NEED-BASED DECISION SCIENCE

Decide which needs truly justify resources before choosing what to build, improve, or abandon.

The discipline structures decisions around the relevance of needs to increase the organization’s capacity to create, preserve, and capture value without disproportionately increasing business complexity.

The Problem

Options are abundant. Resources are not.

Customers ask for improvements, teams propose projects, competitors launch new offerings, and technology expands the space of possibilities. The strategic challenge is to prevent possibility from being confused with priority.

Reasoning that creates dispersion

“There is a need. Therefore, there is an opportunity. Let’s build a solution.”

Need-Based reasoning

“There is a need. How relevant is it, who does it matter to, and does it justify resources now?”

A Need is not a priority. A priority is not an opportunity. And a good solution does not fix a strategically irrelevant need.

Principles

Seven rules to decide before executing.

01. A Need does not mean an opportunity

The existence of a need only places it in the universe of analysis. It still has to justify attention and resources.

02. Relevance comes before solution

Before discussing a feature, product, or initiative, you need to understand how relevant the need is to the analyzed base.

03. Core requires shared relevance

A need limited to a small portion of the customer base should not automatically be treated as a foundation of the Core.

04. Innovation also starts with the Need

Building first and then trying to create relevance shifts risk to the most expensive stage of the decision.

05. Prioritizing is allocating

Every choice consumes capital, time, executive attention, and operational capacity that are no longer available for other needs.

06. Complexity has a cost

New audiences, promises, channels, and processes can create new needs and expand the system the business has to manage.

07. Value is the objective

The ultimate direction is to increase the capacity to create, preserve, and capture value without disproportionately increasing complexity.

From Need to Decision

The need comes first. The solution comes later.

The method reduces a broad universe of needs until it reaches those that deserve strategic treatment.

01. Discover

Identify Needs without starting from a predefined solution.

02. Select

Define what makes sense to investigate further given the organization’s context.

03. Prioritize

Understand which needs are shared and relevant across the customer base.

04. Measure

Use ICAN among those who actually prioritized the need.

05. Decide

Translate evidence into choices about resources, Core, Leverage, and direction.

Fundamental Distinctions

Four concepts that must not be confused.

Need

An identified need. Its existence does not determine strategic importance.

Priority

A need that, given the evidence and context, deserves comparative attention.

Opportunity

A possible course of action that should only move forward when there is enough evidence to justify resources and risk.

Complexity

The additional system a decision requires to be created, delivered, maintained, and monetized over time.

Conceptual System

Discipline, concepts, and applications are distinct.

Need Gap

Shows where the priority assumed by the company is misaligned with relevant needs.

Need-Based Value Matrix

Connects relevant needs to the value creation, delivery, perception, and capture chain.

Strategic Complexity

Helps assess the structural cost of prioritization choices and their capacity to create dispersion.

Quick Answers

The essentials of Need-Based Decision Science.

What is Need-Based Decision Science?

It is the discipline created by George Eich to structure decisions and resource allocation around relevant market needs, with the goal of increasing the organization’s capacity to create, preserve, and capture value without disproportionately increasing its complexity.

Is every Need an opportunity?

No. A need can be real and still have low relevance for the analyzed base. Need, priority, and opportunity are different concepts.

What is the central difference of the approach?

It prioritizes evidence about the relevance of needs before choosing solutions, projects, or investments.

How is the discipline applied in companies?

The Strategic Prioritization Study applies the discipline to a company’s customer base to support resource-allocation decisions.

What decision does your company need to make?

Before the solution, validate the need.

The Strategic Prioritization Study applies Need-Based Decision Science to your own customer base to support decisions on investment, product, innovation, and positioning.
