an extra hour during unexpected rushes
  • Transfers: Host helping with takeout orders during dinner rush

Subcontracting Example (Manufacturing): A furniture manufacturer receives an order larger than its current capacity can handle. Instead of turning down the order or delaying delivery, the company subcontracted the finishing work to a nearby shop. This allowed the order to be completed on time without permanent capacity expansion [Chapter5.pptx].


Why short-term service capacity options matter:

  1. Flexibility Without Commitment: Short-term options allow organizations to respond to demand without making irreversible long-term investments. Leasing, part-timers, and subcontracting can all be scaled up or down quickly [MGH_book.pdf].

  2. Cost Management: Using overtime and part-timers is often cheaper than maintaining a large permanent workforce. Organizations pay for capacity only when they use it [Chapter5.pptx].

  3. Service Quality: In services, capacity shortages directly impact customer experience (long waits, turned-away customers). Short-term options provide buffers to maintain service levels [MGH_book.pdf].

  4. Risk Mitigation: Capacity sharing and subcontracting spread risk across multiple organizations. If one provider has problems, others can fill gaps [MGH_book.pdf].

  5. Strategic Agility: Organizations with diverse short-term options can pursue opportunities (large orders, seasonal peaks) that would be impossible with fixed capacity alone [MGH_book.pdf].


ConceptRelationship to Short-Term Service Options
Aggregate PlanningShort-term options are tactical tools within aggregate planning framework
Chase StrategyShort-term personnel adjustments support chase strategy implementation
Service CapacityServices rely more heavily on short-term options since inventory is not available
Capacity UtilizationShort-term options help maintain optimal utilization during demand fluctuations
OutsourcingSubcontracting is a form of outsourcing for capacity supplementation

For Exam Recall:

  • Time Horizon: Short-range = less than one month [MGH_book.pdf]
  • Personnel Options: Overtime, undertime, part-timers, transfers [Chapter5.pptx, Slides 23-24]
  • Subcontracting: Outsourcing work to external providers [Chapter5.pptx, Slide 23]
  • Capacity Sharing: Airlines exchanging aircraft example [MGH_book.pdf]
  • Leasing: E-Education startup leasing additional office space example [MGH_book.pdf]

Exam Tips:

  • Short-term = reversible, tactical decisions (not permanent capacity changes)
  • Services CANNOT use inventory, so short-term options are CRITICAL
  • Remember the airline and E-Education examples—exam may ask for specific applications
