# Research: "Who Does What By How Much?" -- Outcome-Based Goal Framework

**Date**: 2026-03-06 | **Researcher**: nw-researcher (Nova) | **Confidence**: High | **Sources**: 14

## Executive Summary

"Who Does What By How Much? A Practical Guide to Customer-Centric OKRs" (2024) by Jeff Gothelf and Josh Seiden presents a framework for writing outcome-based goals that measure success through changes in customer behavior rather than through delivery of features or outputs. The book is the culmination of 15+ years of work by the authors across three prior books (Lean UX, Sense & Respond, Outcomes Over Output) and codifies their approach into a three-part formula: **Who** (the customer) **Does What** (specific behavior) **By How Much** (measurable target).

The framework operates on a core insight: business results (revenue, retention, NPS) are lagging indicators that cannot be directly influenced by teams. Instead, teams should target leading indicators -- specific, measurable changes in customer behavior that predict those business results. The book provides a complete operational system including OKR writing templates, check-in cadences, anti-patterns to avoid, and a logic model (Output -> Outcome -> Impact) that maps team work to business KPIs through behavioral intermediaries.

This research synthesizes findings from 14 sources across the authors' direct publications, book summaries, podcast transcripts, and practitioner reviews to extract actionable concepts for integrating outcome-based KPI definition into an AI product owner agent.

## Findings

### Finding 1: The Core Formula -- "Who Does What By How Much"

**Evidence**: The formula structures outcome-based goals into three components: **Who** (the customer or user segment), **Does What** (a specific action or behavior you want to influence), **By How Much** (a quantified, measurable target for that behavioral change).

**Source**: [WiseWords Book Summary](https://wisewords.blog/book-summaries/who-does-what-by-how-much-book-summary/) - Accessed 2026-03-06

**Confidence**: High

**Verification**: [Dan Lebrero Book Notes](https://danlebrero.com/2024/07/09/who-does-what-by-how-much-book-summary/), [CX Wheel Substack Review](https://cxwheel.substack.com/p/16-who-does-what-by-how-much-gothelf-seiden), [Tandi.ch Review](https://www.tandi.ch/blog/who-does-what-by-how-much-a-practical-guide-to-customer-centric-okrs-by-jeff-gothelf-amp-josh-seiden-2024)

**Analysis**: The formula is applied as a litmus test for Key Results within OKRs. If a key result cannot answer "Who does what by how much?", it is likely measuring an output (feature delivery) rather than an outcome (behavior change). The formula enforces customer-centricity by requiring explicit identification of the affected user segment.

**Template**:
```
Key Result = [Who?] [Does what?] [By how much?]

Example: "New users complete their first order within 24 hours 30% more often than last quarter"
- Who: New users
- Does what: Complete their first order within 24 hours
- By how much: 30% more often than last quarter
```

**Additional Examples** (from multiple sources):
- "Returning customers use self-service features to resolve issues without contacting support, reducing tickets by 40%"
- "Application completion rates increase by 90%" (mortgage application context)
- "Increase the percentage of users who complete a purchase from recommendations from 10% to 25%"

---

### Finding 2: Outcome vs. Output -- The Fundamental Distinction

**Evidence**: An outcome is defined as "a measurable change in customer behaviour that creates value." Outputs are "products, policies, content, or tangible items created." The authors emphasize that completing outputs alone does not guarantee value creation -- outcomes must be the focus.

**Source**: [WiseWords Book Summary](https://wisewords.blog/book-summaries/who-does-what-by-how-much-book-summary/) - Accessed 2026-03-06

**Confidence**: High

**Verification**: [Josh Seiden on Intercom](https://www.intercom.com/blog/podcasts/josh-seiden-on-why-product-teams-should-focus-on-outcome-vs-output/), [Produx Labs Podcast](https://www.produxlabs.com/product-thinking-blog/episode-87-josh-seiden), [Airfocus Interview](https://airfocus.com/blog/customer-centricity-okrs-jeff-gothelf/)

**Analysis**: This distinction is the philosophical core of the entire framework. Traditional KPIs and project management track outputs (features shipped, story points completed, velocity). The Gothelf/Seiden framework reframes success entirely: the deployment of code is "just the beginning of the conversation with our customers." A feature has no value until it changes customer behavior in a measurable way.

**Key Implication for AI Product Owner**: When generating requirements, the agent must never define "done" as "feature deployed." Every requirement must include a behavioral outcome that can be measured post-deployment.

---

### Finding 3: The Logic Model -- Output -> Outcome -> Impact

**Evidence**: The book uses a three-tier logic model borrowed from nonprofit program evaluation (originally the W.K. Kellogg Foundation Logic Model): **Outputs** (what teams create) lead to **Outcomes** (measurable behavior changes) which drive **Impact** (long-term business results like revenue, market share, NPS).

**Source**: [Dan Lebrero Book Notes](https://danlebrero.com/2024/07/09/who-does-what-by-how-much-book-summary/) - Accessed 2026-03-06

**Confidence**: High

**Verification**: [Josh Seiden on Intercom](https://www.intercom.com/blog/podcasts/josh-seiden-on-why-product-teams-should-focus-on-outcome-vs-output/), [Produx Labs Podcast with Seiden](https://www.produxlabs.com/product-thinking-blog/episode-87-josh-seiden), [Gothelf Blog on Output/Outcomes/Impact](https://jeffgothelf.com/blog/output-outcomes-impact-and-kpis/)

**Analysis**: The logic model provides the conceptual backbone for outcome mapping. Leadership sets impact-level goals (org-level OKRs). Teams convert these into outcome-focused Key Results. Teams then deliver outputs designed to achieve those outcomes. This creates a traceable chain: Feature -> Behavior Change -> Business Result.

**The three tiers**:

| Tier | Definition | Who Sets It | Example |
|------|-----------|-------------|---------|
| Impact | Long-term business health metrics | Leadership/Executives | Revenue growth, market share, NPS |
| Outcome | Measurable change in customer behavior | Teams (from strategy) | "Users complete purchases from recommendations" |
| Output | Products, features, policies created | Teams (execution) | Recommendation engine, UI redesign |

---

### Finding 4: Leading vs. Lagging Indicators

**Evidence**: Impact metrics are lagging indicators -- they "look backwards to things that have already happened." Outcomes are leading indicators -- "tactical metrics giving a sense of how impact metrics will do in the future." Teams should focus on leading indicators (behavior changes) because they predict and drive lagging indicators (business results).

**Source**: [Gothelf Blog: Output, Outcomes, Impact and KPIs](https://jeffgothelf.com/blog/output-outcomes-impact-and-kpis/) - Accessed 2026-03-06

**Confidence**: High

**Verification**: [Josh Seiden on Produx Labs](https://www.produxlabs.com/product-thinking-blog/episode-87-josh-seiden), [Gothelf Blog: Execs and Revenue](https://jeffgothelf.com/blog/execs-care-about-revenue-how-do-we-get-them-to-care-about-outcomes/), [Easy Agile Podcast](https://www.easyagile.com/podcast/jeff-gothelf-on-customer-centric-okrs-goal-setting-and-leadership-that-scales)

**Analysis**: Seiden illustrates this with a mattress store example: the lagging indicator is "mattress purchases" (hard to influence directly). Leading indicators include "foot traffic" and "customers lying on mattresses" -- behaviors that precede and predict purchases. Teams can run experiments to increase leading-indicator behaviors and observe correlation with the lagging outcome.

**Hierarchy of indicators**:
```
Lagging (Impact):    Revenue, NPS, Market Share
    ^
    | predicts
    |
Leading (Outcomes):  Purchase completion rate, feature adoption, retention behavior
    ^
    | predicts
    |
Leading (Secondary): Page visits, trial starts, onboarding completion
```

Each layer of leading indicator can be decomposed into more granular behavioral metrics, allowing teams to identify the highest-leverage behavior to target.

---

### Finding 5: OKR Structure -- Objectives and Key Results

**Evidence**: **Objectives** are "inspirational, qualitative, timeboxed, and specific" statements describing how the world changes after solving a problem. **Key Results** are quantified behavioral metrics using the "[Who] [Does what] [By how much]" format, with 2-4 key results per objective recommended.

**Source**: [Dan Lebrero Book Notes](https://danlebrero.com/2024/07/09/who-does-what-by-how-much-book-summary/) - Accessed 2026-03-06

**Confidence**: High

**Verification**: [MindTheProduct Interview](https://www.mindtheproduct.com/why-most-companies-struggle-with-okrs-a-conversation-with-jeff-gothelf/), [Airfocus Interview](https://airfocus.com/blog/customer-centricity-okrs-jeff-gothelf/), [CX Wheel Review](https://cxwheel.substack.com/p/16-who-does-what-by-how-much-gothelf-seiden)

**Analysis**: Key distinctions from traditional KPIs and standard OKRs:

| Aspect | Traditional KPIs | Standard OKRs | Customer-Centric OKRs (Gothelf/Seiden) |
|--------|-----------------|---------------|----------------------------------------|
| Focus | Business metrics | Results (often output-based) | Customer behavior change |
| Key Result format | Varies | Often task/output lists | [Who] [Does what] [By how much] |
| Success measure | Hit the number | Achieve 70% of target | Observed behavior change |
| Customer presence | Implicit | Optional | Mandatory (the "Who") |
| Autonomy | Low (prescribed work) | Medium | High (teams choose how) |

**Concrete OKR Example**:
```
Objective: Create the simplest mortgage application for digitally-native
           consumers by end of Q4

Key Results:
1. Application completion rates increase by 90%
   [Who: applicants] [Does what: complete applications] [By how much: +90%]
2. Increase application start rates by 200%
   [Who: visitors] [Does what: start applications] [By how much: +200%]
3. 75% reduction in customer support calls about online mortgage applications
   [Who: applicants] [Does what: resolve issues without support] [By how much: -75% calls]
```

### Finding 6: The Seven Principles of Customer-Centric OKRs

**Evidence**: The book identifies seven foundational principles: (1) Focus -- prioritize fewer strategic goals; (2) Autonomy -- teams determine execution methods; (3) Alignment -- OKRs connect to parent OKRs rather than cascading; (4) Accountability -- transparent progress tracking; (5) Transparency -- universal data access across teams; (6) Agility -- hypothesis-based work, responsive to learning; (7) Customer-centricity -- all goals center on customer value.

**Source**: [Dan Lebrero Book Notes](https://danlebrero.com/2024/07/09/who-does-what-by-how-much-book-summary/) - Accessed 2026-03-06

**Confidence**: High

**Analysis**: The seventh principle (customer-centricity) is the distinguishing innovation. Most OKR frameworks include the first six; Gothelf and Seiden add customer-centricity as non-negotiable. This means every OKR must answer: "What change in customer behavior will indicate that we have been successful?"

---

### Finding 7: The OKR Cycle and Check-In Cadence

**Evidence**: The framework operates as a continuous cycle rather than a linear plan. Check-in cadences include: **Weekly** (30 min, team-only: review KR status, surface blockers, plan actions), **Monthly** (60-90 min with stakeholders: share learnings, discuss obstacles), **Quarterly** (strategic: recommit, update, or discard OKRs), and **Annual** (strategy setting).

**Source**: [Dan Lebrero Book Notes](https://danlebrero.com/2024/07/09/who-does-what-by-how-much-book-summary/) - Accessed 2026-03-06

**Confidence**: High

**Verification**: [WiseWords Book Summary](https://wisewords.blog/book-summaries/who-does-what-by-how-much-book-summary/), [MindTheProduct Interview](https://www.mindtheproduct.com/why-most-companies-struggle-with-okrs-a-conversation-with-jeff-gothelf/)

**Analysis**: The cycle has two layers. **Strategic** (leadership): define strategy, identify strategic key results over 6-12 months. **Team** (execution): five circular activities involving hypothesis generation, discovery, delivery, measurement, and learning. Team OKRs function as "leading indicators to the strategy" while enabling teams to "achieve as independently as possible."

---

### Finding 8: Hypothesis-Driven Backlog and Discovery/Delivery Integration

**Evidence**: OKRs do not tell teams what to build -- they tell teams what behavior to change. Features become "solution hypotheses" -- testable guesses about how to achieve the behavior change. Teams brainstorm solutions, frame them as hypotheses ("We believe [solution] will achieve [outcome]"), then divide sprint time between discovery (validating hypotheses) and delivery (building validated solutions).

**Analysis**: This is the bridge between OKRs and backlog management. The process:

1. **OKR defines the target behavior change** (key result)
2. **Team brainstorms solution hypotheses** -- features that might cause the behavior change
3. **Hypotheses enter the backlog** alongside discovery work
4. **OKRs filter the backlog**: for every existing work item, ask "Will this help achieve one of our key results?" If not, deprioritize.
5. **Early sprints favor discovery** (customer interviews, experiments, data analysis)
6. **Later sprints favor delivery** as hypotheses are validated or invalidated
7. **Learning informs prioritization** continuously

**Anti-pattern**: Creating OKRs to fit existing backlog items. Teams must use OKRs as filters, not justifications for pre-planned work.

---

### Finding 9: Integration with User Story Mapping

**Evidence**: User story mapping (per Jeff Patton's method) connects directly to OKR creation. Every item in a user story map is written as a "short action phrase" representing a customer behavior. Teams evaluate which behaviors are "crucial to the success of the user journey and are strategically important to the company" -- these become candidate key results. The story map's backbone identifies behaviors; OKRs quantify the desired change in those behaviors.

**Source**: [Gothelf Blog: OKRs and User Story Mapping](https://jeffgothelf.com/blog/okr-and-user-story-mapping/) - Accessed 2026-03-06

**Confidence**: Medium-High

**Verification**: [Dan Lebrero Book Notes](https://danlebrero.com/2024/07/09/who-does-what-by-how-much-book-summary/), [Gothelf Blog: The OKR Cycle](https://jeffgothelf.com/blog/the-okr-cycle/)

**Analysis**: The connection between user stories and outcomes follows this chain:

```
Customer Journey Narrative
    |
    v
User Story Map (behaviors as verb phrases)
    |
    v
Strategic Filter: Which behaviors are critical + strategically important?
    |
    v
Candidate Key Results: [Who] [Does what] [By how much]
    |
    v
Release Slicing: "good, better, best" exercise for MVP planning
```

The book recommends using "customer journey storytelling" to identify important behaviors. Teams extract "[who][does what]" patterns from the narrative, use story mapping to identify obstacles, and translate validated behaviors into measurable outcomes.

**Key insight for AI product owner**: When writing user stories, the agent should embed the outcome hypothesis directly. Instead of "As a user I want X so that Y," the format becomes: "We believe that enabling [user] to [action] will result in [measurable behavior change]. We will know this is true when [who] [does what] [by how much]."

### Finding 10: Outcome Mapping -- Features to Behaviors to Business KPIs

**Evidence**: Gothelf provides a facilitated mapping exercise that creates transparency between impact metrics and team-level outcomes: (1) Map customer behaviors underneath each impact metric through collaborative brainstorming, (2) Identify secondary outcomes that drive primary ones, (3) Vote on priorities to select 5-10 outcomes matching available teams, (4) Establish baselines and goals for measurable tracking.

**Analysis**: The mapping exercise transforms abstract business targets into concrete behavioral metrics:

```
Business KPI (Impact)
    Example: "Increase quarterly revenue by 15%"
        |
        v
    Which customer behaviors drive revenue?
        |
        +-- Users complete purchases from recommendations (conversion)
        +-- Users add items to cart per visit (engagement)
        +-- Users return within 7 days (retention)
        +-- Users refer friends (acquisition)
        |
        v
    Secondary behaviors (leading indicators of the above):
        |
        +-- Users browse recommendation pages (precursor to purchase)
        +-- Users save items to wishlists (precursor to cart)
        +-- Users enable push notifications (precursor to return)
        |
        v
    Team OKR: "[Specific user segment] [specific behavior] [measurable change]"
```

Revenue is not a strategic goal in itself -- it is a lagging indicator. The strategic work is identifying which specific customer behaviors, if changed, will predictably move the revenue number.

### Finding 11: The Lean UX Hypothesis Template

**Evidence**: Gothelf's Lean UX Canvas provides a complementary hypothesis structure: "We believe that [doing this/building this feature/creating this experience] for [these people/personas] will achieve [this outcome]. We will know this is true when we see [this market feedback, quantitative measure, or qualitative insight]." Outcomes serve as the success criteria for hypotheses (Box 2 of the canvas maps to Box 6).

**Confidence**: High

**Verification**: [Gothelf Blog: Connecting Lean UX, Sense & Respond, and OKRs](https://jeffgothelf.com/blog/connecting-lean-ux-sense-respond-and-okrs-a-customer-centric-journey/), [Airfocus Interview](https://airfocus.com/blog/customer-centricity-okrs-jeff-gothelf/), [Dan Lebrero Book Notes](https://danlebrero.com/2024/07/09/who-does-what-by-how-much-book-summary/)

**Analysis**: The Lean UX hypothesis template bridges the gap between OKRs and individual backlog items. Where OKRs define the target (behavior change), hypotheses define the proposed solution and its expected effect. The "We will know this is true when..." clause directly uses the [Who][Does what][By how much] formula as the validation criterion.

**Combined template for requirements**:
```
Objective: [Qualitative, inspirational, timeboxed goal]

Key Result: [Who] [Does what] [By how much]

Hypothesis: We believe that [feature/solution] for [user segment]
            will achieve [key result].
            We will know this is true when we see
            [who] [does what] [by how much].

Measurement: [Leading indicator] predicts [lagging indicator]
Baseline: [Current metric value]
Target: [Desired metric value]
```

---

### Finding 12: Common Anti-Patterns

**Evidence**: The book identifies seven key anti-patterns: (1) Writing key results as task lists, (2) Retrofitting OKRs to existing backlogs, (3) Measuring system behavior instead of customer behavior, (4) Sandbagging metrics (under-promising), (5) Cascading OKRs top-down instead of aligning via parent OKRs, (6) Tying individual OKRs to performance evaluation, (7) Hyperlocal optimization without cross-team collaboration.

**Source**: [Dan Lebrero Book Notes](https://danlebrero.com/2024/07/09/who-does-what-by-how-much-book-summary/) - Accessed 2026-03-06

**Confidence**: High

**Verification**: [Gothelf Blog: OKR Anti-Pattern](https://jeffgothelf.com/blog/okr-anti-pattern-creating-okrs-to-fit-your-backlog/), [MindTheProduct Interview](https://www.mindtheproduct.com/why-most-companies-struggle-with-okrs-a-conversation-with-jeff-gothelf/), [CX Wheel Review](https://cxwheel.substack.com/p/16-who-does-what-by-how-much-gothelf-seiden)

**Analysis**: The most common failure mode is teams listing outputs as key results: "Launch mobile app" instead of "Mobile users complete checkout 40% more often." The second most common is adapting OKRs to justify pre-existing work rather than using OKRs to filter and reprioritize.

**Anti-pattern detection rules for an AI agent**:

| Signal | Anti-Pattern | Correction |
|--------|-------------|------------|
| KR starts with "Launch", "Build", "Ship", "Deploy" | Output disguised as outcome | Rewrite as behavior: "Users [do what] [by how much]" |
| KR has no customer/user subject | Missing the "Who" | Add explicit user segment |
| KR has no numeric target | Missing the "By how much" | Add baseline and target |
| KR measures system metrics (uptime, latency) | System behavior, not customer behavior | Translate to user-facing impact |
| OKR matches existing backlog 1:1 | Backlog retrofitting | Challenge: "Does this change behavior?" |

**Note on source tier**: The book itself is the primary source. Since it is a commercially published book and not open-access web content, the research relies on the authors' own blog posts (medium-high tier as author-primary publications) and multiple independent book summaries/reviews for cross-referencing. No high-tier academic sources exist for this topic as it is a practitioner framework, not an academic one.

---

## Knowledge Gaps

### Gap 1: Detailed Template Worksheets from the Book

**Issue**: The book reportedly contains printable worksheets and step-by-step facilitation guides for running OKR workshops. These are not available in online summaries or reviews.

**Attempted**: Searched author blog, book summary sites, podcast transcripts, publisher site (okr-book.com).

**Recommendation**: Obtain a copy of the physical book (ISBN: 978-1732818446) for the complete worksheet set. The "OKR Repair Kit" free email course on the author's site may contain supplementary templates.

### Gap 2: Quantitative Validation of the Framework

**Issue**: No empirical studies measuring the effectiveness of customer-centric OKRs vs. traditional OKRs were found. The framework is based on practitioner experience, not controlled research.

**Attempted**: Searched for academic papers, case studies with before/after metrics, controlled comparisons.

**Recommendation**: Treat the framework as expert practitioner methodology (medium-high confidence) rather than empirically validated theory.

### Gap 3: Non-Tech Industry Application Details

**Issue**: The book claims applicability to HR, finance, legal, and marketing teams. Detailed examples for non-tech contexts were limited in available sources.

**Attempted**: Searched for non-tech OKR examples from the book, industry-specific reviews.

**Recommendation**: The core formula is domain-agnostic, but domain-specific examples would strengthen agent implementation for non-product teams.

## Conflicting Information

### Conflict 1: Number of Core OKR Principles

**Position A**: Six core principles (Focus, Autonomy, Alignment, Accountability, Transparency, Agility) -- Source: [CX Wheel Review](https://cxwheel.substack.com/p/16-who-does-what-by-how-much-gothelf-seiden), Reputation: Medium

**Position B**: Seven core principles (the six above plus Customer-centricity as the seventh) -- Source: [Dan Lebrero Book Notes](https://danlebrero.com/2024/07/09/who-does-what-by-how-much-book-summary/), Reputation: Medium-High. Also confirmed by [Sandor Dargo Review](https://www.sandordargo.com/blog/2024/10/19/who-does-what-by-how-much), Reputation: Medium.

**Assessment**: The Dan Lebrero source provides the most detailed and comprehensive book summary with chapter-level specificity. Two independent sources confirm seven principles. The CX Wheel review likely omitted customer-centricity because it considers it implicit rather than a separate principle. **Adopted: seven principles.**

## Practical Takeaways for AI Product Owner Agent Integration

### 1. Requirement Generation Template

Every requirement generated by the agent should include:

```
## Requirement: [Title]

### Objective
[Qualitative, inspirational, timeboxed statement]

### Measurable Outcome (Key Result)
[Who]: [Specific user segment]
[Does what]: [Observable, measurable behavior]
[By how much]: [Numeric target with baseline]

### Hypothesis
We believe that [proposed solution/feature]
for [user segment]
will achieve [the key result above].
We will know this is true when we see
[who] [does what] [by how much].

### Outcome Map
Impact (Business KPI): [e.g., Revenue, Retention, NPS]
  <- Outcome (Behavior): [The key result]
    <- Output (Feature): [What the team will build]

### Leading Indicators
- [Secondary behavior 1 that predicts the outcome]
- [Secondary behavior 2 that predicts the outcome]

### Measurement Plan
- Baseline: [Current value]
- Target: [Desired value]
- Tracking method: [How to measure]
- Check-in cadence: Weekly status, Monthly review
```

### 2. Anti-Pattern Detection Rules

The agent should validate generated requirements against these rules:

1. **Every key result must have a "Who"** -- reject requirements without an explicit user segment
2. **Every key result must be a behavior** -- reject verbs like "launch", "build", "ship", "deploy"
3. **Every key result must have a "By how much"** -- reject requirements without numeric targets
4. **Customer behavior, not system behavior** -- reject metrics like uptime, latency, throughput unless translated to user impact
5. **No backlog retrofitting** -- when an existing feature request is the input, challenge whether it actually changes behavior

### 3. Outcome Mapping Automation

The agent should maintain a three-tier map:

```
Business KPIs (Impact)
    |-- Revenue growth
    |   |-- Outcome: Users complete purchases [by X%]

### 4. Story-to-Outcome Traceability

Every user story should trace back to a measurable outcome:

```
User Story: "As a [user], I want [feature] so that [benefit]"
    |
    Maps to Key Result: [Who] [Does what] [By how much]
    |
    Maps to Objective: [Qualitative goal]
    |
    Maps to Business KPI: [Impact metric]
```

If a story cannot be traced to a measurable outcome, it should be flagged for review.

## Recommendations for Further Research

1. **Lean UX Canvas Deep Dive**: Research the full 8-box Lean UX Canvas to integrate hypothesis-driven development into the agent's workflow (the canvas connects business problems to testable hypotheses with outcome-based success criteria).
2. **HEART Framework Comparison**: Compare Google's HEART framework (Happiness, Engagement, Adoption, Retention, Task success) with the Gothelf/Seiden approach to identify complementary metrics categories.
3. **North Star Metric Integration**: Research how the "North Star Metric" concept (Amplitude/Sean Ellis) relates to the logic model's "Impact" tier and whether it can serve as the top-level anchor for outcome mapping.
4. **Pirate Metrics (AARRR) Mapping**: Research how Dave McClure's Acquisition-Activation-Retention-Referral-Revenue framework maps to the leading/lagging indicator hierarchy.
