Master this essential documentation concept
In process analysis, a step or action that appears in only one version of a recorded process, indicating either a unique best practice or an individual deviation from the standard.
An outlier in documentation and process analysis refers to any step, action, or element that appears exclusively in a single version of a recorded process when multiple versions are compared. Unlike common steps shared across all process variants, outliers stand apart as unique occurrences that demand closer examination to determine their value and origin.
When subject matter experts record process walkthrough videos, outlier steps often slip through unnoticed. A senior team member might casually mention a workaround they always use, or skip a verification step they consider obvious — and unless someone is watching carefully, that deviation either gets lost or quietly adopted by others who assume it belongs in the standard workflow.
The core problem with relying solely on video recordings is that outliers are nearly impossible to systematically identify across multiple recordings. You cannot easily compare step sequences between two videos the way you can scan two text documents side by side. A step that appears in only one recording stays buried in timestamp-specific footage, invisible to anyone building or auditing your official procedures.
Converting your process videos into structured SOPs changes this. When each step is documented as discrete, comparable text, your team can quickly spot where one procedure diverges from the others — flagging that outlier for a deliberate decision: is this a best practice worth standardizing, or an individual deviation that needs correction? For example, if five onboarding videos show the same sequence but one includes an undocumented approval step, a written SOP comparison surfaces that gap immediately.
Turning video walkthroughs into formal documentation gives your team the visibility to handle outliers intentionally rather than accidentally.
A documentation team discovers that three departments each have their own version of a customer onboarding process. Steps vary significantly, making it impossible to create a single authoritative SOP without understanding which differences matter.
Use outlier analysis to map all three versions side-by-side, flagging any step that appears in only one department's version as an outlier for targeted investigation.
1. Collect all three process versions in a structured format (flowchart or step list). 2. Create a comparison matrix listing every unique step across all versions. 3. Mark steps appearing in only one version as outliers. 4. Interview the team responsible for each outlier to understand its purpose. 5. Classify each outlier as a best practice, deviation, or context-specific exception. 6. Draft a unified SOP incorporating validated outliers and flagging deviations for correction.
A single authoritative SOP that reflects real-world best practices, eliminates unauthorized deviations, and reduces cross-departmental inconsistency by up to 60%.
A senior employee with 20 years of experience is retiring. Their process recordings contain several steps not found in any other team member's version, and the documentation team must determine whether these represent critical institutional knowledge.
Treat every unique step in the retiring expert's process recordings as a potential outlier worth investigating, using structured interviews to validate and document hidden expertise before it is lost.
1. Record the expert performing key processes in detail. 2. Compare their recordings against the current standard SOP and junior staff recordings. 3. Highlight all steps unique to the expert's version as outliers. 4. Conduct targeted knowledge-transfer interviews for each outlier. 5. Validate outlier steps by testing them against quality or efficiency metrics. 6. Incorporate confirmed best practices into updated SOPs with attribution notes.
Critical institutional knowledge is preserved in formal documentation, reducing knowledge loss risk and providing a measurable improvement in process quality for remaining staff.
During a regulatory audit, inspectors require proof that all employees follow the same approved procedures. A documentation review reveals that some employee process logs contain steps not in the official SOP, creating compliance exposure.
Apply outlier analysis to employee process logs to systematically identify all deviations from the approved SOP, then document remediation actions for each outlier found.
1. Gather process logs or recordings from all employees performing the audited procedure. 2. Use the approved SOP as the baseline for comparison. 3. Flag any step in employee logs that does not appear in the SOP as an outlier. 4. Categorize outliers by risk level: high (safety/compliance impact), medium (quality impact), low (efficiency variation). 5. Document all outliers in a deviation register with employee ID, date, and description. 6. Create corrective action plans for high and medium-risk outliers. 7. Update the SOP if any outliers represent approved improvements.
A complete deviation register ready for auditor review, demonstrating proactive compliance management and reducing regulatory risk with documented corrective actions.
A team of five technical writers each produces user guides for the same software feature. Reviews show inconsistent coverage of edge cases and troubleshooting steps, with some guides containing helpful steps absent from others.
Compare all five guides systematically to identify outlier content sections — steps or explanations appearing in only one writer's version — and evaluate each for inclusion in a master template.
1. Standardize all five guides into a comparable structure using a content audit spreadsheet. 2. List every distinct content element (steps, warnings, tips, troubleshooting items) across all guides. 3. Flag elements appearing in only one guide as outliers. 4. Assign a senior writer to review each outlier for accuracy and user value. 5. Approved outliers are added to the master documentation template. 6. Rejected outliers are removed and the responsible writer is coached. 7. Publish an updated style guide incorporating validated outlier content as new standards.
A comprehensive master template that captures the collective expertise of all five writers, improving documentation coverage and consistency while reducing individual review cycles.
Outlier identification is only meaningful when compared against a clear, agreed-upon standard. Before analyzing process versions for outliers, ensure your team has defined what the baseline process looks like, whether that is an existing SOP, a majority-consensus version, or a regulatory standard.
Outliers carry no inherent positive or negative value until they are investigated in context. A step that appears only once might be the most important improvement in the entire process, or it might be a dangerous shortcut. Premature classification wastes the analytical opportunity outliers provide.
Outliers discovered during one documentation cycle often resurface in future audits or new employee onboarding. Maintaining a centralized outlier register allows documentation teams to track patterns over time, spot recurring deviations, and measure whether corrective actions are working.
Documentation professionals excel at identifying and organizing outliers, but the classification decision — whether an outlier is a best practice, deviation, or exception — requires domain expertise. Partnering with SMEs ensures classifications are technically accurate and operationally realistic.
The entire value of outlier analysis is realized only when findings are translated back into improved documentation. Teams that identify and classify outliers but fail to update their SOPs, templates, or style guides lose the compounding benefit of continuous improvement.
