ROI【🔏Confidential File】 No. X029 | What is Jobs-to-be-Done Theory

Detective Notes: The final mystery left by Clayton Christensen - "Jobs-to-be-Done Theory." While many understand it merely as a "customer needs analysis method," its true identity is "a blueprint for converting human desire for progress into products and services." Why is a milkshake hired for morning commutes, and why do people buy holes, not drills? And why do so many companies remain trapped by demographic data, missing the real reasons behind purchases? Uncover the intertwined truth of emotion and function that separates "hired products" from "abandoned products."

What is Jobs-to-be-Done Theory - Case Overview

Jobs-to-be-Done Theory, formally known as "The systematic theory for understanding why customers hire products and services," was presented as a culmination work by Harvard Business School's Clayton Christensen in 2016. Based on the fundamental insight that customers don't purchase products but "hire" them to make progress in specific life situations, this framework is recognized among our clients as a systematic approach to discovering true customer needs. However, in actual practice, it's often superficially applied as "more detailed customer research methodology," with most companies failing to understand the original revolutionary value of the relationship between human desire for progress and innovation creation.

Investigation Notes: Revolutionary product design through understanding customer "hiring reasons." Seemingly simple, but behind it lies deep human understanding: "humans constantly seek better lives" and "products are merely means to progress." Why the expression "hiring," and we need to decode the comprehensive job structure including emotional and social aspects.

Basic Structure of Jobs Theory - Evidence Analysis

Primary Evidence: Four-Layer Job Structure

Functional Job

"Achieving practical and pragmatic progress"
・Clearly definable tasks and problem-solving
・Measurable results and outcomes  
・Improving efficiency and effectiveness
・Reducing time, effort, and costs

Examples:
・Transportation from Point A to Point B (transportation)
・Satisfying hunger (food products)
・Information collection, organization, communication (IT tools)
・Maintaining cleanliness (cleaning supplies)

Emotional Job

"Improving psychological and emotional states"
・Enhancing mood and emotions
・Reducing anxiety and stress
・Gaining confidence, pride, and satisfaction
・Securing peace of mind and safety

Examples:
・Luxury brands → Gaining social status and confidence

・Pets → Healing and emotional fulfillment
・Insurance → Reducing future anxieties

Social Job

"Building relationships and social status with others"
・Managing impressions and evaluations
・Expressing belonging and identity
・Building, maintaining, improving relationships
・Performing social roles

Examples:
・Fashion → Self-expression and impression management

Circumstantial Elements (Context)

"Specific context where jobs arise"
・Time, place, environment
・Constraints, limitations, conditions
・Other people and relationships
・Emotional and psychological states

Important contextual questions:
・When and where does this job occur?
・What constraints exist during this job?
・Who is present during this job situation?
・What emotional state drives this choice?

Evidence Analysis: The innovation of Jobs Theory lies in focusing not on product features but on "jobs within the customer's life context," thereby discovering previously overlooked competitive relationships and improvement opportunities.

Jobs Theory Implementation Process - Investigation Methods

Investigation Discovery 1: Classic Case Analysis (The Milkshake Mystery)

Case Evidence (Fast food restaurant milkshake sales improvement):

Traditional Analysis Approach:
・Customer segmentation: Classification by age, gender, income
・Product improvement: Adjusting taste, price, size
・Competitive analysis: Comparison with other restaurants' milkshakes
→ Result: Only marginal improvements, no dramatic sales increase

Jobs Theory Analysis:
Phase 1: Job Discovery
・Detailed observation of purchase situations
・Customer interviews: "Why did you choose a milkshake?"

Phase 2: Job Identification
Discovered Jobs:
Functional Job:
- One-handed consumption providing satiety during long commutes
- Convenient nutrition intake as breakfast substitute
- Safe consumption while driving

Emotional Job:
- Enjoyment and comfort during boring commute time
- Guilt-free small morning luxury
- Energy and mood boost for starting the day

Social Job:
- Expressing values that prioritize enjoyment over excessive health focus
- Casual and approachable image projection

Contextual Elements:
- Morning commute hours (7-9 AM)
- Car travel (one-hand usage limitation)
- Solo consumption (no family/colleague observation)
- Competition with other breakfast options

Phase 3: Competitive Redefinition
Traditional perception: Other restaurants' milkshakes
Actual competition:
・Bananas (one-handed but insufficient satiety)
・Donuts (messy hands, difficult in-car consumption)
・Breakfast bars (bland, lacks enjoyment)

Step 2: Job Interview Implementation
Important Question Patterns:
・"When was the last time you purchased/used X, and what was the situation?"
・"What other options did you consider at that time?"
・"Why did you ultimately choose X?"
・"What progress did you achieve by using X?"
・"If X wasn't available, what would you have done instead?"

Step 3: Job Structuring
Three-layer organization (functional, emotional, social):
・What (function): What specifically do you want to achieve?
・Feel (emotion): What emotional state do you seek?
・Image (social): How do you want to be perceived by others?

Step 4: Competitive Redefinition
・Functional competition: Products/services providing same function
・Time competition: Alternative actions chosen in same time frame
・Budget competition: Competing spending choices in same budget frame

Step 5: Solution Design
・Product/service design maximizing job achievement
・Eliminating obstacles and dissatisfaction in job performance
・Securing clear advantages over competition

Conclusion - Investigation Summary

Final Investigation Report:

Jobs-to-be-Done Theory represents "a blueprint for understanding the true reasons customers hire products and converting human desire for progress into innovation." This revolutionary framework, left as Clayton Christensen's culmination work, functions as a system demanding fundamental transformation of traditional marketing and product development approaches.

The most impressive discovery in this investigation was Jobs Theory's "competitive redefinition power." Just as the milkshake's true competition was bananas and donuts, discovering competitive relationships beyond traditional industry classifications and product categories creates entirely new innovation opportunities and differentiation strategies. This unique insight stems from Jobs Theory's "customer life context" starting point.

The three-layer structure of functional, emotional, and social jobs enabling comprehensive product and service value design also emerged as a crucial finding. While many companies focus solely on functional value, understanding jobs that include emotional and social aspects achieves deeper customer satisfaction and stronger differentiation.

However, the challenge of job discovery difficulty also became apparent. Customers often cannot clearly articulate their true jobs themselves, creating high risk of missing essence through superficial interviews and surveys. Continuous observation, deep empathy, and insight to detect contradictions between actions and words are essential.

The integration possibilities with other business frameworks proved noteworthy. Jobs Theory functions as a foundation that dramatically improves accuracy and effectiveness of other methods, including customer understanding through Empathy Maps, business model design with Lean Canvas, and growth metrics setting via AARRR.

Universal applicability across industries was confirmed as an important characteristic. Various fields including SaaS, education, and healthcare demonstrate gaps between surface needs and actual jobs, proving that job-based approaches bring dramatic improvements.

The most crucial discovery was that Jobs Theory functions as "human-centered innovation philosophy" beyond mere "customer research methodology." Customers don't desire products; they seek better lives. This fundamental insight enables human-centered rather than technology-centered innovation.

Customer Hiring Maxim: "Customers aren't buying products. They're hiring products as means to achieve better lives."
