Lesson 3: Purposes, Readers and Principles of Technical Writing
Lesson Objectives
01 Determine the purposes of technical writing.
02 Identify the readers / audience of technical writing.
03 Determine the basic principles of good technical writing.
Engagement / Diagnostic Activity: Word‐Pair Analogies
Purpose: Activate prior knowledge on relationships & functions—an essential skill in analyzing the purpose and audience of any text.
Format: A :: B means “A is to B as ____”
Items & Expected Matches
1. ballpen : writing :: scissors : cutting
2. gloves : hands :: shoes : feet
3. scalpel : doctor :: chalk : teacher
4. house : shelter :: memory card : storage
5. cellphone : communication :: vehicle : transportation
Pedagogical insight: Each analogy stresses the tool–function or object–purpose relationship, mirroring the way writers must link document to reader need in technical communication.
Purposes of Technical Writing
Technical writing is functional; every sentence should enable a reader to perform, decide, or understand something technical.
Information for Task Completion & Decision-Making
Delivers clear, actionable data (e.g., step-by-step instructions, procedural manuals).
Significance: Reduces errors, saves time, and ensures safety when performing tasks.
Analysis of Events, Systems, & Implications
Investigates causes of success/failure in domains such as education, socio-economics, or politics.
Drives change by presenting evidence-based recommendations.
Example: A white-paper analyzing why a supply-chain system failed and proposing restructuring.
Persuasion & Influence on Decisions
Uses logical evidence (not emotional appeal) to advocate fair labor practices, ethical standards, or adoption of new technologies.
Practical outcome: Convincing stakeholders to invest, comply, or reform policies.
Readers / Audience of Technical Writing
Knowing the reader precedes crafting the document.
Profiles
May be managers, supervisors, secretaries, engineers, scientists, sociologists, psychologists, technicians, or any discipline-specific professional.
Can be a specific individual (e.g., the QA manager) or a homogeneous group (e.g., biomedical researchers at a conference).
Why They Read
Assignment / Obligation – Preparing a report, attending a conference, fulfilling coursework.
Personal Need – Understanding an ailment, validating or refuting a theory.
Prior Knowledge Expansion – They may already be experts who require updated or specialized data for a lecture.
Information-Seeking, Not Entertainment – Efficiency and clarity outweigh stylistic flourish.
Implication for the Writer: Tailor depth, terminology, and organization according to reader expertise and purpose.
Basic Principles of Good Technical Writing
Audience Specificity
Always write with a specific reader or defined group in mind.
Ask: Who will act on this information?
Purpose Alignment
Define a singular, explicit purpose.
Ensure every section, figure, and sentence contributes to that purpose—no filler.
Precision & Clarity
Favor specific, single, concrete, familiar words.
Avoid jargon unless the audience is known to understand it; if unavoidable, define it on first use.
Aim for language that cannot be misinterpreted.
Logical Organization (First–Then–Last)
Structure information so that introduction & conclusion frame and reinforce key points.
Use headings, numbered steps, and signposts for navigability.
Professional Presentation & Formality
Format documents with consistent typography, spacing, and visual aids (tables, graphs).
Use formal tone yet remain accessible—professionalism fosters credibility.
Practical & Ethical Connections
Real-World Stakes: Technical documents often guide high-risk operations (e.g., medical procedures, engineering specs). Errors can cost \$\$ millions or endanger lives.
Ethical Responsibility: Honest reporting and clear language prevent misinformation and protect users.
Interdisciplinary Influence: Techniques overlap with academic writing, business communication, and UX design, reinforcing the universal value of clarity and audience awareness.
Quick Reference Checklist for Writers

“Be Prepared” – Concluding Reminder
Success in technical writing—and in professional life—begins with preparation: know your audience, purpose, and the principles above before typing the first word.
