Every Project Begins with Design
Your project’s success is determined in the design stage, so it’s crucial that you get it right. Especially for complex systems like aircraft, marine, and industrial systems, design needs to be done right the first time. As more and more companies are turning to model-based systems engineering (MBSE) to manage product development, it’s clear that they’ve made the same realization.
MBSE implements an architecture-based systems engineering approach which allows companies to manage project development, requirements, validation, and verification more effectively. But, these processes require expert intervention - which is where we come in.
Intertec’s team of experienced engineers and subject matter experts (SMEs) excel precisely in these areas. Intertec will provide you with expert guidance and support throughout the entire concept stage to create models, designs, and documentation that will eliminate disruptions.
Our system and guidance document expertise includes:
- Doors, Doors NG
- CAMEO, MagicDraw
- SysML
- ARP4754a
- MOSA, FACE
- Agile
Intertec will ensure that each and every component is tested and verified for optimal performance. With scalable engagement models, we will provide exactly the support you need, when you need it.
No matter how complex the project, Intertec will handle it - improving test accuracy, time-to-market, and scaling your team’s capacity.

- Seamless Integration: Mechanical, electrical, and software components are designed and developed in unison, preventing costly conflicts and ensuring everything works together perfectly from day one.
- Faster Time-to-Market: With streamlined communication and fewer handoffs between separate vendors, design cycles are accelerated, issues are detected earlier, and your product gets to market faster.
- Enhanced Quality & Reliability: A unified vision and comprehensive testing across all disciplines lead to a more robust, reliable, and higher-performing final product.
- Reduced Costs & Risks: Early problem detection, minimized rework, and optimized resource allocation translate directly into significant cost savings and more predictable project outcomes throughout the product lifecycle.
- Unified Oversight: Strong systems engineering ensures all requirements are met and risks are managed proactively, providing full traceability and confidence in complex projects.
Component & Systems Testing
Improve Time to Market and Increase Capacity
Every component, system, and subsystem that goes into something as complex as a turbine engine must be exhaustively vetted and tested for both safety and regulatory compliance. Often, these requirements compromise time-to-market and stretch the capacity of already overloaded systems.
But - it doesn’t have to be that way.
With Intertec, you can obtain expert component certification and validation, on-time and on-budget. To keep your project running smoothly and safely, we ensure requirements flow validation and conformity inspections, in addition to compliance in:
