About

About Fragment Practice and its founder.

Fragment Practice is an independent advisory practice that turns ambiguous, complex issues into something an organization can decide and act on. Where AI, security, and technology risk meet, it separates the issues and produces the material for deciding, explaining, and handing off.

Founder Yasuhiro Shinsho started the practice in October 2025, after working on systems development and vulnerability assessment, IT risk and IT continuity, and security with cloud and AI risk assessment.

Practice overview

Clarifying decisions, responsibilities, and operating models even when the work is already under way.

In AI, security, and governance work, technical, operational, and management concerns arrive mixed together. Fragment Practice treats them as one connected question — what to promote, where control is needed, who decides, who reviews, and what to record — rather than as separate tool, compliance, or implementation tasks.

The work separates what needs deciding now, what can be carried forward as an established assumption, and what should be checked again when circumstances change, and frames each decision that is needed for the people responsible for making it. It starts from what can be operated with the roles and constraints already in place, and is laid out so it can be extended step by step.

Structured this way, the question becomes usable material: issue memos, decision material, role and operating design, review points, and handoff-ready next actions — written so the people who use them can keep them up to date after the work.

Founder profile

Yasuhiro Shinsho

Founder, Fragment Practice LLC

Yasuhiro Shinsho built and assessed systems at BIPROGY, consulted on IT risk and security at KPMG Consulting, and advised on security and cloud / AI risk at Nomura Research Institute / NRI Secure Technologies, then became independent in October 2025. The work moved from development and assessment, to structuring risk and control, to preparing what management and stakeholders need in order to decide.

He works between fast-moving AI capability and the slower, harder work of making it usable inside real organizations. Today that means the questions organizations stop at: whether customer information may be entered into a generative AI service, how far to go in meeting a security requirement a customer has asked for, who reviews a new external service and who is answerable once it is in use. Across AI governance, security governance, internal regulations, and technology risk, he breaks questions where several issues are tangled together down to a size the people involved can actually decide on, and turns them into decision material, review points, responsibility boundaries, and role / operating design.

The work done since becoming independent — governance for expanding generative AI use at a financial institution, and viability conditions for an AI-enabled security monitoring service at a systems integrator — is on Cases.

Who does what

Between the people who decide, operate, and build.

Fragment Practice clarifies issues, roles, review points, and responsibility boundaries, without taking on implementation or operations itself. The aim is to leave internal teams with less ambiguity about what to decide, how to explain it, where to review, and what to hand off.

Who does what

Clarifying the roles of deciding, operating, and building

Management decides acceptable risk, investment, and key policies; business and control functions design the operating conditions and reviews; internal teams or vendors design and build to those conditions. Fragment Practice prepares the decision material, review points, responsibility boundaries, and handoff conditions needed in between. Each holds a different responsibility; this is not a hierarchy.
