Analytical method lifecycle process flowchart
An analytical method lifecycle process chart for reviewing method status, performance, changes and issues, planning action, escalating concerns and updating controlled records.
What the analytical method lifecycle process is
Lifecycle management is broader than a scheduled check. A method can be reviewed after a trend, an operational change, a recurring issue or another trigger, and the process needs to distinguish a justified continued-use conclusion from a concern that requires action.
This chart keeps that branch visible. The Method Owner and Laboratory Team assemble the relevant information, while the Quality Reviewer either approves the conclusion or sends concerns back to assessment. The result is a controlled record of both the review and the action that follows it.
What this flowchart covers
In this template
- Method Owner, Laboratory Team and Quality Reviewer lanes connect information gathering to an accountable lifecycle conclusion.
- Current intended use and status clear? prevents a review from proceeding on an uncertain method version or ownership record.
- Potential concern or opportunity identified? separates a continued-use rationale from a planned lifecycle action.
- Lifecycle conclusion approved? either updates controlled records or escalates the assessment for further work.
When to use this template
- You need one process for planned method reviews and event-driven reviews following changes, trends or recurring issues.
- Method information is spread across performance records, change controls and investigations with no visible route to a lifecycle decision.
- A laboratory needs to show how continued use, improvement work and unresolved concerns are distinguished and recorded.
How it works
List the real review triggers
Replace the opening trigger with the circumstances that initiate a review at your laboratory. Include scheduled and event-driven triggers only where your process genuinely uses them.
Connect the information sources
Add links or notes for the performance records, change records, issue logs and method versions that reviewers consult. This makes the chart a map of evidence rather than a generic meeting sequence.
Define lifecycle actions locally
Specify the possible actions and decision owners used at your site, such as further assessment, method update, restricted use or retirement. Do not treat the examples as mandatory outcomes.
Record the approved conclusion
Name the controlled records and communication route updated after the decision. Preserve the loop to assessment when a reviewer identifies unresolved concerns or needs more evidence.
Frequently asked questions
What is an analytical method lifecycle review?
It is a documented review of a method's current use, status, performance information, changes and issues to decide what should happen next. The applicable triggers, evidence and outcomes belong to the laboratory's own process.
Can a lifecycle review conclude that no action is needed?
Yes. The chart includes a continued-use route so a laboratory can document why the available information supports that conclusion. It also provides a separate route when a concern or improvement opportunity needs a defined action.
How does this differ from method change control?
Change control starts with a proposed modification and assesses its impact before implementation. Lifecycle review has a wider view of a method's status and evidence, and it may identify a change, a further assessment or a documented continued-use conclusion.
