SBI Feedback Model - Complete Guide
The Situation-Behavior-Impact (SBI) model, developed by the Center for Creative Leadership, provides a structured approach to giving clear, objective feedback that minimizes defensiveness and promotes improvement.
The SBI Formula
Situation + Behavior + Impact = Effective Feedback| Component | What It Is | What It's NOT |
|---|---|---|
| Situation | When and where the behavior occurred | Vague timing or generalizations |
| Behavior | Observable actions the person took | Assumptions about motives or character |
| Impact | Effect on you, the team, or the project | Judgment or evaluation |
Why SBI Works
- Specificity - Concrete examples are harder to dismiss than vague complaints
- Objectivity - Observable behaviors can't be argued; interpretations can
- Actionability - Clear situations and behaviors can be repeated or changed
- Non-threatening - Impact focuses on effects, not character attacks
SBI Examples: Positive Feedback
Code Review Excellence
Situation: "In the code review for the payment processing module last Tuesday..."
Behavior: "...you not only caught the edge case that would have caused data loss, but you also suggested a more elegant solution using the repository pattern and included tests that demonstrated the issue..."
Impact: "...which prevented a potentially costly bug in production and taught our junior developers about defensive coding. The whole team learned from your thoroughness."
Meeting Contribution
Situation: "During our architecture decision meeting this morning..."
Behavior: "...you asked three questions that reframed the problem and suggested we document our trade-offs in an ADR..."
Impact: "...which helped us reach consensus in half the usual time and gave us documentation we can reference later."
Mentorship
Situation: "Over the past month while onboarding Maya..."
Behavior: "...you've been setting up daily 15-minute check-ins, creating a shared doc of resources, and giving her progressively more complex tasks..."
Impact: "...which has accelerated her ramp-up significantly. She submitted her first independent PR two weeks ahead of our typical onboarding timeline."
Cross-Team Collaboration
Situation: "When the DevOps team asked for help migrating the deployment pipeline last week..."
Behavior: "...you volunteered to pair with their engineer, documented the process as you went, and stayed late to ensure the cutover succeeded..."
Impact: "...which built goodwill between our teams and created documentation that will help us next time."
SBI Examples: Constructive Feedback
Missed Deadlines
Situation: "This sprint, the API endpoint work was due on Wednesday..."
Behavior: "...it was delivered on Friday without any communication about the delay..."
Impact: "...which blocked the frontend team for two days, caused them to miss their milestone, and created tension between our teams."
Follow-up prompt: "What happened? Is there something blocking you that I should know about?"
Code Quality Issues
Situation: "In the last three PRs you submitted..."
Behavior: "...there were no unit tests and several of the changes broke existing tests that weren't updated..."
Impact: "...which caused the CI pipeline to fail repeatedly, blocked other developers' merges, and required the tech lead to spend time debugging."
Follow-up prompt: "I want to understand what's making testing difficult. Is there something about our test setup or your workload that's contributing to this?"
Meeting Behavior
Situation: "In yesterday's standup..."
Behavior: "...when Alex was describing their blocker, you interrupted three times to offer solutions before they finished explaining..."
Impact: "...which made Alex visibly frustrated and may have prevented them from sharing the full context of the problem."
Follow-up prompt: "I know you're eager to help, and that's great. Can we try letting people finish before jumping in?"
Communication Gaps
Situation: "When the production issue happened on Monday..."
Behavior: "...you started investigating immediately but didn't post updates in the incident channel for 45 minutes..."
Impact: "...which left leadership and customer support without information to share with affected clients, and caused multiple people to ask for status updates, further distracting you."
Follow-up prompt: "During incidents, even brief updates help. What would make it easier to communicate while you're troubleshooting?"
Lack of Engagement
Situation: "In our last three sprint planning sessions..."
Behavior: "...you haven't provided estimates or raised concerns about any of the stories..."
Impact: "...which means we're missing your technical perspective, and some stories have turned out to be much larger than expected."
Follow-up prompt: "Your input is valuable. Is there something about our planning process that's making it hard to participate?"
Common Mistakes to Avoid
Mistake 1: Vague Situation
❌ "Recently..." ❌ "In general..." ❌ "Sometimes..."
✅ "In yesterday's standup..." ✅ "During the deployment on March 15th..." ✅ "In the code review for PR #1234..."
Mistake 2: Interpreting Instead of Observing
❌ "You don't care about quality" (interpretation) ✅ "The PR had 12 bugs caught in QA" (observable)
❌ "You're not engaged" (interpretation) ✅ "You were on your phone during the demo" (observable)
❌ "You're being defensive" (interpretation) ✅ "You raised your voice and said 'that's not my fault'" (observable)
Mistake 3: Generalizing Behavior
❌ "You always miss deadlines" (generalization) ✅ "The last three deliverables were past their due date" (specific)
❌ "You never test your code" (generalization) ✅ "The last two PRs had no unit tests" (specific)
Mistake 4: Making Impact Personal
❌ "...which made me angry" (personal feeling as impact) ✅ "...which caused the release to be delayed" (business impact)
Personal feelings can be part of impact, but should be secondary to business/team impact: "...which delayed the release and, honestly, created frustration for the team."
Mistake 5: Forgetting the "So What"
Feedback needs clear impact to be meaningful. Without it:
❌ "In the meeting, you interrupted Alex three times." (So what?)
✅ "In the meeting, you interrupted Alex three times, which prevented them from fully explaining the problem and may have led to us missing important context."
Extended SBI: Adding Intent and Next Steps
Some practitioners extend SBI to SBI-I (adding Intent) or SBI-NS (adding Next Steps):
SBI-I: Checking Intent
After delivering SBI feedback, ask about intent:
SBI: "When you pushed to main without a PR yesterday, it broke the build and blocked five developers for two hours."
I (Intent): "I'm sure you didn't mean to cause a disruption. Can you help me understand what happened?"
SBI-NS: Proposing Next Steps
End with a collaborative discussion of what to do differently:
SBI: "When you gave estimates without checking with the backend team, the sprint became overcommitted and we had to drop two stories."
NS: "Going forward, could we establish a quick sync with backend before finalizing sprint commitments? What would make that work for you?"
When to Use SBI
| Scenario | Use SBI? | Notes |
|---|---|---|
| Formal performance feedback | ✅ Yes | SBI provides documentation |
| Quick in-the-moment feedback | ✅ Yes | Keep it brief but structured |
| Positive recognition | ✅ Yes | Makes praise specific and meaningful |
| Annual reviews | ✅ Yes | Have multiple examples ready |
| Giving yourself feedback | ✅ Yes | Use for self-reflection |
| Venting frustration | ❌ No | Get calm first, then use SBI |
Practice Exercise
Take a recent situation where you wanted to give feedback. Fill in:
Situation: ________________________________________________
Behavior: ________________________________________________
Impact: ________________________________________________
Now check:
- Is the situation specific (time/place)?
- Is the behavior observable (not an interpretation)?
- Is the impact clear (business/team effect)?
