S Curve Adoption Phase Innovators Laggards Mapper
Map cumulative adoption to an adopter phase using five caller-supplied, nondecreasing category cutoffs.
Description
Adopter phase labels describe where cumulative adoption lies against category endpoints.
Adopter phase labels describe where cumulative adoption lies against category endpoints. This tool uses caller-provided cutoffs.1
The returned values include Adopter category, Category index, Next cutoff percent. The How section below explains the calculation, input rules and interpretation.
When to use S Curve Adoption Phase Innovators Laggards Mapper
Use S Curve Adoption Phase Innovators Laggards Mapper when you need to evaluate the supplied records under the calculation and evidence rules below. No curve fitting or default empirical diffusion distribution is provided.
Define the question, evidence and scenario assumptions first. Supply the chosen score scales, time horizons or reference selection explicitly. Interpret generated text as a discussion template and screen labels as the stated rules.
How to use S Curve Adoption Phase Innovators Laggards Mapper and understand its results
- Define the question, evidence and scenario assumptions first. Supply the chosen score scales, time horizons or reference selection explicitly. Interpret generated text as a discussion template and screen labels as the stated rules.
- Enter categoryCutoffsPercent, cumulativeAdoptionPercent using the field table and calculation rules, then run the tool.
- Read category, categoryIndex, nextCutoffPercent. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| categoryCutoffsPercent | Exactly five upper cumulative-adoption cutoffs ending at 100. (%) | list of number | Required |
| cumulativeAdoptionPercent | Cumulative adoption percent (%) | number; minimum: 0; maximum: 100 | Required |
Require adoption 0–100 and exactly five finite nondecreasing cutoffs 0–100 with final 100. Select first inclusive cutoff and return category, zero-based index and that cutoff. Equal cutoffs can make categories unreachable.
index=first cutoff≥adoption Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| category | Adopter category | string; one of "innovators", "earlyAdopters", "earlyMajority", "lateMajority", "laggards" |
| categoryIndex | Category index | integer; minimum: 0; maximum: 4 |
| nextCutoffPercent | Next cutoff percent (%) | number; minimum: 0; maximum: 100 |

}Limitations and assumptions
No curve fitting or default empirical diffusion distribution is provided.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Core numeric and string lists are limited to 100,000 entries; text entries are subject to the general large-text limit. Follow any smaller calculation limits above. Missing fields without a declared default, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Rogers Diffusion Adopter Categories Percent Split: Cumulative adopter cutoffs must be differenced to obtain category shares. Their meaning differs from five shares that already sum to 100. For a complementary task, use Crossing the Chasm Early Majority Gap Strategy Lookup: An early-majority adoption barrier may concern affordability, compatibility, credibility, usability or value. This reference links a chosen barrier to a generic strategy and evidence target.
