Unit 3 Five Forces Industry Analysis

Tollefson Body Works and its figures are composite and illustrative; the industry structure described and the sources cited are real.
Defining the Industry
The industry analyzed here is the building of insulated and refrigerated bodies for straight trucks sold in the United States and Canada. It excludes refrigerated trailers, which are built by a different and more concentrated set of manufacturers, and refrigerated cargo vans, which are converted from factory vans. Both appear below as substitutes. Porter (2008) warns that defining an industry too broadly or too narrowly distorts every rating, and this definition follows the way fleets actually buy: a straight-truck body is quoted, specified and purchased separately from trailers and vans.
The industry is fragmented. A few national builders run several plants each, and dozens of regional builders and small upfitters serve local fleets. A typical refrigerated straight truck in the Class 4 to 6 range might cost a fleet about $140,000 to $180,000 with a diesel chassis, of which the insulated body accounts for perhaps $30,000 to $40,000 and the refrigeration unit for a similar amount. The rest is the chassis.
Supplier Power: High, Steady
Two suppliers matter most. Refrigeration units for trucks come overwhelmingly from two companies, Carrier Transicold and Thermo King, which together supply the large majority of units sold in North America. A body builder cannot sell a refrigerated truck without one of their units, and the unit makers set prices and lead times with little pressure from any single builder.
Chassis are the second supplier, though often an indirect one. Customers or dealers usually buy the chassis, but body builders depend on truck makers' allocation programs to receive chassis in time to build. When chassis are scarce, as they were after 2021, builders wait, and their plants run below capacity. Supplier power is therefore rated high and is not weakening, since neither the refrigeration market nor the chassis market is becoming less concentrated.
Buyer Power: Moderate to High, Strengthening
The largest buyers are truck leasing companies and big grocery and foodservice fleets, which order bodies by the hundred and can ask several builders to quote the same specification. A regional fleet ordering a dozen bodies a year has less bargaining power, but it can still compare quotes. Switching costs for buyers are low, because bodies are built to industry dimensions and can be specified from any competent builder. Buyer power is rated moderate to high and is strengthening as leasing companies, which buy on price, take a larger share of the fleet market.
Rivalry: High, Steady
Rivals compete mainly on price and delivery time, with national builders able to price close to their costs on large orders because their plants spread overhead across high volume. Regional builders compete on responsiveness and custom engineering. Industry capacity is adequate to meet demand in most years, and demand rises and falls with fleet replacement cycles, which keeps price competition intense in slow years. Rivalry is rated high.
In this industry, the companies that decide what a refrigerated truck costs are mostly the ones that do not build its body.
Threat of Entry: Moderate, Steady
Entry is rated moderate rather than low. A small upfitter can start building dry freight bodies with modest capital, but refrigerated bodies require foam injection or panel lamination equipment, thermal testing and certification for food transport, which raises the cost of entry. More important, new entrants struggle to win fleet accounts, which depend on a record of bodies that hold temperature for years. Dealer relationships are another barrier, since dealers prefer builders who deliver reliably.
Threat of Substitutes: Moderate, Strengthening
Two substitutes compete for the same deliveries. Refrigerated cargo vans, converted from factory vans with insulation kits, are cheaper and easier to drive, and they have taken a share of urban grocery and pharmacy deliveries. Refrigerated trailers serve longer routes and higher volumes. As urban delivery grows, vans gain, so the threat of substitutes is rated moderate and strengthening.
Summary of the Five Forces
Ranked by strength, supplier power and rivalry are highest, buyer power is moderate to high and rising, and entry and substitutes are moderate. Taken together, the forces explain why body builders earn thin margins: they buy from concentrated suppliers, sell to concentrated buyers and compete with many similar firms. Grant (1991) argues that in industries where structure offers little profit, sustained returns depend on what individual firms can do better than rivals, which is the subject of Unit 4.
What the Structure Means for Tollefson
For a regional builder of Tollefson's size, the forces translate into three practical facts. It cannot win on price against national builders on large leasing orders, because those rivals spread overhead across several plants. It cannot negotiate better terms from the refrigeration unit makers, which sell to every builder on similar conditions. And its fleet customers can move to another builder at the next order with little cost. What the forces leave open is the space where a buyer's requirement is unusual enough that few builders can meet it. Today that space is custom engineering for dairy and multi-temperature grocery routes, where Tollefson has built its reputation. The question for the rest of the term is whether a lighter body for electric chassis would be a larger version of that same space, a requirement strict enough that fleets cannot simply take the lowest quote.
The Force That Could Turn
The term question asks whether Tollefson should build lightweight bodies for electric chassis. Electric trucks would change one force more than the others. Supplier power from chassis makers could ease. Several new electric truck makers, some without established body builder networks, need partners who can engineer bodies light enough to offset battery weight and integrate with electric refrigeration units. A builder that can do that becomes a partner the chassis maker needs, rather than one more customer in the allocation queue. Brandenburger and Nalebuff (1996) describe firms whose products make each other more valuable as complementors, and in the electric segment, lightweight body builders and chassis makers would be exactly that.
The other forces would move less. Refrigeration unit makers would keep their position, since they already sell electric units. Buyers would still compare quotes, though fewer builders might be able to meet a strict weight target. The analysis therefore finds one structural opening, in the relationship with chassis makers, and it is the opening a lightweight strategy would target.

The Purdue Global GB580 Unit 3 instructions
The third GB580 paper asks you to apply Porter's five forces to your company's industry. Begin by defining the industry precisely, including what you exclude and why; trailers, vans or adjacent products often belong among substitutes rather than rivals. For each force, give a rating, the evidence behind it and whether the force is strengthening or weakening. Rate the industry, not your company; the firm appears when you discuss implications. Summarize the forces in a ranking and explain what the structure means for industry profits. Then return to the term question and ask how it would change each rating. Some sections accept complementors as a sixth consideration. Expect about seven pages, with at least one piece of evidence per force and APA 7 references.
Inside the GB580 Unit 3 example
The analysis begins by defining its industry and pricing a typical truck, about $140,000 to $180,000 of which the body takes $30,000 to $40,000, with Porter's warning about definition cited. One section per force follows. Suppliers rate high because of Carrier Transicold, Thermo King and chassis allocation queues; buyers rate moderate to high as leasing companies grow; rivalry rates high on price and delivery; entry and substitutes rate moderate. The highlighted sentence notes who really sets the truck's price. A ranking and Grant's resource-based argument lead into a section on what the structure means for Tollefson, and the final section uses Brandenburger and Nalebuff's complementors to show how electric chassis could change supplier power.
Where the points sit in the GB580 Unit 3 rubric
Points in a GB580 five forces paper rest heavily on the industry definition, because every rating depends on it. A precise boundary with stated exclusions earns credit that a vague industry label cannot. Each force needs a rating, specific evidence and a direction of change; ratings without evidence earn little. Rating the industry rather than the company shows understanding of what the framework measures. A summary ranking that explains why profits are high or low connects the forces to economics. The strongest papers then ask how the term question would move each rating, which turns a standard framework into input for the decision. Clear headings, accurate industry facts and APA 7 citations finish the rubric.
GB580 Unit 3 help from the desk
The most common GB580 five forces error is rating the forces from the company's point of view, which confuses industry structure with one firm's position. Another is defining the industry so broadly that rivals, substitutes and suppliers blur together. Many papers rate each force without any evidence, or with evidence about the economy in general rather than the industry. Directions of change are often left out, so the paper describes a snapshot when the course asks about strategy. Some writers list the forces and stop, never saying what the structure means for profits or for the firm. Define the industry tightly, back every rating with a fact, show whether each force is strengthening and finish by testing the term question against the ratings.

GB580 Unit 3 questions, answered
Should the five forces paper cover the whole industry or just the company?
The industry. The framework describes the structure every firm in a market faces, so the ratings belong to the industry, and the company appears in the implications section. Papers that rate forces from one firm's point of view tend to confuse strategy with structure. Defining the industry narrowly, by product and geography, keeps that distinction clean and the evidence manageable.
Where do complementors fit?
Some sections accept a sixth force for complementors, the producers whose goods make yours more valuable. For truck bodies, chassis makers and refrigeration unit makers are both suppliers and complementors, which is worth a paragraph of its own. If your rubric lists only five forces, a short note on complementors inside the supplier section usually does no harm.
How much data does a rating need?
One solid piece of evidence per force is a reasonable floor, such as a concentration figure, a trade association statistic or a documented lead time. Private industries rarely publish neat numbers, so a paper can reason from what is observable, like how many builders a fleet can realistically quote. Stating the basis of each rating matters more than precision.

Why are refrigerated vans treated as substitutes rather than rivals?
Because they meet the same need, cold delivery, with a different product built by different firms. Fleets choosing between a van and a straight truck are substituting, not comparing two body builders.
