INTRODUCTION

English translation pending.

CORE DEFINITION

The Internal-External Matrix positions business units on two axes: the total weighted internal factor evaluation score, which summarizes internal strengths and weaknesses, and the total weighted external factor evaluation score, which summarizes opportunities and threats. Each axis is divided into high, medium, and low bands, producing nine cells grouped into three strategy regions. Cells in the grow and build region favor intensive and integrative strategies. Cells in the hold and maintain region favor market penetration and product development. Cells in the harvest or divest region favor retrenchment and divestiture. The matrix assumes both weighted scores are meaningful summaries.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Use score integration: compute weighted internal and external scores before locating the unit. - Use region lookup: read the strategy family from the cell rather than choosing by preference. - Use portfolio view: plot all units together to see which deserve investment and which should be exited.

Anchor fast decisions

Internal capability and external environment constrain strategy jointly, and firms often optimize for one while ignoring the other. Reducing each side to a weighted score forces the factors and their weights to be stated, which makes the judgment inspectable. Plotting units on both axes then groups them into strategy families with different resource implications, so portfolio decisions become comparisons across units rather than isolated cases. The weakness is inherent in the input, since a subjective weighting produces a precise-looking placement resting on judgment.

Gap Analysis

Gap analysis in management refers to the difference between ideal performance (or potential performance) and actual performance. It can be conducted for an organization or a product. Organizational gap analysis identifies the gap between optimal resource allocation and current allocation, revealing areas for improvement. It involves identifying the gap between business needs and current capabilities, documenting it, and making improvements. As long as expectations for performance in an industry are known, the gap between a company's current performance and ideal performance can be compared; this difference is gap analysis. Similar analysis can be conducted at strategic or operational levels. Gap analysis can be applied at various levels, such as: organization (e.g., human resources), operational direction, business processes, information technology, and compliance with specific standards. Gap analysis can be used to determine the time, money, and manpower needed to achieve a specific goal (e.g., transitioning a payroll process from paper-based to paperless electronic workflow).
