## Short Definition

Data are recorded facts about events or entities that can be analyzed to create information and decisions.

## 一言でいうと

Data are recorded facts about events or entities that can be analyzed to create information and decisions.

## 意味

Data consist of raw observations such as numbers, text, images, or signals collected from processes and systems. By themselves, data may lack meaning until they are organized, cleaned, and interpreted in context. Defining what data to collect, how it is measured, and how it is governed is a strategic decision that affects quality, privacy, and insight.

## 役立つ場面

It determines what to collect and how to measure it to answer real questions. It influences governance rules such as ownership, access, and retention. It affects downstream analytics quality by shaping accuracy and completeness.

## 使い方のポイント

- Define data with clear units, sources, and collection rules.
- Separate raw data from derived metrics to avoid confusion.
- Prioritize quality and relevance over sheer volume.
- Document metadata so others can interpret the data correctly.
- Respect privacy and ethical constraints at the point of collection.

## よくある誤解 / 落とし穴

- Data are not automatically objective; collection choices add bias.
- More data does not guarantee better decisions without context.
- Data are not the same as information or insight; processing is required.

## 最小例

A retailer wants to understand repeat purchases. The team defines a customer identifier, captures transaction timestamps, and logs product categories. They add metadata for time zones and data sources to avoid misinterpretation. With clean data, analysts can calculate repeat rate and segment behavior, while privacy rules control access to personal identifiers.

## FAQ

### When should I use Data?

Use it when the team needs to decide scope, priority, owner, or trade-off, not when it only needs a short definition.

### What makes Data useful in practice?

It becomes useful when it is tied to evidence, a decision owner, and a concrete next operating choice.

### What should I avoid?

Avoid using the term as a label without clarifying assumptions, boundaries, and how success will be judged.
