Guidelines for Clarity and Precision: Technical Documentation Standards

---

1. Introduction

In technology-intensive industry environments, high-quality documentation and code form the essential infrastructure for knowledge transfer and collaborative development. As technical complexity continually increases, clear, accurate, and consistent documentation has become an indispensable component of engineering practice.

Studies have shown that effective technical documentation significantly reduces the cost of knowledge acquisition, minimizes understanding discrepancies, and enhances the productivity of project participants.

This study systematically explores the theoretical foundations and practical strategies of technical documentation writing from the interdisciplinary perspectives of linguistics, cognitive science, and software engineering. By establishing a standardized technical writing framework, this paper aims to help readers master:

1. Methodologies for conveying concepts and logic clearly, accurately, and objectively in the technical domain.
2. Standardized writing specifications and best practices for English technical documentation.
3. Effective communication strategies tailored for audiences with diverse technical backgrounds.

2. Vocabulary Management and Terminology Standardization

2.1 Principle of Terminology Consistency

The unified use of terminology is fundamental to ensuring the professionalism and comprehensibility of technical documentation. Research indicates that inconsistent terminology leads to increased cognitive load for the reader. Technical documentation must adhere to the following principles:

• Terminology Reuse Priority: Avoid creating new synonyms for established professional terms. Prioritize terminology recognized within the domain.
• Glossary Development: When documentation contains a high volume of specialized terms, a systematic Glossary should be constructed.
• Absolute Consistency: The term name and its abbreviation must remain absolutely consistent for the same concept throughout the document, avoiding the ambiguity caused by synonymous replacement.

2.2 Abbreviation Standards and Management

Abbreviations, as simplified forms of terms, must adhere to strict guidelines:

First Appearance Rule: When a term appears for the first time, its full name should be presented in bold, with the abbreviation indicated in parentheses.

Frequency Judgement: An abbreviation should only be considered if it significantly simplifies the expression AND the term appears frequently within the document.

2.3 Pronoun Usage Strategies

The use of pronouns (such as "it," "they," "this") requires particular caution to avoid ambiguity:

• Immediate Proximity: A pronoun should appear immediately after the noun it replaces.
• Distance Limitation: If a pronoun is separated from its antecedent noun by more than 5 words, the original noun should be repeated.
• Avoid Multiple Antecedents: When a second potential referent appears between the noun and the pronoun, avoid using the pronoun to eliminate ambiguity.

From a cognitive load theory perspective, inappropriate pronoun use is analogous to a "null pointer exception" in programming, where readers cannot accurately locate the referred object.

3. Voice Selection and Expressive Accuracy

3.1 Prioritized Application of Active Voice

Linguistic research indicates that the active voice is more effective than the passive voice in conveying information and reducing the reader's cognitive burden.

• Clear Identification: The active voice explicitly identifies the performer of the action.
• Concise Expression: The active voice is usually more concise than its passive counterpart.
• Prevention of Data Loss: The passive voice often omits the agent, potentially leading to the loss of critical information.

3.2 Appropriate Use of Passive Voice

While the active voice is the priority, the passive voice may be more appropriate when:

• The agent is unknown or irrelevant.
• The recipient of the action or the result needs emphasis.
• Conforming to the expressive conventions of a specific domain.

3.3 Verb Choice and Expressive Precision

The verb is the core of the sentence. Avoid general, vague words such as "is," "has," or "happen."

4. Sentence Construction and Information Organization

4.1 Principle of Concise Sentence Structure

Cognitive psychology research shows that short sentences are easier for readers to understand and remember. Technical documentation should adhere to:

• Single Point Principle: Each sentence should express only one core point.
• Clause Control: Limit the number and depth of nested clauses.
• Modifier Restraint: Use adjectives and adverbs sparingly, retaining only the modifying components necessary for objective information.

4.2 Structured Application of Lists and Tables

4.2.2 List Structure Guidelines

Convert multiple items enumerated within a sentence into a formatted list to improve readability.

Ordered List Format

Items in an ordered list should begin with an imperative verb, clearly indicating the action step:

4.2.3 Table Design Principles

• Clear Column Headers: Every column should have a clear header reflecting the data attribute.
• Concise Cells: Table cell content should be brief and clear.
• Data Type Consistency: Data within the same column should maintain type consistency.

5. Paragraph Construction and Document Structure

5.1 Principles of Paragraph Organization

• Topic Sentence Guidance: The first sentence should summarize the core theme.
• Thematic Focus: Avoid thematic drift or mixture within a single paragraph.
• Moderate Length: Ideally 3–5 sentences, and no more than 7.
• Information Completeness: Address "What," "Why," and "How."

5.2 Overall Document Architecture

Organize content according to the reader's cognitive path rather than the system's internal structure. An example outline aligning with cognitive logic:

6. Audience Analysis and Document Adaptability

6.1 Audience-Oriented Writing Methodology

The effectiveness of technical documentation can be expressed by the following formula:

Document Effectiveness = Knowledge Required for Reader to Complete Task – Reader's Existing Knowledge

To bridge this gap, three steps are necessary:

1. Reader Persona Building: Define technical background and expertise level.
2. Knowledge Level Assessment: Evaluate familiarity with domain concepts.
3. Explicit Learning Objectives: State the specific skills readers will gain.

6.2 Cross-Cultural and Linguistic Adaptability

In a globalized technology environment:

• Linguistic Simplification: Prioritize simple, common vocabulary.
• Cultural Neutrality: Avoid idioms, slang, or metaphors specific to certain cultures.
• Translation Friendliness: Avoid structures that could lead to ambiguity during translation.

7. Punctuation and Formatting Standards

7.1 Principles of Punctuation Usage

• Intra-sentence Punctuation: Commas, semicolons, and colons should be followed by a single space, with no space preceding them.
• End-of-Sentence Punctuation: Periods and question marks should be followed by a single space.
• Quotation Marks and Parentheses: Space added on the outside, but no space on the inside.

7.2 Mixed Language Formatting Standards

In mixed-language texts (e.g., Code mixed with English prose):

• Spacing: Spaces should be added between standard text, numbers, and symbols to improve readability.
• Quotations: Use standard English quotation marks ("") in English text.

8. Conclusion

This study systematically articulates the theoretical basis and practical standards for technical documentation writing. A complete technical writing framework has been established across multiple dimensions.

Key Recommendations Summary:

Dimension	Key Standard
Terminology	Maintain consistency; standardize abbreviations.
Voice/Verbs	Prioritize active voice; select precise verbs.
Sentences	One point per sentence; minimize modifiers.
Structure	Topic-led paragraphs; logical document architecture.
Audience	Adapt content depth to reader knowledge levels.

Technical documentation writing is an indispensable skill in engineering practice. By continuously improving writing practices, technical professionals can share knowledge more effectively, foster collaboration, and provide a solid knowledge foundation for technological innovation.
