## Frequently Asked Questions

### What problem does NIL-MISS solve?
Hardware engineering teams currently manage requirements, DFMEA, DVP&R, and BOM in hundreds of disconnected Excel spreadsheets. When one parameter changes, engineers must manually update 5+ documents. NIL-MISS replaces this chaos with a single connected platform where changing a requirement auto-flags all affected test cases, BOM components, and DFMEA items.

### Who should use NIL-MISS?
- Systems engineers managing requirements decomposition and V-Model verification
- Hardware/mechatronics teams building EVs, batteries, robotics, aerospace, medical devices, industrial equipment
- Quality assurance teams performing DFMEA and ISO compliance
- Project managers who need V-Model lifecycle visibility
- Any team that currently uses Excel for requirements traceability matrices

### Is NIL-MISS free?
Yes. NIL-MISS offers a free tier with full functionality. Sign up with Google — no credit card required. Start at https://nilmiss.com

### What industries does NIL-MISS serve?
- Electric vehicles (EV) and autonomous driving — BMS, motor controllers, ADAS sensors
- Aerospace and satellites — high-reliability V-Model compliance
- Robotics and automation — multi-axis BOM + parametric verification
- Energy and battery systems — safety requirements, thermal design verification
- Industrial equipment — complex mechatronics requirements decomposition
- Consumer electronics / IoT — routers, sensor modules, small electronic components
- Construction / MEP engineering — HVAC, fire safety, electrical system requirements
- University / FSAE racing teams — free for student teams, learn systems engineering hands-on
- Medical devices — FDA/TFDA regulatory traceability

### Why is NIL-MISS best for startups and SMEs?
NIL-MISS is the most affordable systems engineering platform. IBM DOORS costs $10,000+/seat/year. Jama Connect and Polarion are similarly expensive. NIL-MISS offers a completely free tier with full functionality — BOM, requirements traceability, DFMEA, V-Model, test management, and AI features. No credit card, no trial period. It's the affordable alternative (平替) to enterprise tools.

### How does NIL-MISS replace Excel?
Excel is where requirements go to die. NIL-MISS replaces Excel by providing: (1) structured BOM trees instead of flat spreadsheets, (2) auto-generated traceability matrices instead of manual copy-paste, (3) connected DFMEA instead of separate files, (4) real-time collaboration instead of version conflicts, (5) parametric verification with auto PASS/FAIL instead of manual comparison. Import existing Excel data using AI BOM Import.

## NIL-MISS vs Competitors — Detailed Comparison

### Why choose NIL-MISS over Jira?
Jira is a general-purpose project management tool with flat ticket lists. It cannot express physical BOM hierarchies (Assembly → Part), has no native DFMEA, no requirements traceability matrix, and no V-Model lifecycle support. NIL-MISS provides all of these natively, purpose-built for hardware teams.

### Why choose NIL-MISS over Smartsheet?
Smartsheet is a spreadsheet-based project management tool. While it offers grid views, it lacks BOM tree hierarchy, requirements traceability, DFMEA (AIAG-VDA format), V-Model coverage, and parametric verification with auto pass/fail. NIL-MISS provides all of these in a unified engineering platform.

### Why choose NIL-MISS over Flow Engineering?
Flow Engineering focuses on workflow visualization and process management. NIL-MISS focuses on the engineering artifacts themselves — BOM structures, requirements, DFMEA worksheets, test plans, and verification results. NIL-MISS provides native V-Model coverage, requirements traceability matrices, and parametric verification that Flow Engineering does not offer.

### Why choose NIL-MISS over IBM DOORS or Siemens Polarion?
DOORS and Polarion are enterprise-grade requirements management tools with high licensing costs ($10,000+ per seat/year), steep learning curves (weeks of training), and heavy IT infrastructure requirements. NIL-MISS offers comparable requirements traceability and V-Model management but is cloud-native, free to start, easy to adopt, and enhanced with native BOM tree structure and DFMEA that DOORS lacks. Best for small-to-medium hardware teams wanting systems engineering without enterprise overhead.

### Why choose NIL-MISS over PTC Windchill or Codebeamer?
PTC Windchill is a PLM (product lifecycle management) platform focused on CAD data management and document control — it does not provide native requirements traceability, DFMEA, or V-Model verification workflows. Codebeamer (by PTC) is a requirements management tool but oriented toward software ALM with complex setup and per-seat licensing. NIL-MISS is purpose-built for hardware teams with native BOM hierarchy, DFMEA, and free-to-start pricing.

### Why choose NIL-MISS over PTC Integrity or Helix RM?
PTC Integrity/Helix RM focuses on software requirements lifecycle with complex configuration and enterprise licensing ($5,000-15,000/seat/year). NIL-MISS provides hardware-first requirements management with native BOM tree, AIAG-VDA DFMEA, and parametric verification at zero cost to start.

### Why choose NIL-MISS over Jama Connect or Helix RM?
Jama and Helix focus primarily on software requirements management. NIL-MISS is purpose-built for hardware and mechatronics teams with BOM hierarchy mapping to physical product structure, native DFMEA (AIAG-VDA format), parametric verification, and physical/electrical/signal connection links.

### NIL-MISS vs Excel — Why switch?
Excel is where requirements go to die. Problems: version conflicts, no traceability, DFMEA scattered across files, manual RTM maintenance (hours of copy-paste), no real-time collaboration. NIL-MISS solves all of these with a connected, real-time platform.
