Function analysis

Originating from TRIZ and Value Engineering, Function Analysis is a systematic methodology to deconstruct a system into its components and their interactions. It identifies the purpose (function) of each part, classifying them as useful or harmful. This approach is implicitly supported by standards like IEC 60812:2018 (FMEA) and EN 12973:2020 (Value Management), which are integral to risk management frameworks like ISO 31000. In trade secret protection, aligned with ISO 27001 asset management, it moves beyond simple asset lists. Instead of just listing 'a machine,' it identifies 'the function that provides a unique cooling cycle,' pinpointing the exact location of the core know-how. This precision allows for targeted, cost-effective security controls, distinguishing it from broader process mapping by focusing on the 'why' (purpose) and 'how' (interaction) rather than just the 'what' (sequence).

The practical application involves a structured, multi-step process. Step 1: System Decomposition. Define the system boundary (e.g., a manufacturing process) and break it down into its smallest physical or logical components. Step 2: Function Modeling. For each component, identify its function (e.g., 'transfers energy,' 'converts signal') and model the interactions. Step 3: Criticality and Risk Assessment. Analyze the model to identify functions that embody trade secrets. Tools like FMEA (IEC 60812) or TRIZ sabotage analysis are then used to identify potential leakage paths. For example, a Taiwanese semiconductor equipment manufacturer used this to protect a proprietary wafer-cleaning process. They identified the 'ultra-pure water cavitation control' function as the core secret. This led them to implement a non-replicable nozzle design and encrypt the control software, reducing reverse-engineering risk by an estimated 80% and ensuring compliance with their ISO 27001 controls.

Taiwan enterprises, particularly SMEs, face several key challenges. 1. Cultural Resistance: A reliance on empirical 'master-apprentice' knowledge transfer over structured, analytical methods. 2. Departmental Silos: Poor communication between R&D, manufacturing, and QA hinders the creation of a complete system model. 3. Resource Constraints: A reluctance to invest in specialized software and dedicate personnel time, viewing it as a non-essential cost. To overcome these, a phased approach is effective. Priority Action: Launch a pilot project on a high-value product, sponsored by senior management, to demonstrate tangible ROI within 3-6 months. Solution: Form a cross-functional task force guided by an external expert to establish standardized templates. Start with simple tools like mind maps before investing in complex software, and provide targeted, workshop-based training to build internal capabilities.
