Trustable Software Framework Consulting

Leverage the Trustable Software Framework (TSF) to enhance the safety, security, and reliability of your critical software systems.

Unlock the Potential of Your Critical Software with TSF Consulting

In today’s complex technological landscape, ensuring the trustability of software, especially in critical systems, is paramount. The Trustable Software Framework (TSF) offers a structured approach to manage and minimize risks associated with software development, integration, release, and maintenance. As a specialist in TSF, I provide expert consulting services to help your organization implement and benefit from this powerful framework.

What is the Trustable Software Framework (TSF)?

The Trustable Software Framework (TSF) is designed for software where aspects like safety, security, performance, availability, and reliability are critical. The core assertion of TSF is that any consideration of trust must be rooted in verifiable evidence.

The primary goal of TSF is to provide a structured argument for the trustability of a given software release. This is achieved by:

  • Gathering and presenting evidence across a range of factors known as Trustable Tenets and Trustable Assertions.
  • Calculating or estimating a confidence score for each Tenet and Assertion based on the available evidence.
  • Distilling these scores into an overall Trustable Score for the software release.

TSF acknowledges that complex software is unlikely to be bug-free or completely deterministic. Instead, it focuses on analyzing required behaviors in specific contexts, understanding what could go wrong, devising appropriate fixes or mitigations, and measuring confidence in these aspects.

Why Your Business Needs TSF Consulting

Implementing TSF can seem daunting, but the benefits for organizations dealing with critical software are substantial. Our consulting services can help you:

  • Manage and Minimize Risk: TSF provides a systematic way to measure, manage, and minimize the risks associated with each software release.
  • Enhance Software Quality: By focusing on evidence-based trust, TSF helps improve the overall safety, security, and reliability of your software.
  • Structured Approach to Critical Systems: Move beyond outdated practices and adopt a framework that is fit for purpose in the rapidly evolving software environment.
  • Improve Stakeholder Confidence: Demonstrate a clear, evidence-backed argument for the trustworthiness of your software to customers and regulatory bodies.
  • Address Complexity: TSF provides a model and methodology for reasoning about critical requirements and managing their interactions in a scalable manner, even for complex systems and those incorporating Free and Open Source Software (FOSS).
  • Achieve Compliance: Understand and work towards TSF compliance, signaling to users that sufficient information about the software’s properties is available for them to make informed trust decisions.
