Process Improvement & Control

Process Improvement

Six Sigma is an organizational and management approach that focuses on customers, data and people to create quality in products, services and processes. Six Sigma has its origins in the production industry but is used in many different industries today. The purpose of Six Sigma is to organize the company and the company’s processes, products and services, so that the company is better equipped to meet customers’ expectations with the least possible cost. AN GROUP has worked with Six Sigma for many years and taught employees to use DMAIC. All of our consultants have several years of experience working with corporate processes and are well-equipped to increase earnings by identifying and analyzing problems through structural methods and tools. 


Six Sigma is often associated with the project model DMAIC. The project model is used for problem solving as well as process improvements. DMAIC is based on, and an extension of, PDCA (plan, Do, Check, Act), which focuses on making continuous improvements. However, DMAIC has a broader focus that deals with larger and more complex issues. The project model has helped solve major challenges for companies and contributed to streamlining processes. It is most often seen in practice that the model is iterative as you learn along the way and thus can jump between the phases. AN GROUP has experience with solving complex problems for our customers using Six Sigma methodology. 

Statistical Process Control

Statistical Process Control (SPC) is an industry standard practice for measuring and controlling quality during the manufacturing process. The objective of SPC is to establish a controlled manufacturing process using statistical techniques to reduce process variation. Reducing variation contributes to improved quality, lower costs (such as waste, scrap, rework, claims) and better insight into the capability of the process. AN GROUP has helped several organizations become more efficient and arrive at a controlled process by ensuring measurements and data being registered correctly. We aid in registering process adjustments as a way to follow up and evaluate on the effect, as a key part of success.
