  • Innovating for Joint Productivity Jan H. S. FOSSE - Deloitte Consulting, Norway Stein E. WILL – Get, Norway Tor W. ANDREASSEN - BI Norwegian School of Management, Norway Carl BRØNN - BI Norwegian School of Management, Norway ABSTRACT Firms innovate to stay competitive but the underlying variables governing the mechanism for short term and long term value creation are only understood to a limited extent. In this study we specifically investigate the long-term effects of productivity improvements that either take the firms’ or customers’ interests into account. Our point of departure is previous research by Parasuraman (2002), Rust, Moorman and Dickson (2002), and Vargo and Lusch (2004) on value creation for modern firms. The relationship has been operationalized through a synergistic model that includes both the firm’s and the customer’s input-output relationship. Based on dynamic simulations the results are surprisingly clear. When the firm considers the customer as a partner in value creation, optimal value is gained by providing mutual productivity improvements and long-term profitability is strongly improved. If the firm is self- centric with its own bottom-line as focus, the firm is less profitable in a long-term perspective. Thus, this research confirms and expands the service dominant logic in a managerial perspective. Jan H. S.

In improving quality) Rust et al 2002: 9). This order to reap the long-term benefits notion is also strongly supported within the managers need to make sure that the firm market orientation and strategy literature survives in the short term. In other words: (Rust et al. 2002). today’s decisions may impact the long- term conditions to survive. For service In a recent article, Parasuraman firms one typical trade-off is cost cutting (2002) suggested that higher levels of today and its potential impact on customer service quality can be obtained not only satisfaction tomorrow.

Because dissatisfaction (e.g. customer service) in most services are co-produced service the following periods. At the heart of this quality will “influence outputs from both a discussion lies organizational efficiency company and customer perspective.” and effectiveness. Parasuraman (2002) defines customer output as service performance and There are a number of definitions satisfaction, and company output as sales, of organizational efficiency and effective- profits and market share. Finally, and in ness. We define effectiveness as “the keeping with the disconfirmation of degree to which an organization realizes expectation paradigm (Oliver 1980), its goals” (Etzioni 1964). The efficiency of customer satisfaction should increase an organization is measured by “the (alternatively customer dissatisfaction de- amount of resources used to produce one crease) with increased perceived service unit of output” (Etzioni 1964, p 6). The quality. Today there are few, if any, argument is that there is a distinction here: research studies that focus on the impact on the one hand, productivity (efficiency) is of productivity and performance when the ‘amount of resources used to produce customers are part of the value creation a unit of output’ and on the other hand, process. The purpose of this study is to fill effectiveness is the ‘degree to which an this gap in the literature. The research organization realizes its goals’. (Etzioni question that guides our study can be 1964, p 8). Fundamental to this thinking is expressed as: What is the long-term the well-developed and documented ser- impact of firm or customer focused vice quality -> customer satisfaction -> productivity innovations? We will address performance link, (see for example Fornell this question in two steps. First, from the 1992; Rust et al. 2002; Rust and Zahorik literature we will identify key relationships 1993; Rust et al. 1994).

As alluded to above, there are three ways to an improved bottom line: Customers’ use of technology to increase revenue, reduce costs, or a produce and receive the service is often combination of these. According to Rust, referred to as self-service technology Moorman and Dickson (2002) firms that (SST), i.e. Technological interfaces that primarily focus the revenue side will have enable customers to take advantage of a a higher return on investment than any of service without any involvement from the other two options.

Innovations for productivity in accordance with the service dominant logic (i.e. maximize for customer productivity) are discouraging in the short term but rewarding in the longer run as they produce results that far outperform the initial losses. From this we can learn that despite a reduction in firm productivity the long-term effects of increased customer productivity far exceed the firm’s initial loss.
