14.2 Capital Equipment and Facilities

Domain IX pairs quality with technology and investment decisions because better processes frequently need better assets. A poka-yoke fixture is a small capital item; a new CNC cell, automated storage, or greenfield plant is a large one. CPIM expects planners to understand how capital equipment and facilities reshape capacity, lead times, and inventory—and how managers roughly judge whether those investments are worth making.

Capacity Strategy: Lead, Lag, and Match

Before you approve a machine purchase, you need a capacity strategy—a policy for how capacity will track demand over time.

Exam scenarios often hide the strategy in the story. A firm that “will not hire or buy equipment until backlog exceeds eight weeks” is lagging. A firm that builds a plant sized for year-five volume while year-one demand is half that size is leading. Planners must translate the strategy into master scheduling aggressiveness, subcontracting plans, and inventory builds.

Capacity strategy is not the same as a one-time capacity calculation. Rough-cut capacity planning (RCCP) and capacity requirements planning (CRP) measure load versus available hours given today’s assets. Capital strategy decides when “today’s assets” will change.

Make-or-Buy Capacity Decisions

Make-or-buy for capacity asks: should incremental demand be absorbed with internal equipment/labor, or purchased from a contract manufacturer, toll processor, or logistics partner?

Factors CPIM-style questions emphasize:

• Variable and fixed cost — internal production may have higher fixed cost but lower variable cost at volume
• Control and quality — proprietary processes, IP, or tight tolerances may force “make”
• Lead time and flexibility — external capacity can ramp faster if suppliers have slack; it can also vanish in industry-wide shortages
• Core competence — keep differentiating processes in-house; buy commodities
• Risk and dual sourcing — even “make” firms often retain some external capacity for surge and disaster recovery

A classic trap is comparing only the supplier’s piece price to the internal variable cost while ignoring the capital you would otherwise spend—or conversely, ignoring the capital you already own (sunk cost) when deciding whether to fill idle hours. For planning purposes: sunk costs do not change the forward decision, but opportunity cost of scarce bottleneck hours does.

Example: painting is a bottleneck. You can buy a second paint line for $1.2M or subcontract overflow at $18/unit. If subcontracting covers a temporary surge and painting is not strategic IP, buy capacity may wait. If every product must be painted in-house for corrosion warranty reasons, make capacity becomes mandatory and the strategy discussion shifts to lead vs. lag timing.

Facility Decisions

Facilities decisions set the physical envelope of the supply chain: where you produce, how large the site is, and how it is organized.

Key decision themes:

1. Location — proximity to customers, suppliers, labor, ports, and regulation; total landed cost matters more than rent alone
2. Size and scalability — oversized plants waste capital; undersized plants force premature expansion or chronic overtime
3. Focus — product-focused plants (one family end-to-end) vs. process-focused plants (technology centers feeding many products)
4. Layout implications — product layouts favor flow and short lead times for high volume; process layouts favor flexibility for high mix; cells sit between
5. Centralization vs. decentralization — one large DC vs. regional DCs changes inventory pooling, transportation cost, and service time

Facility choices are hard to reverse. A planner who inherits a process-layout job shop should not invent lead-time promises that only a product-flow line could hit. Conversely, after a capital project converts a department to cellular flow, MRP lead times, lot sizes, and queue allowances should be updated—or the system will keep planning the old world.

Capital Budgeting Awareness for Operations (Not CPA Depth)

Operations leaders are asked to justify projects with simple financial screens. CPIM expects awareness, not discounted-cash-flow wizardry.

Payback period answers: how long until the investment’s cumulative net cash benefits equal the initial outlay?

Payback (years) ≈ Initial investment ÷ Annual net cash inflow

Example: a $600,000 packaging line saves $200,000 per year in labor and scrap. Simple payback is about 3 years. Many firms set a maximum acceptable payback (for example, 2–4 years) as a hurdle. Payback ignores cash flows after the cutoff and the time value of money—so it is a screening tool, not a complete valuation.

Return on investment (ROI) relates benefit to capital:

ROI ≈ Annual net benefit ÷ Investment

Using the same numbers: $200,000 / $600,000 = 33% ROI per year (simple). Firms compare that percentage to a hurdle rate or to competing projects. Again, definitions of “net benefit” vary (pre-tax vs. after-tax, including or excluding depreciation effects). On the exam, focus on the directional logic: higher annual benefit or lower investment improves ROI; longer payback signals slower capital recovery.

What CPIM does not require: full net present value (NPV) schedules, tax shield computations, or weighted-average cost of capital derivations. If a scenario mentions NPV or internal rate of return (IRR), treat them as “time-value-aware” cousins of ROI/payback and reason qualitatively unless numbers are given simply.

Linking Capital Projects Back into Planning Systems

When a capital project goes live, planning data must change:

Failing to update these parameters is a common real-world failure and a fair exam diagnosis: “the new line is live but planners still use the old routing times.”

Quality Connection

Capital is often the enabler of quality strategy: more capable machines raise Cpk; environmental controls reduce special-cause variation; automated inspection increases appraisal speed; flexible cells support smaller lots with less changeover scrap. When you evaluate ROI, include failure-cost reductions—not only direct labor savings—or you will understate the value of quality-driven investments.

Common CPIM Traps

1. Confusing lead/lag capacity strategy with make-to-stock vs. make-to-order fulfillment
2. Treating make-or-buy as price-only comparison
3. Using payback as if it ranked projects perfectly after the payback year
4. Forgetting that facility focus and layout constrain achievable lead times
5. Approving capital without a plan to update MRP/RCCP parameters at cutover
