Value stream analysis for complex processes and systems

Understanding the current condition of complex systems and systematically improving is a difficult challenge, which many organizations are struggling with. Repeatable success requires the right method in addition to domain expertise. Lean value stream mapping (VSM) is a commonly used method that has been applied successfully in many domains. Despite its success VSM does have short comings when it is used to analyse complex processes where the value produced varies for different stakeholders and is largely intangible. Traditional VSM also lacks a practical way of modelling elements that are present in multiple steps of the value stream and a systematic approach to generating different type of improvement ideas (incremental and step change). This article introduces a value stream analyses method for complex systems, which combines traditional value stream mapping with TRIZ analyses (Ideality, functional world, FAA, perception mapping) and ideation tools (trimming, inventive principles, inventive provocations). The new method is designed to solve the weaknesses of VSM and enable systematic idea generation based on a holistic understanding of the system (including intangible perspectives). The method also integrates practical facilitation practices to ease the learning curve for participants. The article will also present two case studies from an IT company (change management and financial reporting and forecasting processes) and analyse results and benefits of the new hybrid method.
