  • 4. NUS Presentation Title 2001Introduction – BackgroundNSD is not an easy task.• Involves adaptive combinations of various elements (Ostrom et al., 2010).• Success rate is as low as 58% (Griffin, 1997).2New Service Development (NSD) is at the heart of service firm’scompetitiveness.• Enhances the profitability, attracts customers, and opens a newmarket (Storey and Easingwood, 1999).Services are becoming the front edge of the economy.• 80+% of jobs in developed countries (Tidd and Hull, 2003).• Huge growth in developing countries (Metters and Marucheck, 2007).
  • 5. NUS Presentation Title 2001Tools and equipmentProcedures andmethods defining therelationship of tasksPeople with skills,training, andmotivationIntroduction – Motivation3• There are few studies focused on the tools employed for successfulNSD (Menor et al., 2002).• The determinants of tool adoption are unclear (Kettinger et al, 1997).• Formal tools especially designed for NSD are few (Menor et al., 2002).(Source: Paulk et al., 1995; SEI, 2010)

  • 8. NUS Presentation Title 2001Study 1– Literature Review5Qualitative literature review has its limitations.• Subjective judgements (Kunz and Hogreve, 2011).• Individual interests (Baumgartner and Pieters, 2003; Podsakoff et al., 2005).A number of NSD literature reviews have been conducted (e.g., Johneand Storey, 1998; Menor et al., 2002; de Jong and Vermeulen, 2003; Droege et al., 2009;Papastathopoulou and Hultink, 2012).• Current developments in the field.• Future research opportunities.Bibliometric analysis complements qualitative NSD reviews.• Quantifiability and objectivity (Nerur et al., 2008).• Unveil undetected research themes (Kunz and Hogreve, 2011).To provide a quantitative review of the NSD research and to suggest future researchopportunities based on bibliometric analysis techniques.

  • 17. NUS Presentation Title 2001Study 2– Literature Review10NSD tool is defined as a precisely described method for supportingand improving NSD processes (Brady et al., 1997).Various NSD tools have been proposed by researchers.• Tool plays an enabling role in the innovation process (Chiesa et al., 1996).• Prototype new offerings, identify customer needs, and trouble-shoot problems (Shostack, 1984; Alam, 2002).Existent NSD tool studies have their limitations.• Focus on one particular NSD tool.• Few empirical descriptive studies.• Efficacy of NSD tools is mainly demonstrated by case studyresearch (e.g., Wind et al., 1989; Thomke, 2003; Bitner et al., 2008).To investigate (1) what are the common NSD tools? (2) How are they used inservice firms? and (3) Whether their use improves NSD performance?
  • 18. NUS Presentation Title 2001Study 2– What are common NSD Tools?11Services result from cross-functional efforts of operations andmarketing management (Zeithaml et al., 2009).• Market tools: to engage customers for a better understanding oftheir needs and commercial potentials.• Development tools: to support development efforts of technicaldesign and testing.Idea generationand screenBusiness andmarket analysisService design Service testingServicelaunchingMarketToolsBrainstorming ●Focus Groups ●Benchmarking ●Scenario Planning ●DevelopmentToolsConcept Testing ● ●Quality Function Deployment(QFD)● ●Service Blueprinting ● ● ●Structured Analysis andDesign Technique (SADT)● ● ●● main role n ● supporting role
  • 19. NUS Presentation Title 2001Study 2– How NSD Tools are Used? (1)12Industry: financial service.• Financial institutions are active innovators (Menor and Roth, 2008).• Financial services are standardized and available off-the-shelf, andthis provides opportunities to use NSD tools (Easingwood, 1986).Data collection strategy: large-scale survey.• Able to unveil NSD tool usage patterns and effectiveness.• Invitation letter  questionnaire 1st/2nd reminder  phone call.Location: Singapore and Taiwan.• Subtle differences in NSD practices (Song et al., 2000).• Post-hoc analysis passed Mann-Whitney U test (Siegel and Castellan, 1988).Unit of analysis: NSD projects conducted in recent 3 years.• 75 projects for analysis (Singapore: 34 and Taiwan:41).

  • 25. NUS Presentation Title 2001Study 3– Literature Review17NSD tools have not been widely adopted.• Study 2 shows that only 3 tools are used by 70%+ respondents.• Tool usage level is not high in service industry (Barczak et al., 2009).• Service firms are less likely to introduce new elements (e.g., tools)(Damanpour and Gopalakrishnan, 2001).To conceptualize and empirically test a theory-driven model thatattempts to explain antecedents of NSD tool adoption.Ajzen’s (1985) Theory of Planned Behaviour is adapted.• Popular psychological model with high predictive power (Ajzen, 2011).• Frequently used to study organizational adoption of processinnovation.

  • 30. NUS Presentation Title 2001New Service Development Maturity ModelSTUDY 4
  • 31. NUS Presentation Title 2001Study 4– Literature Review22To develop a maturity model which facilitates the evaluation ofNSD process and shows direction for continuous improvement.The execution quality of NSD process is critical.• Good execution reduces miscommunications, eliminates non-value-added activities, and improves project flows (Froehle et al., 2000).Maturity model can be used as a process management tool.• High maturity leads to consistent and repeatable processes (Paulk etal., 1995).• Maturity model assesses current situation and provides guidelinesfor continuous improvement (Niessink et al., 2005).There is a shortage of NSD process assessment tool.• Determining project execution capability is something less than ascience but more of an art (Crawford, 2002).
  • 32. NUS Presentation Title 2001Study 4– Methodology23-1• Aim: (1) assess current NSD process; and (2) diagnose opportunities forcontinuous improvement.• Audience: organizational unit which is responsible for NSD.Step 1: Define aim and specify audience• Four process areas are solicited from NSD success factors: strategymanagement, process formalization, knowledge management, andcustomer involvement.• Maturity dimensions are constructed to capture critical aspects.Step 2: Select process areas• Five maturity levels are constructed for each process area by referring torigorous theories which model evolutionary path of capabilities.Step 3: Select maturity levels• Determine behavioural characteristics associated with different maturitylevels of each process area.Step 4: Formulate maturity grid
