Fix the root cause, not the symptom.

5-Why analysis, Pareto charts, and corrective action tracking. Solve problems permanently. Stop the same issues from coming back.

5-Why Analysis
1
Micro-pitting on panels? Bath acid concentration too high.
2
Concentration high? Dosing pump recalibrated incorrectly.
3
Incorrect calibration? Maintenance used outdated procedure.
4
Outdated procedure? Document update not distributed.
5
Not distributed? No automated revision notification.
Root Cause
Maintenance procedure revision not distributed to technicians after process update
Corrective Action
Implement automated document distribution with mandatory read-receipt for all process-critical procedures
Preventive Action
Deploy revision control system with automated notification and acknowledgment tracking for all maintenance SOPs.

The same problems kept returning

You fixed it last month. And the month before that. The corrective action was "retrain the operator" and everyone moved on. But the problem came back, because nobody dug deep enough to find the real cause.

Now problems stay solved

TeamGuru's structured 5-Why workflows guide teams past surface-level answers to genuine root causes. Every root cause generates corrective and preventive actions with mandatory effectiveness verification. When verification confirms it worked, the problem is closed for good.

What you get

Structured 5-Why analysis

Guided workflows walk teams through each "why" with branching support for multiple cause chains. The system prevents premature conclusions.

Pareto prioritization

Automatically generated Pareto charts show which problem categories contribute most to quality issues, helping teams focus their limited resources where it matters.

Corrective and preventive actions

Every root cause generates both corrective actions (fix this instance) and preventive actions (prevent recurrence). Both are tracked to completion.

Effectiveness verification

After corrective actions are implemented, the system prompts for effectiveness verification to confirm the problem is actually solved.

Everything connects.

Root Cause & Actions works on its own. Connected to the rest of TeamGuru it does more: every module below runs on the same platform, with one login.

Root Cause & Actions

Quality Alerts

Quality incidents trigger RCCA workflows automatically with full problem context carried over.

Projects & Actions

Corrective actions flow into the central action system with full traceability to the original problem.

KPI Dashboards

Track RCCA completion rates, time to root cause, and recurrence rates on quality dashboards.

8D Problem Solving

Root cause analysis feeds directly into the 8D report structure for customer-facing responses.

Common questions

Is the 5-Why analysis configurable? +
Yes. You can configure the minimum and maximum number of "why" levels, require evidence at each level, and enable branching for problems with multiple contributing causes.
Can we use Ishikawa (fishbone) diagrams? +
Yes. The fishbone is one of the analysis tools inside RCCA: you fill it in there, next to 5-Why and Pareto, and the causes it surfaces become corrective actions with an owner and a date.
How do we ensure corrective actions are actually effective? +
The module includes a mandatory effectiveness verification step. After the corrective action is implemented and a monitoring period passes, the system prompts the owner to confirm the problem has not recurred.
Can we link multiple incidents to the same root cause? +
Yes. When a new incident has the same root cause as a previous one, you can link them together. This also surfaces when a supposedly "solved" problem keeps recurring.
Who can initiate a root cause analysis? +
Any team member can initiate an RCCA. You can also configure automatic triggers from quality alerts, customer complaints, or KPI threshold breaches.
