To assess the risk of musculoskeletal disorders associated with manual handling tasks.
- Methodologies: Engineering, Product Design, Project Management
Key Indicator Method (KIM)

Key Indicator Method (KIM)
- Continuous Improvement, Ergonomics, Human Factors, Human Factors Engineering (HFE), Lean Manufacturing, Process Improvement, Risk Analysis, Risk Management, Safety
Objective:
How it’s used:
- A method for assessing the risk of musculoskeletal disorders associated with lifting, carrying, pushing, and pulling tasks. It uses a set of key indicators to score the risk and identify areas for improvement.
Pros
- Provides a structured and systematic way to assess manual handling risks; Can be used by people with limited ergonomics expertise.
Cons
- May not be as accurate or detailed as a full ergonomic assessment; May not identify all risk factors.
Categories:
- Ergonomics, Risk Management
Best for:
- Assessing the risk of manual handling tasks in a workplace to prioritize for further ergonomic assessment.
The Key Indicator Method (KIM) is particularly adaptable in environments where physical tasks are integral, such as warehousing, construction, healthcare, and manufacturing industries. Typically implemented during the design phase of workflows or workspaces, KIM involves collaboration among various stakeholders, including safety officers, ergonomists, engineers, and employees performing manual tasks, thus ensuring that diverse perspectives contribute to the assessment process. Data generated by KIM can be employed to direct interventions, reducing ergonomic risks before they lead to injuries. Its systematic approach allows organizations lacking specialized ergonomics expertise to efficiently identify and address potential hazards using established scoring criteria, which streamlines the decision-making process regarding ergonomic interventions. As a scalable tool, KIM can be utilized for new projects or existing operations, allowing for periodic reassessment to maintain workplace safety standards. Real-world applications might involve assessing the safety of lifting procedures in a warehouse setting or evaluating the ergonomics of patient handling in healthcare facilities, ensuring that improvements align with established ergonomic principles while promoting worker health and productivity. Engaging employees in the risk assessment process via KIM fosters a culture of safety and awareness, as individuals directly involved in manual tasks can provide valuable input on their experiences, leading to more effective and accepted ergonomic solutions.
Key steps of this methodology
- Identify manual handling tasks performed in the workplace.
- Determine the frequency and duration of each manual handling task.
- Assess the load characteristics, including weight, shape, and size.
- Evaluate the working environment, including space, surface conditions, and availability of equipment.
- Score each task based on predefined key indicators such as posture, force, and repetition.
- Prioritize tasks based on the scores to identify high-risk areas.
- Analyze the scoring results to identify specific risk factors and improvement opportunities.
- Develop a plan for ergonomic interventions to mitigate identified risks.
Pro Tips
- Incorporate real-time data collection methods to improve accuracy in risk assessments, leveraging wearable technology or sensors for dynamic task analysis.
- Utilize a multi-disciplinary approach, collaborating with ergonomists, engineers, and workers to validate KIM scores and identify practical improvement strategies.
- Regularly update the key indicators based on feedback and evolving ergonomic research to ensure the methodology remains relevant and effective in assessing risks.
