One newcomer climbed up from homeowner machines and one won on quality at the top; this MT451 Unit 5 analysis calls only the first disruptive, applying Christensen strictly. Searches like "mt 451 unit 5 assignment example", "mt451 unit 5 sample" and "mt451 unit 5 example" land here.
What a finished MT451 Unit 5 disruption case analysis looks like
Seven pages with a definition box, two trajectory charts and a verdict table. The box states Christensen's definition as restated in his 2015 Harvard Business Review article with Raynor and McDonald: a smaller entrant starts where incumbents are not looking, among their least demanding customers or among people not buying at all, offers something inferior on what the core market prizes, and climbs until that market defects. The first chart tracks the tool brand from a 21-inch homeowner mower around 2015 to a 52-inch zero-turn at $11,900 in 2024, against $16,500 for comparable gas machines, with runtime rising from under an acre to about five. The second tracks the premium rival's commercial share, 9 percent in 2021 to 15 in 2025, at $19,800 a unit. The verdict table scores each newcomer on four tests.
How a MT451 Unit 5 example is structured
The definition comes first and is applied as a set of tests rather than a label: where the entrant started, how its product compared on mainstream measures at entry, whether incumbents had reason to ignore it, and whether it has since moved upmarket. Each newcomer runs through all four in the same order, which lets the verdict table show where the premium rival fails, at the first test, since it entered at the top of the market through incumbents' dealers. Christensen's mini-mill example supplies the reference pattern. The 2015 article's argument that Uber was not disruptive is cited as a caution against applying the label to every successful entrant. Last comes the incumbent: the tool brand's thin margins make it unattractive to chase, and that very logic, the paper argues, is why a separate unit may be needed.
The definition as four tests
Starting position, product quality on mainstream measures at entry, incumbents' reason to ignore the entrant, and movement upmarket since. Each newcomer faces all four, in order.
From push mower to zero-turn
The tool brand began with 21-inch homeowner machines around 2015, a segment commercial makers did not serve, and reached a 52-inch commercial zero-turn in 2024 at $11,900.
Worse at entry, better each year
Runtime climbed from under an acre per charge to about five. Among small crews running one to three mowers, the brand's share rose from 0.5 percent in 2023 to 4 percent in 2025.
A rival that simply cut better
The premium stand-on mower entered at $19,800 through incumbents' own dealers and won share on cut quality and comfort. Sustaining innovation is the paper's verdict: successful, but not disruptive.
Why chasing it looks unattractive
Margins on an $11,900 machine sit far below those on gas lines, so the incumbent has good reason to ignore it. The paper calls that reasoning the danger and proposes a separate unit.
Where marks go in MT451 Unit 5
Disruption papers in MT451 are graded heavily on precision, and calling any successful newcomer disruptive is the error instructors mark most often. A paper labeling the premium rival disruptive because it took share has described competition, not disruption. Graders usually expect the definition stated, sourced and applied test by test. Evidence of the entrant's starting position is essential, and papers asserting a low-end foothold without dates or prices leave it unproven. Incumbent motivation deserves space, since the theory turns on why established firms rationally ignore an entrant; blaming incumbents for laziness misses the mechanism. Treating disruption as a verdict on success rather than a description of path is a related confusion. Recommendations telling the incumbent to match the entrant's product inside its existing business seldom engage with the theory's own advice.

MT451 Unit 5 questions, answered
Is every newcomer that beats incumbents a disruptor?
No. In Christensen's sense, disruption describes a path: a foothold among the least demanding customers or among non-consumers, an offering that begins behind on the attributes the core market cares about, and steady improvement until that market moves across. A newcomer that wins with a better product aimed at the incumbents' best customers is a sustaining innovator, however successful it becomes.
Which source should I cite for the definition?
Christensen's own work is the standard reference: The Innovator's Dilemma for the original theory, and the 2015 Harvard Business Review article with Raynor and McDonald, which restated the definition and discussed common misuses. Check whether your course text frames it differently, and cite the version you apply so the grader can hold your analysis to it.
What should the incumbent do if the entrant is disruptive?
Christensen's work generally suggests that responding inside the existing business fails, because its cost structure and customers pull resources toward the high end. A separate unit with its own cost structure and profit expectations is the usual recommendation. Your analysis should weigh that against the firm's circumstances rather than treating it as automatic.
