AI Methodology and Framework
AI Methodology and Framework
Sigma’s AI methodologies combine industry research with our own best practices to guide organizations through AI adoption and continuous improvement
ARC: Align – Realize – Consolidate
Align
Before writing code, teams explicitly document architectural decisions, share understanding and identify design patterns. This step ensures everyone moves in the same direction.
Realize
Teams implement features with intention, applying architectural patterns and using AI tools with appropriate guardrails. AI amplifies patterns when intent is explicit and multiplies inconsistency when it’s implicit.
Consolidate
After implementation, teams validate the architecture, extract reusable patterns and prevent system drift. ARC complements Agile: Agile focuses on velocity and iteration; ARC ensures coherence and sustainability.
APEX: AI Program Execution Excellence
01
Assess
Evaluate current AI maturity—experimentation, pilot deployment, AI ways of working and readiness for scale—and identify gaps.
02
Plan
Set strategic objectives and choose AI technologies appropriate for each use case. Determine whether to use generative AI or traditional machine learning based on data availability, domain specificity and privacy concerns.
03
Execute
Launch pilots with clear metrics. Build AI‑native roles, train employees and embed AI into daily workflows.
04
Excel
Scale successful pilots across the organization. Invest in upskilling, impact measurement and change management to sustain improvements.
