Also, due to the high costs involved, MES applications were available only for manufacturers who could afford to make the effort. However, now there is a drastic transformation in the MES market space, where these systems are becoming more accessible to manufacturers irrespective of their industry segment or the amount of capital expenditure they can make.
Back in the day, MES applications were pretty much an on-site and tailor made IT system, which was made to model the current production process of the organization. This approach relied on traditional methodologies of software creation, which rendered the application largely inflexible, due to the design and architecture.
Since the approach for developing the application was rigid, any changes to be accommodated during the process of deployment would require fresh coding and thereby add further cost and effort. For small and medium scale manufacturers, the benefits offered by a large scale, tailor made application, were offset by the cost and effort factor. The smaller companies were often looking for only a part of the entire application, such as the SPC or maintenance management part, rather than the whole MES application. With the way the software was developed previously, this aspiration of deploying only a part of the application's functionality was still a far cry.
With the advent of better technologies such as cloud computing, better hardware & networking and better, more agile software development tools, such as Scrum, MES application vendors sensed the opportunity to offer their products as a more modular application, where customers could choose the exact module they wanted to deploy in their process and then scale the application as they start to reap the benefits.
The way in which modern MES applications have been able to transform from a large up-front investment to a pay as you go kind of deployment is truly fascinating.
