Energy Consumption Optimization Based on Six-Sigma Tool (DAMIC) and Energy Value Stream Mapping
Published in Shwetank Avikal, Amit Raj Singh, Mangey Ram, Sustainability in Industry 4.0, 2021
The six-sigma project starts with the identification of CTQ (critical to quality). In the present case, the CTQ is to minimize the energy conservation in the existing system. The tools used for the DMAIC in the selected process flow (Figure 7.5) are as follows:Define - The method, the customer’s voice and their needs, (SIPOC Diagram)Measure - The current process and the related data are collected; measure process capability ‘as-is’. (Current value stream mapping)Analyze - Data to assess and measure causal-effect relationships. Identify relationships and aim to take into account all aspects. (Fishbone diagram, Time study).Improve - The current data analysis method uses techniques such as experimental design, error evaluation and standard work to develop a new, future state method. (Future Value stream map)Control - The future state mechanism ensures that any deviations from the target are rectified before errors occur.

In the Six Sigma world, this is viewed though the use of process behavior charts (or control charts)—visual representations of the process with all its flaws and exceptions. Lean projects use current-state maps to obtain a similar visual picture of the voice of the process. The voice of the customer is defined as the ultimate customers’ expectations in relation to quality, cost and delivery. Six Sigma uses critical-to-quality characteristics (CTQs) to define, measure, and set goals defined by the voice of the customer. Lean uses future-state maps for the same purpose. It doesn’t matter which methodology you use at any given moment, as long as you are striving to satisfy the “value proposition.”
What Is Lean?

It should be the best, safest, easiest, most cost-effective, and productive way to complete the task. It preserves the corporate knowledge for the benefit of everyone who will work the process in the future.It provides the basis for measurement against a standard.It provides the basis for training future team members.It ensures meeting the customer critical to quality (CTQ) requirements.It minimizes operator-driven variability.

In the define phase, importance in the context of the organization is discovered. Major tasks of this phase are Project selection, Strategic planning and decision, Project charter, Process Mapping, and Project management tools. In the first step, critical to quality factors (CTQs) also should be identified which have major importance. The main theme should be to understand CTQs and spreading it to the whole organization and work floor to make it further better to improve profitability and customer satisfaction. The measure phase calculates the current sigma level of the company by gathering information and data and measures the process capability to compare it with the customer requirements. In this phase, process variables that are to be measured for the identification of process, the level is selected, the data sources for the collection of data are identified, plan for the collection of the data is prepared and the measurement process for the proper measurement of the whole process is implemented. Collection of accurate and original data for the calculation of the actual performance of the process performance is the main objective of the measure phase(Tennant, 2001).

Lean Six Sigma (LSS) aims to drive business process improvements through adopting the key features of both Lean and Six Sigma and combining these features in to a single approach towards business performance enhancement (Corbett, 2011; Thomas, Francis, Fisher, & Byard, 2015b). In so doing, companies focus on adding value and then systematically reducing and removing waste (the lean element of the approach) whilst employing Six Sigma to focus on and eradicate the Critical to Quality (CTQ) issues that affect an organization (Drohomeretski, da Costa, de Lima, & de Rosa Garbuio, 2014). In applying this combined approach, LSS aims to achieve fast flexible flow of goods and services whilst systematically eradicating any issues that could adversely affect the quality of that product or service. LSS employs the traditional Six Sigma DMAIC cycle where, Lean tools can be integrated in to the phases to produce a range of benefits for the customer. Utilising the correct tools for the specific area of need is critical to yielding the improvements desired (Thomas, Barton, & John, 2008). A further detailed discussion on Lean Six Sigma is provided in the next section.

The define phase started with the definition of critical to quality requirements (CTQ). The requirements chosen in this phase were the NP and ADT defined earlier in this section. However, despite the fact of also being considered a key performance indicator (KPI), the NP is difficult to measure monthly due to the use of coupons that are purchased and used by customers at different moments. Thus, the current project treats variability issues and capability analysis only for the ADT, with the premise that NP increases with a reduction of the ADT. The SIPOC diagram in Figure 1 displays the global process workflow and assists the understanding of how inputs, outputs and stakeholders are related to it.
