Job Description Series, Part 5: Define What Success Looks Like
Each success signal should follow a pattern: Outcome → Evidence → Impact
TJ Kastning
The best leaders know that people cannot hit a target they cannot see. Yet most job descriptions never tell candidates or employees what “winning” in the role looks like.
Instead, they stop at activities and vague traits. “Manage the schedule.” “Be detail-oriented.” That does not give anyone a scoreboard. Without a clear picture of success, even high performers may feel like they are failing, or worse, assume they are succeeding when they are not.
Why Defining Success Matters
- Clarity: Candidates know exactly what is expected if they take the role.
- Accountability: Leaders can fairly measure contribution instead of guessing at effort.
- Motivation: People thrive when they can see progress toward meaningful goals.
The 30 / 90 / 365 Framework
A practical way to define success is by looking at milestones:
- First 30 Days: What foundational wins must be in place? (Example: relationships built, systems learned, processes understood.)
- First 90 Days: What measurable contributions should be visible? (Example: accurate project reports delivered, client trust established, team direction clear.)
- First 365 Days: What long-term impact should be undeniable? (Example: projects completed profitably, safety record maintained, repeat business secured.)
How to Write Success Statements
Each success signal should follow a pattern:
Outcome → Evidence → Impact
Example:
- Outcome: “Project schedules are consistently reliable.”
- Evidence: “Milestones tracked with fewer than two missed deadlines in the first year.”
- Impact: “Client confidence and repeat business are protected.”
The Candidate Effect
When candidates see a job description that spells out success, they can answer the most important question in any career move: Can I win here?
Those who cannot picture themselves succeeding will filter out. Those who can will come in more focused, motivated, and aligned.
The Takeaway
Defining success is not extra, it is essential. A job description without a scoreboard leaves everyone guessing. A job description with clear 30, 90, and 365-day outcomes turns uncertainty into alignment, and alignment into performance.
