Application of Kaizen-Kata methodology to improve operational problem processes. A case study in a service organization

Abstract

Purpose The purpose of this paper is to explore, study, analyze and implement Kaizen–Kata methodology in a service food organization (first-level restaurant), facing challenges in different operational processes that affect and influence the case company performance and customer satisfaction. Design/methodology/approach The service organization implemented Kaizen–Kata methodology to improve one operational problem process. A case-study approach was used in this research to understand the effects of the Kaizen–Kata methodology in solving problems in their operational service process. Different Kaizen–Kata techniques and tools (histograms, Pareto chart and Ishikawa diagram) using the Plan, Do, Check, Act improvement cycle framework were used. Findings Successful implementation of the proposed methodology reduced the main impact of the problem’s effects (customer’s complaints, process reworking, extra-cost, delays, among others). The effects of the problem were reduced on average by 70%. Some Kaizen–Kata routines were identified in a service process environment. Research limitations/implications The main limitation of the research is that this work is a just one-case study. A main generalization is not possible, because it involves a company within a company. Practical implications Some other service companies can use the Kaizen–Kata methodology to solve any kind of operational problem within their processes. Service managers can learn about the methodology to apply and improve their operational performance and handle customer’s complaints. Originality/value A continuous improvement manufacturing methodology was imported to apply in an operational service process. The Kaizen–Kata methodology contributed significantly to reduce delays, handle customer’s complaints, process reworking and deal with extra costs, among other operational problems’ effects. In addition to that, in the literature, most of the Kaizen applications are in manufacturing companies. To the best of authors’ knowledge, this was the first study of applied Kaizen–Kata in a service organization (a fast-food restaurant).

Employee's performance and Kaizen events' success: does supervisor behaviour play a moderating role?

“…The measuring instrument (questionnaire) was created following a comprehensive literature review. Specifically, van Assen (2020), Henrique et al (2021), Vo et al (2019), Su arez and Barraza et al (2021Barraza et al ( , 2011 were referred to create a more robust measuring device. In all, 32 manifest variables (MVs) were retrieved, and pilot testing was conducted by three academics and four industry experts on the final draft.…”

Enhancing Digital Presence for Maximizing Customer Value in Fast-Food Restaurants

“…One of these capabilities is the ability of digital strategic agility for fast-food restaurants. For example, fast-food restaurants can use agile/lean/kaizen methodology, a set of principles and techniques that can help them become more efficient and effective in their operations [61]. The restaurant's capacity to resist challenges is strengthened by digital strategy agility by maintaining operational dependability and effectiveness.…”

The integrated effect of Kaizen and innovation culture on the police performance: an empirical investigation

“…Most of these studies are theoretical research or case studies. In fact, applications of Kaizen in the service sector as a whole are extremely rare, as reported by Ishijima et al (2020) and Su arez- Barraza et al (2021). They recommended conducting more research in this field.…”
