This research critically evaluated the application of Six Sigma within Lonmin in the South African context. A probability sample was used; sixty-five (65) Six Sigma candidates were drawn from Lonmin with a Six Sigma population size of one hundred and twenty (120) employees listed in the Six Sigma database.

L IMITATIONS OF THE S TUDY

The response rate was slow due to survey completion and the commitment to survey delivery. The result was a good response rate; of the one hundred and twenty (120) individuals who received the survey via e-mail, only sixty-five (65) responded, which is equal to fifty-four percent (54%) of the population.

S TRUCTURE OF THE R ESEARCH

The medium of communication was another limitation. Due to the dispersed business locations and availability of respondents, this study was completely dependent on electronic communications (e-mail) and only employees were configured on the e-mail system. The recommendations made are based on the analysis and findings from Chapter Five.

C ONCLUSION

Chapter five discusses the findings and relates them to other similar studies in the field.

I NTRODUCTION

As a BPC initiative, Six Sigma focused on business processes to achieve significant performance improvements (Kettinger and Grover, 1995). Feigenbaum (1991) and Kaoru Ishikawa (1985) who contributed their propositions that form the basis for understanding the concept of Six Sigma.

T HE Q UALITY L EADERS

Feigenbaum (1991) defined Six Sigma as an effective system for integrating quality development, quality maintenance and quality improvement efforts of various groups in an organization in order to enable marketing, engineering, production and service at the most economical levels. . which enable complete customer satisfaction. Ishikawa (1985) argued that Six Sigma extends beyond the product and includes after-sales service, management quality, the quality of individuals and the organization itself.

The BPC Management Model suggested by Kettinger et al. 1995) considered environmental conditions and the organization's ability to manage change as important components for successful implementation. Process and change management practiced together with a change management environment contribute to the improvement of business processes and help ensure improved work quality, ultimately leading to improved customer satisfaction and organizational performance gains (Kettinger et et al. 1995).

The differences between a traditional and a Six Sigma culture can be characterized as shown in Table 2.6. Thus, the competencies that an organization built by using Six Sigma in it were sources of sustainable competitive advantage (Teece, D.J., Pisano, G. & Shuen, A., 1997).

F UTURE OF THE S IX S IGMA M ETHOD

Six Sigma tools and structure help organizations balance the drive for productivity with the need to innovate. To ensure the long-term prosperity and sustainability of the Six Sigma method, organizations must analyze and accept the strengths and weaknesses of the approach and use the Six Sigma concepts and tools appropriately (Pyzdek, 2004) .

C ONCLUSION

The review quantified the combination of Six Sigma and an economic framework to deliver transformational results (organizational culture, knowledge and business improvement). This gives rise to an empirical study of the adaptation of Six Sigma as a transformational tool at Lonmin in the context of the South African economy.

R ESEARCH S TRATEGIES

S AMPLING

The sampling technique chosen for this study was purposive non-probability sampling where the sampling units were based on personal judgment rather than where the sampling unit had a known, non-zero probability of selection ie. after selecting a purposive sampling technique for this study The next part of the research design was to determine the sample size.

S AMPLE S IZE

A disadvantage of this method was that the sample cannot claim to be representative, which limits the research results (Hair et al. 2005). The sample was drawn from management, process owners, six sigma personnel such as Black Belts and Green Belts, consultants who actively participated in the implementation of Six Sigma at Lonmin Platinum.

D ATA C OLLECTION A PPROACH

The population for this study included all Lonmin employees who were directly involved in Six Sigma projects, management staff, Six Sigma consultants, Six Sigma personnel such as black belts, green belts and process owners, the population size was one hundred and twenty (120 ) as extracted from the Lonmin Six Sigma database. These disadvantages did not apply in this study as the identified population was set up in the Lonmin email system and had access to computers.

D ATA C OLLECTION I NSTRUMENTS

The disadvantages of electronic questionnaire according to Bhaskaran (2008) are that not all your customers may have access to the email and employees may be wary of disclosing information online.

T HE Q UESTIONNAIRE AS A R ESEARCH T OOL

Q UESTIONNAIRE D ESIGN

The survey questionnaires were sent to a senior Six Sigma manager for quality and construct checking. Participants need to know that their privacy and sensitivity will be protected and what will happen to the data after the recording.

Q UESTIONNAIRE P RETESTING , R ELIABILITY AND V ALIDATION

The reliability of an individual measure determines the stability and consistency with which a research instrument quantifies a concept and helps determine the integrity of the measure (Sekaran, 1992). The content validity of a measurement instrument is the degree to which it provides sufficient exposure to the questions guiding the study.

D ATA C APTURING M ETHODS

To assess construct validity, both the theory used and the measurement instrument are considered. LISREL can provide the most appropriate and efficient estimation technique for a number of separate multiple regression equations estimated simultaneously (Hair et al., 1992).

D ATA A NALYSIS M ETHODS

Combining these variables into targets simplified the analysis and understanding of the data. Thus, the data analysis will initially use the tools available in Microsoft Excel for the final presentation.

C ONCLUSION

Simple tabulation, cross-tabulation and summarization of the relevant details of the responses were used to analyze the data. Descriptive statistics dealt with the presentation of data using frequency and central tendency statistical techniques.

Six Sigma as Change Management at Lonmin

In a large corporation with outstanding results, the formal structure of Six Sigma played a key role, establishing rules and procedures that certainly fostered a culture of continuous improvement. These factors fostered the sustainability of Six Sigma and the ongoing effort to insert projects into a body of knowledge that was slowly increasing in scope and quality [online].

Six Sigma Knowledge Management at Lonmin

Research conducted by PRTM found that companies need to select the right people from within their organization to provide both the subject matter expertise and the political influence needed to get things done. The study of how Six Sigma practices can lead to organizational knowledge creation capability and how this capability can lead to improved organizational performance showed that [Online].

Objective 1b: Determining the value of Six Sigma Knowledge Management at Lonmin The results are presented in Chapter 4, Section 4.3.2 on Six Sigma as Knowledge Management at Lonmin. The results showed that Six Sigma knowledge was not of great value to the organization, although a large proportion of respondents were still unsure.

The [online] survey, available at www.sixsigmacompamies.com (accessed July 1, 2010), found that employees trained in Six Sigma used their change management skills much more often than commonly thought. The results positively indicated that Six Sigma had the right focus and contributed positively to transformation and business performance.

A TTAINMENT OF R ESEARCH O BJECTIVES

The research report found that Six Sigma was a transformational tool that drove business improvement at Lonmin. The result showed that the implementation of Six Sigma had a positive effect on culture transformation and business improvement at Lonmin.

R ECOMMENDATIONS

Managers must be the architects of an organizational culture and climate that is conducive to continuous business improvement. Six Sigma methodology should be mandatory for any project approval and process deviation analysis.

F UTURE R ESEARCH

Project knowledge should be transferred through presentation to key stakeholders, and reports should be stored in a database. MBBs and BBs should be redirected to new business areas to gain experience in new areas and improve their leadership and team building skills.
