<!-- section:swot -->
## SWOT Analysis {#swot}

**Core Strengths:**
- Multi-user account structure functions as a B2B distribution barrier into training centers

**Growth Levers:**
- Lack of active competition in the digital onsite guide space allows for a pivot to a modern, cloud-synced regulatory database


<!-- /section:swot -->
## Recent Changes (v2 → v3) {#recent-changes}

The assessment of GB Gas Onsite Guide has shifted from viewing the app as a stable legacy reference tool to identifying it as a professional liability. The primary change is the explicit recognition that the 2,121-day update gap renders the regulatory content dangerous for field use.

**Overall trend**: Declining
**Compared at**: 2026-08-23

### High-impact changes
- **[Shifted] Regulatory Liability Framing** (positioning)
- **[Added] Professional Safety Threat** (swot)
- **[Shifted] Sunset Recommendation** (positioning)

<!-- section:momentum -->
## App Momentum (Zombie) {#momentum}

<!-- section:so-what -->
## The "So What?" (Strategic Takeaway) {#so-what}

GB Gas Onsite Guide is a business app.

<!-- speakable-start -->
> **Bottom Line:** The 2121-day update gap invalidates the app's core value proposition as a regulatory guide, as static gas safety procedures are a liability for professional engineers.
<!-- speakable-end -->

**Best for:** Domestic natural gas engineers and trainees in the UK preparing for MLP or ACS assessments.

<!-- section:pm-actions -->
### PM Action Plan (Next Best Moves)

- [ ] [SUNSET] Sunset the platform because the 2121-day update gap renders the regulatory content obsolete and dangerous for professional use → prevent liability
<!-- /section:pm-actions -->

<!-- section:outlook -->
### Outlook: Declining

The market for professional regulatory tools demands high-frequency updates to maintain compliance with changing safety laws. GB Gas Onsite Guide is effectively a legacy product that cannot compete with current, cloud-updated alternatives, leading to inevitable user churn.

- 🔴 The 2121-day update gap indicates the platform is abandoned, which prevents it from reflecting current gas safety regulations and industry standards.
