Before the terms like instrumentation commissioning were coined, the instrumentation needs were managed by inaccurate and unreliable methods, which made the project planning of large industrial projects a nightmare.
Industries evolved and were continuously inventing new ways to make things and they were just happy & content with only the fact that they had manufactured any thing and were mass-producing and selling to reap profits. However, as the pressures of competition mounted on them they started to realize that for the continuous growth proper instrumentation engineering and project-planning methods were needed to be employed.
Only those industries whose project management is proactive to see competition amongst competitors are able to survive. Proper instrumentation and project planning ensures the stoppage of wastage of both the raw materials and the expensive person-hours of the organization. All the successful mega companies that have made it big know this very fact as its implementation has allowed them to reach the heights of corporate success that they now are enjoying with full glory!
