Task analysis is a systematic approach to understanding how work is actually performed, identifying hazards, and developing targeted safety interventions. It's an essential tool for any comprehensive workplace safety program.

What is Task Analysis?​

Task analysis breaks down a job into individual tasks and subtasks, examining:

  • The sequence of actions required
  • Tools and equipment used
  • Physical and cognitive demands
  • Potential hazards at each step
  • Opportunities for improvement

Task Analysis vs. Job Analysis​

While related, these serve different purposes:

Job Analysis: Broad overview of a position's responsibilities, qualifications, and general requirements

Task Analysis: Detailed examination of specific tasks within a job, focusing on how work is performed

When to Conduct Task Analysis​

Prioritize task analysis for:

  • Jobs with high injury rates
  • New processes or equipment
  • Tasks involving hazardous materials
  • Complex multi-step procedures
  • Jobs with high turnover
  • Positions requiring specialized training

The Task Analysis Process​

Step 1: Select the Task​

Choose tasks that are critical, frequent, or high-risk.

Step 2: Break Down the Task​

Identify each step in the process. Observe multiple workers to capture variations in technique.

Step 3: Identify Hazards​

For each step, ask:

  • What could go wrong?
  • What are the ergonomic risks?
  • What environmental factors are present?
  • What training is required?

Step 4: Assess Risk​

Evaluate the likelihood and severity of potential injuries for each identified hazard.

Step 5: Develop Controls​

Apply the hierarchy of controls:

  1. Elimination
  2. Substitution
  3. Engineering controls
  4. Administrative controls
  5. Personal protective equipment

Step 6: Document and Implement​

Create clear documentation and train workers on safer methods.

Practical Applications​

Job Safety Analysis (JSA)​

A specific type of task analysis focused on identifying hazards and establishing safe work procedures.

Standard Operating Procedures (SOPs)​

Task analysis provides the foundation for developing clear, safe SOPs.

Training Programs​

Understanding task components helps create effective training that addresses actual job demands.

Ergonomic Improvements​

Detailed task analysis reveals opportunities for ergonomic interventions.

Involving Employees​

The workers who perform tasks daily have invaluable insights. Involve them by:

  • Observing experienced workers
  • Conducting interviews
  • Facilitating group discussions
  • Testing proposed changes with frontline staff

Common Mistakes to Avoid​

  • Analyzing tasks in isolation without considering workflow
  • Relying solely on supervisor input without observing actual work
  • Making the analysis too complex or detailed
  • Failing to update analysis when processes change
  • Not communicating findings to workers

Integrating with Other Safety Tools​

Task analysis complements:

  • Physical demands analysis
  • Ergonomic assessments
  • Risk management programs
  • Incident investigations
  • Continuous improvement initiatives

Measuring Success​

Track these indicators:

  • Reduction in task-specific injuries
  • Improved efficiency
  • Decreased error rates
  • Employee feedback on task modifications
  • Training effectiveness

Task analysis is an investment in understanding your workplace at a granular level. The insights gained drive targeted improvements that make work safer and more efficient.
