What is Tech Stack Assessment?
A tech stack assessment evaluates every tool, platform, and system your business relies on across 8 critical dimensions: infrastructure reliability, security posture, scalability readiness, integration quality, cost efficiency, team skills coverage, documentation maturity, and redundancy planning. It identifies hidden risks like key-person dependency, wasted SaaS spend, and single points of failure that could take your business offline.
The Formula
Tech Stack Score = Sum of category scores (0-10 per question, 10 questions) SaaS Waste Rate = (Unused Licences + Overlapping Tools) ÷ Total SaaS Spend × 100 Key-Person Risk = Number of systems only one person can maintain
Each question scores 0, 3, 7, or 10 based on maturity level. The total score benchmarks your stack against industry averages.
Worked Example
A 30-person SaaS company uses 45 tools across engineering, marketing, sales, and operations. Monthly SaaS spend is £12,000. One senior developer manages all infrastructure.
- Infrastructure: Managed cloud with CI/CD but no disaster recovery (7/10)
- Security: SSL and patching but no penetration testing or SOC 2 (3/10)
- Scalability: Can handle 3x growth with manual intervention (3/10)
- Integration: API connections between core systems, some manual steps (7/10)
- Cost Efficiency: Know total cost but 8 unused licences identified (3/10)
- Team Skills: One person manages infrastructure, no cross-training (0/10)
- Documentation: Architecture documented but outdated (3/10)
- Redundancy: Database backups exist but never tested (3/10)
- Tool evaluation: Informal process, some ad hoc adoption (3/10)
- Tech debt: Aware but no dedicated capacity (3/10)
📌 Total score: 35/100 — below the SaaS average of 44. Critical gaps in security (no penetration testing), key-person dependency (one infrastructure engineer), and untested backups. Immediate priorities: cross-train a second engineer on infrastructure, test backup recovery, and eliminate 8 unused SaaS licences to save £1,400/month.
Why This Matters
Cost reduction
The average company wastes 20-30% of SaaS spend on unused licences, duplicate tools, and shelfware. A quarterly audit typically saves £2,000-£10,000 per year for a 30-person team.
Risk mitigation
Single points of failure — one server, one database, one engineer who knows the system — are existential risks. A tech stack assessment identifies these before they cause downtime or data loss.
Scalability readiness
Growth breaks fragile stacks. Companies that proactively assess scalability avoid the costly "we need to rebuild everything" moment that derails product development for months.
Common Mistakes
❌ Evaluating tools in isolation
Individual tools may be excellent but the stack as a whole may have integration gaps, redundancies, or security holes. Assess the system, not just the components.
❌ Ignoring key-person dependency
If one engineer leaving would cripple your infrastructure, you have a critical business risk. Cross-training and documentation are cheaper than an outage.
❌ Never testing backups
Backups that have never been tested are not backups. Regularly perform recovery drills to ensure you can actually restore systems within your target recovery time.
Industry Benchmarks
| Category | Good | Average | Poor |
|---|---|---|---|
| SaaS Waste Rate | Below 10% | 20-30% | Above 35% |
| Mean Time to Recovery | Under 1 hour | 1-4 hours | Above 8 hours |
| Documentation Coverage | Above 80% | 40-60% | Below 25% |

From working with SaaS founders, the ones who embed a metrics calculator on their investor or pricing page consistently report shorter sales cycles — prospects arrive at the call already knowing their numbers.
One of the most common mistakes we see when working with clients: evaluating tools in isolation. Individual tools may be excellent but the stack as a whole may have integration gaps, redundancies, or security holes. Assess the system, not just the components.
