Understanding the “wish list” for A&D contractors

Aerospace and defence companies all dream of the same improvements. But are they ignoring what can actually be done right now?

After nearly a decade as a mechanical engineer, I now spend my time working directly with some of the world’s largest aerospace and defense companies. What do I hear? The same three wishes. Every aerospace and defense company is chasing similar outcomes — perfect program execution, digital manufacturing agility and faster backlog conversion. The problem is achieving all three at once feels impossible. In this article, we’ll stack up the wishes against the realities and see how close we can get to closing the gap. First, let me play genie: A&D Contractors: “You are granted three wishes”

Wish 1: Flawless Program Execution

Let’s meet all of our deadlines

Defense contractors face significant challenges in managing cost overruns, missed schedules, and complex project requirements. A delay for a smaller company can run into the thousands of dollars. For A&D? Delays worth ten figures are at risk with every project.

For A&D? Delays worth ten figures are at risk with every project.

The first wish from the companies I regularly work with would be to achieve perfect program execution by delivering every program on time and on budget. The goals:

  • No unexpected cost escalations or schedule slip
  • Strong project governance, risk management, and accountability
  • Reliable transitions from design to production to delivery

Achieving this would free up capital, strengthen customer trust and improve profitability.

Wish 2: Advanced Digital Manufacturing and Supply Chain Agility

Increase efficiency and integration

Once you’ve got projects humming along, the next best step would be to improve the overall process. Right now one stalled supplier issue can bog down an entire build. With long development times, delays can snowball.  So the second wish would be to make a quantum leap in industrial-scale digital manufacturing. These organizations depend heavily on long, fragile supply chains and legacy systems that constrain output. If this wish came true, then companies could expect:

  • Fully digitalized, automated production lines (internally and externally)
  • Real-time integration between design, production and quality control
  • A supply network that’s resilient to disruptions and flexible in scaling

This transformation would boost throughput, reduce costs and support rapid delivery to customers.

Wish 3: Faster Backlog Conversion and Business Model Flexibility

Ship out orders faster by reducing production time

Wish 1 and 2 combine to support what we want to happen with No. 3. The third wish centers on converting massive backlogs into cash flow faster while diversifying revenue streams. Defense contractors often have years of committed orders tied up in production. The real challenge that I typically see is turning backlogs into predictable revenue. Let’s wish for:

  • Faster backlog-to-revenue conversion through operational efficiency
  • Stronger mix of recurring revenue
  • Modular, flexible contracts and scalable production

Achieving this would make revenue more predictable, cash flow more consistent and the business model more resilient to budget cycles.

Reality Check: What’s in Your Control?

Of course, no one gets three wishes. But every A&D company has real levers it can pull right now to make progress toward these goals. These five “inside-the-fence” levers determine how well a company executes, adapts and delivers. Every company I have worked with has the ability to execute the following and here’s how CoLab can help. The goal here is ultimately reducing capital allocation through faster production times.

Program Execution Discipline

What can be done now
  • Strengthen internal project management and accountability
  • Minimize design and manufacturing rework
How CoLab can help

CoLab removes the friction of getting manufacturing and quality eyes on designs early. Stakeholders can review CAD models, drawings and PDFs asynchronously, leaving in-context feedback that's easy to act on and that minimizes downstream rework. All discussions and decisions stay linked to the design itself, so that engineering teams can respond quickly.

Levers Workforce Capability
What can be done now
  • Train and develop high skill technical and digital talent
  • Increase collaboration and communication between stakeholders, especially suppliers and builders
  • Retain institutional knowledge across programs
How CoLab can help

CoLab strengthens workforce capability by giving engineers, manufacturing, and quality teams a shared environment to collaborate on designs. Teams can review CAD models, drawings and PDFs in one place, leave feedback directly on the geometry and tag others for input without waiting for meetings. Each comment and decision stays connected to the design, building a traceable record of context and rationale that helps new engineers learn faster and preserves the experience of senior staff across projects. This information accumulates: The software’s AI component can apply lessons learned from past reviews.

Enterprise Knowledge Management
Levers Internal Process Efficiency
What can be done now
  • Streamline design reviews, documentation and approvals
  • Implement lean manufacturing and agile engineering practices
  • Reduce bureaucracy and manual rework
How CoLab can help

Inefficient review and approval processes slow programs down long before production starts. With CoLab, A&D manufacturers can standardize how files move from upload to approval, ensuring every reviewer follows the same clear steps: upload → review → address feedback → record decisions. Feedback, markups, and decisions stay organized. This structure reduces rework, shortens review cycles, and builds lean, repeatable processes that scale across programs.

Levers Digital Transformation
What can be done now
  • Integrate digital tools across engineering, manufacturing and quality
  • Use data analytics to drive performance visibility
  • Adopt automation and digital twins internally
  • Introduce AI at the core of the business where it will be the most effective.
How CoLab can help

Digital transformation depends on connecting the tools and data already in use across engineering, manufacturing and quality. CoLab gives A&D manufacturers a shared review environment that integrates with existing CAD and PLM systems, so teams can inspect geometry, measure, and discuss designs without file conversions or manual transfers. Each review automatically captures structured feedback and decision data, creating a clear performance record that leaders can analyze to identify risks and bottlenecks. By turning day-to-day design reviews into reliable data sources, CoLab lays the groundwork for greater automation and digital twin initiatives. By adding AI to absorb and apply that knowledge, you’ve built a scalable system capable of evolving with you.

Levers Culture and Leadership Alignment
What can be done now
  • Drive accountability through metrics and incentives
  • Promote transparency and collaboration as core competencies
  • Communicate unified goals across business units
How CoLab can help

CoLab helps A&D manufacturers reinforce a culture of accountability and transparency by making design reviews measurable and visible across teams and programs. Every piece of feedback has a clear owner, status, and outcome, giving leaders real metrics to track follow-through. Because discussions and decisions are shared in one environment, teams can see how their work connects to broader program goals and learn from one another’s reasoning. This shared visibility strengthens collaboration across business units and builds a culture where accountability and communication are part of the daily workflow.

You don’t have a genie but you could have a modern, digital system and process

A&D clients have unique problems that require solutions made just for them. But having worked with several now, it’s obvious that just wishing won’t make solutions come true. You need someone who understands your sector requirements and knows how you function who can help make the changes you need happen. It’s the closest thing to a genie that you can actually get.
