How effective and important is Lean/Six Sigma implementation in Human Resource area in today’s scenario?
"I am a fan of many of the principles and methodologies that Six Sigma & Lean promote, however, it is widely acknowledged that they are not always effective in dealing with "softer" aspects of certain disciplines, services or industries. They can be excellent tools for dealing in absolutes that involve metrics and processes, such as manufacturing and production, however, having had experience in these applications within a service industry (health & social care) they can often fall short when factoring in "soft" skills, such a perception, intuition, judgement and general gut feelings. For instance, a nurse or social worker can follow process, but can quite often be faced with a situation that requires them to override due process in favour of using their best judgement. An excellent, knowledgeable and insightful process facilitator (green/black belt) can factor these in when building and developing processes, but they can often be missed.
I prefer to "cherry pick" some of the robust and applicable components and principles of Six Sigma/Lean and apply them appropriately when building a bespoke process for a service-style working practice or function. I may be wrong here (as a non-subject matter expert in HR) but my perception of HR is that a portion of the working practices fall into what I call "vocational" applications, i.e the HR advisers use best judgment, perception and intuition when dealing with certain HR issues. Process methodologies would be fine in guiding an advisor on how to procedurally deal with a grievance or disciplinary situation, but allot of the actual undertaking will require soft skills and these cannot be factored into a process per se.
In summary, Six Sigma/Lean principles are fab at guiding a person through a critical path and ensure a high degree of efficiency and compliance (i.e. process milestones, such as updating/populating documentation, liaising with other parties or agencies and communicating at the right time) but they may not integrate core "soft " skills and factors that are required to complete the task. However, with good process development and management, these can be factored in to provide robust working practices for your HR Department." – Hayley Jaffrey Global Subsea QMS Leader at GE Oil & Gas
