Unleashing hidden potential: customer engagement in modular service innovation

Purpose This paper aims to explore the role of customer engagement during the production of services in a modular innovation. Modularity can be used to explain the structure and relationship in services innovation. Design/methodology/approach The authors explore the theory of modularity focussing on the context of consumer engagements. They adopted ideas from product modularity and approach services using modular principle. Findings Contrary to the extant literature, the authors are content that the transactions between the participants were mainly conducted at thick crossing points. By focusing on thin crossing point, the service provider will achieve better overall service structure. Research limitations/implications There is a need to focus on specifying interface to define how service modules and service providers interact with the customer within the service. Practical implications By engaging customer, modular principle can help firms achieve cost efficiency, higher product and process variety, as well as better response to individual customer needs. Originality/value This paper scrutinises the engagement of customer and conceptualises the role of customer in modular innovations that have been previously neglected.

INTERACTIVE LANGUAGE TEACHING THROUGH DISCUSSIAN IN A SECONDARY SCHOOL CLASSROOM

Background: Discussion is extensively used in native and foreign language classrooms at school and is viewed as language an instrument for enhancing capacity of students in different communication situations. Noteworthy is the fact that researches employ a range of different terms to refer to the concept synonymously: polemics, debate, public polylogues etc. Moreover, there is a lack of common understanding regarding characteristics of discussion as a method of interactive learning as well as its types in the context of different national educational systems. Purpose: The purpose of the article is to revisit the meaning of the concept «educational discussion» based on the analysis of definitions offered by psychological, didactic and linguistic researches. The objective of the study is to characterize discussion as an interactive teaching method and to determine those content components of teaching Ukrainian and Spanish in high school which are appropriate for applying the method of discussion. Results: Our theoretical speculations have led us to the conclusion that an educational discussion method in language pedagogy should be viewed as a special method aimed at building communicative and strategic compe­tence of the student. Empirical researches carried out by the authors based on questionnaires, observations and interviews enable us to suggest that the method of discussion in teaching Ukrainian and Spanish has to be used in different stages of secondary education. The results of the survey of teachers-practitioners have shown that discussion appears effective for learning any aspect of the language (vocabulary, stylistics, grammar). The course of the discussion (debate, polemics) provides the information for monitoring the progress in students’ speaking skills. The advantages of the discussion method lie in the awareness of the role of dialogue in communication and necessary enriching the vocabulary. It is through educational discussion that the students practice new grammat­ical constructions in live communication with interlocutors and correct their own and others’ mistakes. Therefore, discussion has significant advantages for the development of communicative competence of the student at all stages of secondary education. Comparing the views of leading experts in Ukraine and Europe made it possible to present the main charac­teristics of the discussion as a method of interactive language learning: individual and collective development of learners’ personality, cooperative interaction of interlocutors, organizational function in the educational process; variety of forms of classroom work. Discussion: Interactive language learning and collaborative interaction of communication partners provide intensive language learning for students. By analyzing, criticizing, approving of the statements of the participants in the discussion, students develop communicative and strategic competence. At the same time, the use of the method of discussion is extremely effort-taking for the teacher, since requires unconventional techniques and creativity.

Development of Prefabricated Modular Retrofitting Solution for Post-World War II Buildings

Residential and public buildings are one of the essential energy consumers. The majority of European buildings were constructed within the period from mid-1950ies to the late 1990ies. Currently the retrofitting process is too slow. The main barriers are complicated retrofitting process, variety of available technologies as well as precision of estimated energy savings calculations. This paper is prepared in scope of work done within the European Regional Development Fund project “NEARLY ZERO ENERGY SOLUTIONS FOR UNCLASSIFIED BUILDINGS”. The main aim of this study is to develop full modular retrofitting process based on 3D laser scanning minimizing time consumed for architectural project development, on-site construction works as well as to ensure correct energy simulation. Paper presents results of Latvian case building 3D scanning results, architectural project development specifics as well as selection of optimal thermal insulation layout and energy simulations. Study analyses main barriers for wide implementation of prefabricated panels.

Evaluating TRIZ as a Provider of Provocative Stimuli

The Theory of Inventive Problem Solving (known by its Russian acronym TRIZ) is used across the globe to help engineers working on product design and development. In previous papers the authors developed a Function-Based TRIZ method and began a validation process. A single innovative feature was identified in a sample of innovative products, and these features were traced backwards on the Function-Based TRIZ matrix. The Function-Based TRIZ matrix was deemed successful in cases where any inventive principle suggested by the matrix could have produced the innovative feature. During this process, the authors observed that no matter which principle was used, some mental leap was needed to apply it. Additionally, many different inventive principles can lead to the same concept. This paper examines a new hypothesis: that the provocative stimulus presented by any randomly selected inventive principle facilitates concept generation just as effectively as using the historical contradiction matrix to guide inventive principle selection. This paper presents a study on the benefits of using the TRIZ contradiction matrix to select the “correct” principles during concept generation. During this study, participants were asked to come up with concepts using one of two TRIZ matrices: the real one that contains historical knowledge from an extensive patent search, or a randomly populated one. The results of this exercise were then examined using modified versions of two concept evaluation metrics set forth by Shah: quantity and variety. This paper offers two contributions to the field. The first is a step toward understanding the role and importance of conflict mappings in TRIZ and TRIZ-like problem-solving methodologies. The second is a method for evaluating process variety (as opposed to outcome variety) when TRIZ is used to generate ideas.
