As a leading fuel pump and dispenser manufacturer in South and sub-Saharan Africa, Prowalco has strict service level agreements (SLA). Our software interface enabled them to continue operations with zero stops while maintaining the same level of service to clients. #### Key challenges The Legal Metrology (LM) Act ensures that consumers receive the quantity of goods declared by an importer, manufacturer or retailer on a pre-packaged item. It also ensures that instrument measurements remain accurate, within prescribed limits of error, where measuring instruments are used to conclude a transaction. In September 2019, the South African government changed the LM Act, directly affecting Prowalco’s work management operations. Some of the key challenges addressed were:​ - Calibration needed for specific master items being replaced/repaired.​ - Strict service level agreements(SLAs) being in place for work completion.​ - One of the first interfaces built solely with the new On Key Integrate technology.​ #### Our intervention - Pragma was approached to design and develop a software interface to help Prowalco adhere to the modified legislation. The On Key Integrate and Pragma operational teams developed the solution.​ - The team designed an interface to handle the creation of follow-up work orders in On Key, to re-calibrate the relevant assets.​ - The affected assets were flagged in On Key for the interface to identify them.​ - The Rabbit Messaging Queue service was used to establish when a work order changes to a predefined status and automatically creates a follow-up work order with all the fields populated as requested and a dynamic Work Required field.​ - The result is that a contractor can be notified and dispatched to the relevant asset and complete the equipment calibration within an acceptable time adhering to Prowalco SLAs.​ #### Value add - Continuous process monitoring ensuring pro-active Pragma intervention when necessary​ - 95% of work orders were created within 25 seconds of the trigger​ - Improvement in work order generation time – quicker action time, in turn, helps to achieve SLAs​ - No interface errors or problems have been experienced in the Production environment to date​ - Fluctuating and high amount of record changes in On Key are accepted and processed seamlessly. ​ #### Client background - Prowalco is a leading local manufacturer and supplier of fuel pumps and dispensers to various petroleum companies in South and sub-Saharan Africa. The company offers petroleum companies comprehensive repair and maintenance services and currently has Africa’s largest pump service infrastructure.​ - Prowalco has been an important client of Pragma for a number of years, with several existing interfaces. It was important to create confidence that a new interface request could be developed and delivered on time without any issues.​ --- Contact Us × ##### Book a demo × × #### Thank you for registering for the On Key Connection Day. × You will receive a follow-up email with a map to the venue and additional arrangements for the day.
