Development of Swim Lane Workflow Process Map for Sales and Inventory Workflow Management Information System: A Case Study of Petrospan Integrated Services, Eket, Akwa Ibom State, Nigeria

Adanna Ngozi Ezeonwumelu, Constance Kalu, Enyenihi Henry Johnson


According to experts, sales workflow management system can impact overall sales effectiveness, vis-à-vis, improve the efficiency of sales people, accelerate sales follow-ups, increase sales and reduce costs. On the other hand, inventory management system can be used to avoid product overstock and outages by tracking inventory levels, orders, sales and deliveries. This paper identified the problems prevalent in the existing sales and inventory flow management system at Petrospan Integrated Services in Eket, Akwa Ibom state, Nigeria. Then, the analysis and design of a new sales and inventory workflow management system for the Petrospan Integrated Services was presented. The “as-is” sales and inventory workflow management system was first modelled using swim lane process flow map. Then, the swim lane process flow map was also used to develop the “to-be” or “should-be” sales and inventory workflow management system specifically to address the shortcomings of the “as-is” workflow management system as well as to facilitate the development and deployment of automated sales and inventory management workflow management system at Petrospan Integrated Services-Sales Eket.
