As the airline industry continues to rapidly expand and evolve, today's airlines leaders are faced with the challenge of balancing long term strategies with short term solutions. Customer satisfaction has become significantly important for airline operations and as a result service quality has also gained paramount importance in this sector. Lean's customer-focused theme for improving service quality has gained a momentum in services, however, Lean deployment within the airline service sector is generally a long way behind manufacturing and health services. These factors have motivated research into investigating Lean phenomena within a leading UK airline company. For quantitative and qualitative data analysis, 9 cases were collected from 3 internal departments of the airline company, 35 semi-structured interviews were held, and 220 survey questionnaires were circulated of which 180 were returned. Within-case and cross-case analysis techniques were applied and, to develop a framework and 5 key relationships were identified. This study’s contribution is in the area of Quality Management as it: (a) highlights the role of ‘customer value’ and ‘engagement value’ in the domain of technical and functional service quality attributes; (b) maps cost-quality-delivery relationships through linking Lean improvements to its results; and (c) constructs an ‘outcome-driven’ framework from the findings. Ultimately, this research provides knowledge and understanding of how an airline company deploys Lean as business strategy to improve their service quality. The novelty of the research in terms of deliverables is two-fold: firstly, it establishes framework linking Lean improvement initiatives to its results, which extends to the sustainability, commitment, future profitability and market share characteristics of improvement results; and secondly, it provides a tool, which could assist key decision makers in evaluating the results of the Lean initiative to provide better understanding for Lean deployment. Key words: Lean services; business improvement strategy; service quality improvements; quality management; airline services; customer satisfaction; employee satisfaction.

For these purposes, tools such as process maps, flowcharts, indicators, system layout planning tools, and 5S implementation are used, supported by training sessions for process participants. As a result, customer complaints were reduced by 0.13% per month, and the number of work orders handled by the site increased by 0.38% per month. Moreover, a 0.32% increase in man/hour productivity was reported, leading to a 44.32% decrease in Duster vehicle delivery times.

Lean has become a widespread concept within various industries. It originates from the production system at Toyota and focuses on maximizing customer value and eliminating waste. It has been adopted throughout industries as a consequence of stiffening competition and higher customer demands. From Toyota, the concept spread to other car manufacturers and then further to other manufacturing industries. In recent years, the Lean concept has spread to more intangible settings, initially to service functions within the manufacturing companies and later to pure service oriented industries such as healthcare, banking, and insurance. Most recently, the concept has been adopted in IT businesses as a mean to gain competitive advantage. A lot of research on the Lean concept has been concerned with issues such as implementation and the operational application of the concept. Even though the purpose of the concept is to increase the operational performance and to deliver high customer value, little emphasis has been put on research related to performance measurement in a Lean service setting. While some research regarding modern performance measurement frameworks exists, a weak link is identified between the two research areas (Lean and Performance measurement). This study has focused on the specific IT service setting at Company X and their Lean initiative. The purpose of this study is to complement Company X’s Lean initiative with recommendations related to an area currently not emphasized by Company X, measuring performance improvements due to their Lean efforts. Company X is especially interested in the linkage between operational improvements and the financial outcomes. This study employs a holistic view in order to gain a wide understanding of the organizational context and the business in general. It has been paramount for this study to understand the organizational setting, the theoretical concepts, and the interplay between them. As a mean of fulfilling the purpose, the case study methodology has been employed throughout this study. The research was initially defined by its objectives and delimitations. Interviews, observations, and a content analysis contributed to the overall organizational knowledge which was deemed crucial for the end result. The organizational knowledge together with the understanding of the theoretical concepts and the exploratory benchmark study has been the basis for the analysis and recommendations. The study has rendered in recommendations regarding how measurement activities should be designed and employed in Company X’s Lean setting. This study suggests that a limited focus should be put on general measuring activities in Tieto. More specifically, little focus should be put on attempting to determine a correlation or linkage between the operational improvements and financial outcomes. The study further suggests a separation of the organizational KPIs into steering (operational) KPIs and monitoring (financial) KPIs. This is suggested in order to have operations steer the organizational performance as well as cement the Lean concept within the organization. Overall, a focus should be put on measuring processes rather than financial data.

This thesis is improving a support process with lean in a fast-growing IT startup. It investigates how processes in the service area can benefit from process improvement with lean, and the challenges and similarities that already exists in a startup with a background of agile and lean development. This is studied with both qualitative and quantitative data in order to create a broad point of departure. Common lean tools are used such as value stream mapping, 5S and, Pareto diagrams, but also from the quality management toolbox such as process mapping. The resulting analysis creates the foundation for a more efficient process which the startup can use to scale, measure and control. Lean is found to be a very suitable theoretical framework for this purpose, but some main concepts are found to not translate very well from the manufacturing industry where Lean once originated.
