Lungile Binza, CIO, South African Mint Company Ltd

Gauteng, South Africa − Struggling with a manufacturing information management system that was installed in 1992 and last updated in 2000, SA Mint decided that it was time for a radical upgrade that would involve the latest MES and EMI technologies and approaches commensurate with the company’s product excellence and world-wide reputation.

The manufacturing process at SA Mint is characterised by a need for efficiency, security and tight production accounting – not to mention consistent product quality and dependable automation. The company bears a unique responsibility for delivering high quality products consistently, on time and in large volumes. This is an environment that has little or no tolerance for unreliable performance or lack of control and which has to meet the budget constraints of 21st century economics.

The production process is quite complex and has a large number of steps that must be followed precisely to make a single coin but, although this was already being handled, the real problem lay with management information – there wasn’t any. This meant that business continuity management couldn’t be guaranteed and reporting was a tedious business which was seldom on time to be effective.

Other concerns were that the existing solution couldn’t be integrated with others, depended on only one person for support and was based on very old operating and database management systems as well as an ancient technology infrastructure that was no longer supported.

“In 2005, a decision was made to completely overhaul and enhance our factory systems,” says Lungile Binza, CIO at the South African Mint Company Ltd. “This was the start of project Pelo – a Sesotho word for “heart” as this would be the heart of our operations. The plant needed a system that would provide material traceability, ensure data integrity and provide a solution that is flexible enough to accommodate changes in our manufacturing environment. The system would also have to assist with inventory optimisation by providing information about the availability and location of inventory items. We were looking forward to far greater visibility into our KPIs while the system facilitated production flow without compromising control or security at the same time as providing real-time production information including OEE.”

In 2010/1, after a false start, project Pelo was put back on track based on SA Mint’s business needs rather than the process requirements. “At the time of this restart, the MES workflow technology was brand new and there were no referral sites in South Africa. We knew that we couldn’t tolerate anything going wrong and adopting this technology was initially considered too risky and the proposals were rejected. We were not going to have a ‘guinea-pig experience’,” continues Binza. “But a top-level presentation by Wonderware Southern Africa (now IS³) showed us their commitment to a future where model-driven MES and workflow management would become the norm because that’s what customers wanted. This new paradigm would be introduced and supported, and training would be provided just as had happened with the rest of AVEVA’s product range, supplied by IS³. In fact, because of the needed human interaction and decision-making at the MES level, it soon became apparent that the integration of workflows would become the norm rather than the exception. Even so, the board of SA Mint insisted on introducing a system of checks and balances – but more about that later.”

The implementation of AVEVA MES in our factory made our lives easier and saved us much needed time. With its friendly user interface, we are able to access factory performance information in real-time.”

In 2012, Pelo phase 3 was started and the first step was to address the needs of the Plating Area whose business objectives included:

  • Allowing the business to schedule any denomination through the plating area at any time
  • Assisting the production team with the on-time delivery of products through planning methodologies such as theory of constraints (ToC) and lean manufacturing practices.
  • Manufacturing good-quality products.
  • Providing production management, the information to reduce manufacturing costs.
  • Replacing the current factory and material handling systems
    Interfacing with other systems such as the ERP and material handling systems
  • Next in line were the Plating Area’s operational requirements:
  • Promoting the flow of material through in-line processing,
  • Improving the traceability of the material by ensuring that, in case of a breakdown of the upstream equipment, there is off-loading capacity of the work in process at both the QA stations and the furnace exit. This provision will be made by having off-loading bins which are permanently in line
  • Eliminating storing material on the shop floor
  • Minimising manual movement of the material in and out of the line and across the plating lines (i.e. furnace and polishing).
  • Creating customer value and continually reducing waste
  • Embedding 5S principles and improving housekeeping


SA Mint selected system integrator Systems Anywhere Coastal to assist with the implementation because of the company’s track record of successfully supplying multi-level decision-support solutions to many companies in the mining and manufacturing industries.

“We needed to track production, downtimes, shifts and running times as well as monitor the status of machine and production weights,” says Paut Kotze, Software Engineer at Systems Anywhere Coastal. “All development had to comply with SA Mint’s standards and quality criteria and this was especially important in the case of validating manual entries through the 14 InTouch HMI stations. These display production input, output and stoppages in real time. We also developed our own security features for linking to other systems.”

AVEVA’s System Platform, host to all applications including the model-driven MES and business intelligence solutions, provided easier system maintenance and the management of standards through its centralised Integrated Development Environment. “By providing a single source for software management, the definition, deployment and maintenance of standards as well as the integration of third-party solutions, AVEVA System Platform justified its reputation as ‘the industry’s operating system’,” says Kotze.

Behind the scenes – the new MES. The dialogue box is the user interface regarding the KPIs of transfer notes. This is linked to a user-defined human-level process including responsibilities and responses being managed by Skelta BPM (now AVEVA Work Tasks) in the background, ensuring completion of all fields irrespective of the data sources to be accessed.

System development took about three months with a further two months of extremely thorough integration testing. Commissioning took two weeks and another two weeks was spent monitoring the interaction between the operators and the system. This was followed by two months of factory acceptance testing and finally a two-month stabilisation period.

Skelta BPM (AVEVA Work Tasks) is central to the implementation because it manages the workflow between people – it could be considered as process control at the human level. “No longer did we have to write multiple scripts in order to check if something had been done,” says Binza. “The application gave us drag-and-drop simplicity so that we could easily develop and maintain workflows while referencing various databases as well as the SCADA systems. It helped us enforce business rules and standards as well as traceability of users and production.”

The improved and focused implementation of phase 3 of the Pelo project made it easy for me to report about project Pelo, not only to the SA Mint Board, but to the SARB Governor’s Executive Committee as well.”

The Enterprise Manufacturing Intelligence (EMI) aspect of the project is not only helping SA Mint collate valuable decision and management support information but also provides access to the areas of mobile reporting, analysis and control as well as cloud computing and the ability to make sense out of big data. The next challenge for SA Mint is the design and implementation of phase 4 which will include the final products area.

But had it all been worthwhile? Had the project provided SA Mint with real business benefits? As mentioned earlier, on acceptance of this project, the board and steering committee of SA Mint insisted on verifiable checks and balances and appointed an independent auditing company to verify any business benefits the mint had realised through this exercise. Their findings are shown in the table below.



  • Enhanced production, performance reporting and the realisation of business goals
  • Easy enhancements and the flexibility to cope with changes in the manufacturing environment
  • Accurate reporting of up and down times (data integrity)
  • OEE reporting helps optimise plant availability and performance
  • Inventory optimisation though the availability and location of inventory items
  • Real-time production information measured per line and per machine
  • Limited manual reporting
  • Ease of integration with other systems, especially with the ERP system

The proven effectiveness of modern process control principles on the shop floor have been applied to driving collaboration across people, processes and systems by streamlining workflow, enforcing business rules and monitoring the responses of responsible parties. Embedding workflow software within the production environment enables SA Mint to implement standard operating procedures and corrective actions by structuring repeatable, managed responses to process exceptions across the enterprise.

This can be especially effective for processes and workflows that cross organisational boundaries such as operations, maintenance, laboratories and other business domains. Based on the success of this implementation, it’s probably safe to say that these operating principles will be replicated across the rest of SA Mint.
