Integrated Business Planning & Supply Chain

Integrated Business Planning (IBP) and Supply Chain Management are extremely important in the current era of globalisation. Nobody is an expert in everything, so we offer programs customised to your needs. We focus on two areas of high importance:

Integrated Business Planning: learn how to integrate Supply Chain Management, Lean Manufacturing and Six Sigma into your company's business strategy. We help you analyse and improve your business processes from demand planning all the way to execution in the manufacturing plant. Areas we look at include Sales & Operating Plan, master scheduling process, inventory accuracy, supplier performance, daily schedule adherence, new product introduction process, value stream mapping and workplace organisation.

Sales & Operations Planning (S&OP): the success of a company depends on how it manages and balances demand and supply, and how the organisation takes and executes decisions to keep this balance in line with company strategies and KPIs. S&OP is a cross-functional, formal monthly planning process designed to reach consensus on a single operating plan that matches demand with supply, balances volume and mix, and reconciles operational plans with strategic and financial business goals. If you are new to S&OP, we can help you understand what it is about and how to implement it; if you have already implemented S&OP and want to take it to the next level, we can share our experience and best practices.

Courses we offer

  • Class A Enterprise Resource Planning (3 days)
  • Introduction to Sales & Operations Plan (S&OP) (2 days)
  • Effective Implementation of S&OP (2 days)
  • Inventory Accuracy Management (1 day)

Customer Experience

Customer experience has emerged as the single most important aspect in achieving success for companies in all industries. With products becoming commoditised, price differentiation no longer sustainable, and customers becoming more demanding, companies are focusing on delivering superior customer experiences.

Customer experience is not only about customer service excellence. It is deeply rooted in the company's culture, how products are made, and how services are generated and delivered to customers. How a company runs its operations affects its customer experience level. With a structured mapping process, companies gain an understanding of what causes satisfaction or dissatisfaction in a customer's experience, and management can then implement changes appropriately.

The human component of an experience is as important as the physical one. A change in a company's culture and its employees' mindsets is an effective way to improve the customer's experience on a large scale. Customer experience can only change when it becomes a business's top priority.

We help your business by providing the skillsets and solutions to support the transformation. Along with developing digitalisation and automation tools to organise company and customer information better, we help companies implement proven methodologies, including Lean Six Sigma, to improve customer perception, satisfaction and commitment.
