Why it matters

WCCA isn't just a box to check off. It's an integral part of a robust design process — helping you uncover potential weaknesses early, reduce redesign cycles, and protect against downstream failures that could compromise safety, performance, or schedules.

When performed during the design phase, WCCA provides the clarity needed to make informed trade-offs, verify margin, and prevent issues that might otherwise surface only during qualification testing or, worse, in the field.

Our approach

You're out of time and resources. Deadlines are closing in. Critical design reviews are approaching.

You need fast, accurate analysis — done with approved methods and integrated seamlessly into your design and documentation. You need issues identified and resolved quickly.

You need a partner who understands what your customer expects from a WCCA — with the tools, models, and experience to get it right the first time. A guide who can navigate the challenges, ease the process, and bring credibility to your project.

Meeting schedule, budget, and technical goals. That's what AEi Systems delivers — unlike any in-house team or consultant.

Questions to Consider

Before deciding whether a WCCA is appropriate for your program, consider:

• How much design risk can your project tolerate?
• What would a failure mean — financially, operationally, or reputationally?
• What is the heritage and complexity of the circuitry involved?
• What are the relative costs of performing vs. not performing a WCCA?

Benefits of a WCCA

A properly executed WCCA provides measurable engineering and business value:

• Validates performance across all expected conditions (Worst Case Extreme Value Analysis)
• Defines critical components and Specification Control Drawing (SCD) limits
• Establishes Acceptance Test Procedure (ATP) limits
• Determines the need and range for Select-at-Test (SAT) components
• Improves reliability through parts stress and derating analysis
• Identifies potential failure points before they cause damage or degradation
