According to Töpfer and Töpfer (2007), six sigma includes a set of management techniques purposed to enhance businesses processes by significantly minimizing the likelihood that a defect or an error will happen. Six sigma can be incorporated into the process of increasing employee motivation. Particularly, the technique can be used to minimize variances in the process by helping individuals eliminate waste in time management, hence minimize downtime. Also, the technique may be used to foster personal leadership and managerial competencies that will facilitate motivation in the organization. Also, by helping eliminate waste in personal finance, the technique can help enhance employee motivation.

Evaluation of Control Chart and Process Metrics

The control chart is a graphical illustration of how a process in business changes over time. On the other hand, process metrics refer to measurements applied in tracking a business process’ performance. They are likened to key performance indicators (KPIs) in that they are used in measuring the performance of a task and if it is achieving the defined goals.

Executive Summary

The six sigma can be used to minimize variances in the process by helping individuals eliminate waste in time management, hence minimize downtime. Also, the technique may be used to foster personal leadership and managerial competencies that will facilitate motivation in the organization. Also, by helping eliminate waste in personal finance, the technique can help enhance employee motivation.

An evaluation of control chart and process metrics based on SPC methods shows that the control chart presents a situation that cannot be regulated and an error has occurred. Using the SPC methods, the alpha risk shows the risk related with attractive process that cannot be controlled when in actuality falls in the control limit. Moreover, a beta risk includes a hazard related to the process that is in control but in realism, is not. According to Qiu (2013), numerous shared perspectives assume that data presented in a control chart is distributed normally and that the data is in control so as the control chart to be useful. The used SPC formula is as illustrated below.

where Cp, is the rate of ability or capability

Where s represents the population’s standard deviation which is derived from with s-bar showing the mean deviation for every coherent subgroup and c4 representing the alteration numerical coefficient.

An in-depth analysis of the Six Sigma tool shows that it could be beneficial in increasing employee motivation. The technique may reduce possible variances in the process such as overtime, premium time and get-away pay. Issues such as under and over payments and the duration and effort it would take to rectify them would significantly reduce. Additionally, the technique will help employees reduce waste in personal finance mostly during their free time, which could motivate them. Additionally, the technique would be beneficial because it would instill a sense of belonging in the employees, which could keep them motivated.

The statistical process control (SPC) project involved a control chart and process metrics. Some of the most significant process metrics integrated into the project included process capability index and process capability.

The process capability in the SPC project represented the quantifiable features of the business process to a certain degree. The formula used to calculate the process capability is as illustrated below.

Where,

LSL = Lower Specification Limit, USL = Upper Specification Limit

LSL = 400

USL = 600

Std. Dev = 16.67

Mean = 526.2

In this business process, some variables were needed to be included for the determination of the process capability within the SPC Project. The obtained answer following multiplication together with variable’s division was 1.722.

Regarding the Process Capability Index, it showed how firmly the business process was capable of producing the yield to its total specification. The adopted formula in the calculation of PCI was:

Several variables were integrated in the determination of the process capability index’s actual value. The derived answer following multiplication and division of the integrated variables was 2.237.

The following formula was used to calculate the performance Pp rate:

Where s represents the whole data’s standard deviation

The difference between Cp and Pp was established within the process of calculating s. In the calculation Ppk illustrated the comparisons with the calculation of Cpk. The capability rate for Ppk was determined by adopting the following formula:
