This document discusses the importance of applying a system life cycle approach to industrial control systems. It recommends following six key stages: planning, analysis, design, construction, testing, and rollout. Additionally, it advocates learning from other industries like chemicals and pharmaceuticals that take a rigorous requirements-based approach to systems by defining needs upfront and ensuring equipment meets specifications before design and implementation.

2.  Traditional software systems have
requirements definitions and planning with a
system life cycle implementation.
 So should industrial controls.

3.  6 stages
◦ Planning
◦ Analysis
◦ Design
◦ Construction
◦ Test
◦ Rollout
(Morris, 2013).

5.  Due Diligence with Requirements
◦ System purpose
◦ System life cycle
◦ System fault criteria
◦ System interface criteria
◦ Hardware criteria
◦ Deliverables
◦ Time frame
◦ Training

6.  Everyone should learn from the chemical and
pharmaceutical industry
◦ Don’t accept equipment that does not meet
prescribed requirements
◦ Make sure your requirements are in place before
allowing design functions to start
◦ Decrease maintenance and poor start ups
◦ Make fault predictions early on
