iSAQB CPSA-Advanced Level FM (Formal Methods) introduces formal methods that supplement traditional software architecture practices by using mathematical techniques to specify and verify critical system properties.
Participants cover core topics such as logic, the link between specification and implementation, and how formal methods fit into the development process, supported by tools and practical examples. The course focuses on how to design architectures that are amenable to formal verification, including the implications for language and tooling choices when connecting specification and code.

Module 3: Formal Methods in the Development Lifecycle
Selection criteria for formal methods based on technical context and organizational needs.
Trade-offs between manual effort, expressiveness, and tool automation.
Strategies for the gradual introduction of formal methods into existing processes.
Using SMT/SAT solving and abstract interpretation to support architecture evaluation.
Module 4: Verification Tools and Techniques
Property-based testing to verify requirements with generated data.
Type systems and advanced typing concepts for static constraint checking.
Model checking to verify automata using temporal logic.
Proof assistants for deriving and verifying software system properties.
SMT solvers for checking constraints and mathematical proofs.
Abstract interpretation for predicting dynamic behavior, including pointer aliasing and data flow.
Module 5: Applied Examples
Practical application of formal methods to a specific system verification task or software architecture.
Certification & Exam
The iSAQB CPSA Advanced Level module FM (Formal Methods) is an accredited training module within the Certified Professional for Software Architecture, Advanced Level (CPSA-A) program.
Completing an FM course does not award a standalone “FM certificate”. Instead, it provides 30 credit points that count toward eligibility for the CPSA-A certification exam: 10 in Technical, 10 in Methodical, and 10 in Communicative competence.
To apply for CPSA-A certification, candidates must hold CPSA Foundation Level (CPSA-F), meet the experience prerequisites, and collect at least 70 credit points across at least three competence areas. The CPSA-A certification exam is based on an assignment, followed by assessment and an oral exam conducted by iSAQB-appointed experts.

What You Will Achieve
Course outcomes
Apply propositional logic, first-order (predicate) logic, and temporal logic operators to express system properties as precise formulas.
Analyze proof styles and logical calculi, including natural deduction, sequent calculus, and resolution, and distinguish classical from intuitionistic logic when selecting an appropriate reasoning approach.
Create formal specifications for functions, data types, algorithms, or whole systems, and differentiate between informal, formal, and mechanized specifications.
Design a refinement approach that links specification, intermediate models, and implementation, and assess when a separate model is needed between specification and code.
Evaluate where formal methods fit in the development process, and select suitable methods based on target qualities such as functionality, performance efficiency, security, or safety.
Conduct verification activities using selected tool families, including property-based testing, model checking, proof assistants, SMT solvers, and abstract interpretation, and interpret the results and their limitations.
Analyze type systems, including the role of dependent types, and assess how typing supports formal reasoning and verification of program properties.
Evaluate a software architecture with formal methods, using SMT or SAT solving for architectural constraint problems to support architecture evaluation and continuous refinement.
