In my article Project Manager vs Product Manager vs Product Owner vs Scrum Master, I argue that communication and the critical path are more vital to project success than the roles themselves. Regardless of how roles are distributed or merged, what truly matters is clarity—clarity in who is responsible, who is accountable, and how each task contributes to timely, on-budget delivery.
In a software maintenance project, where roles are often collapsed due to budget constraints, the key is to anchor accountability to activities, not titles. Here's how you can apply your context—lean teams, role synergy, and cause-effect awareness—to make maintenance projects robust and defensible:
Role Compression with Accountability
In most maintenance setups, you won’t have the luxury of one person per role. Instead, someone—often you—will wear multiple hats. You might be the Product Owner, Project Manager, and Scrum Master all at once. That’s not ideal, but it’s common.
You might have one person acting as:
- Product Manager + Product Owner: owning the backlog, prioritizing fixes, and aligning with business needs.
- Project Manager + Scrum Master: planning releases, tracking progress, facilitating stand-ups, and managing risks.
The key is this: roles can collapse, but activities must not. You should map key activities—not just roles—and ensure each has a clear owner. Use a RACI chart or overlay to define who is Responsible, Accountable, Consulted, and Informed for:
- Incident triage
- Bug prioritization
- Release planning
- Stakeholder updates
- Documentation updates
- SLA compliance
Kanban: A Fit for Maintenance
Kanban is well-suited for maintenance because it:
- Embraces continuous flow
- Prioritizes visibility
- Avoids artificial time-boxing
- Supports dynamic prioritization
But Kanban doesn’t eliminate the need for planning. It just shifts the focus from sprints to flow. And within that flow, critical path awareness still matters.
Critical Path in Maintenance
Even in maintenance, there’s a critical path—especially for:
- Security patches
- Regulatory fixes
- Customer-impacting bugs
These items form a floating critical path—a set of tasks that, if delayed, cause real-world consequences. You must:
- Identify these tasks early
- Track dependencies (e.g., waiting on infrastructure or vendor input)
- Communicate risks (e.g., “This patch must go live before X date or we breach Y compliance”)
- Re-plan when scope or urgency shifts (e.g., new feature request bundled into a hotfix)
Cause and Effect in Maintenance
Maintenance is a live environment. Every change has ripple effects. For example:
- Customer reports a bug (cause) → triggers triage, prioritization, and possibly a hotfix (effect)
- New feature request (cause) → may introduce risk or require reallocation of resources (effect)
- Missed patch window (cause) → you escalate and revise release plan (effect)
- A delayed infrastructure update (cause) → impacts release timing and customer SLAs (effect)
Documenting these chains helps defend decisions and clarify trade-offs. As a Project Manager (or the person acting as one), your job is to identify these chains and communicate their impact.
Collaboration in Lean Teams
Even if you’re the only one wearing multiple hats, build lightweight rituals to simulate role separation:
- Weekly triage meetings (Product Owner hat)
- Monthly stakeholder syncs (Product Manager hat)
- Release planning sessions (Project Manager hat)
- Daily stand-ups or async updates (Scrum Master hat)
Use templates and automation to reduce overhead—e.g., auto-generated status reports, shared dashboards, and email digests.
| Activity | Role Simulated | Frequency |
|---|---|---|
| Weekly triage | Product Owner | Weekly |
| Stakeholder sync | Product Manager | Monthly |
| Release planning | Project Manager | As needed |
| Daily stand-up or async update | Scrum Master | Daily or async |
Final Thought
In maintenance projects, success doesn’t come from perfect role alignment. It comes from clarity of ownership, awareness of impact, and consistent communication. If something goes wrong, someone will ask, “Who was responsible?” Make sure you can answer that with confidence.
