Although efforts to optimize formal processes and integrate Agile methods into development have led to more efficient innovation systems, a large skill gap remains that cannot be overcome by tools and processes alone. To explore the extent to which companies are (or are not) engaging in training to address those skill gaps, interviews were conducted with 30 senior R&D managers from Fortune 1000 companies. The results indicate that even though senior managers’ view of innovation success factors is more focused on human capital than in the past, innovation training rarely happens—80 percent of the companies in our sample reported rarely engaging in structured training to build innovation competencies. We offer some recommendations for addressing this gap.}, number={2}, journal={RESEARCH-TECHNOLOGY MANAGEMENT}, author={Michaelis, Timothy L. and Markham, Stephen K.}, year={2017}, pages={36–42} } @article{lee_markham_2016, title={PDMA comparative performance assessment study (CPAS): Methods and future research directions}, volume={33}, DOI={10.1111/jpim.12358}, abstractNote={Best practices data are critical for managing and researching new product development.

We‐ness is the shared sense of togetherness family members feel toward each other. We apply we‐ness to NPD as the construct through which people share knowledge at the team, between‐team, and between‐organization levels. The results support the hypotheses that we‐ness increases knowledge sharing and that knowledge sharing increases product performance. In this study, we used regressions to analyze the hypotheses. We found that the greater in‐team we‐ness (H1, t = 3.786, p = .000), between‐team we‐ness (H2, t = 5.411, p = .000), and between‐organization we‐ness (H3, t = 2.940, p = .004) activities there were, the more knowledge sharing in NPD. Results also indicate that knowledge sharing is related to better NPD performance.This paper contrasts team and family as the foundation metaphor to organize people engaged in product development. We argue the team metaphor can be counterproductive in settings where difficult decisions must be made. Teams can lead to individual members suppressing their opinions to “help” the team achieve its goal. Members are expected to sacrifice for the good of the team. That can be adaptive when the task is straightforward.The family metaphor suggests that the group sacrifices for the individual. In a family environment, members protect minority opinions, and in cases where complex, ambiguous decisions must be made individual expertise and insight may come from one person. High‐trust family‐like settings can facilitate sharing sensitive information and norms that can be challenged. The family metaphor suggests a more flexible and tolerant approach to new ideas. At the same time, it is recognized that families can have dysfunctions that can detract from performance. Therefore, managers must carefully apply the use of family‐like settings.The importance for family‐like approaches across organizations seems to be more important as technology complexity increases. Between‐team we‐ness was revealed significantly higher in goods manufacturers than service firms in this study. Small companies need to make extra effort to increase between‐team we‐ness.The idea of approaching product development from a family relations perspective opens up new alternatives for managing people in teams, between teams, and even between organizations. MFT tools to address behaviors and individual performance issues increase the number and nature of managerial tools to increase product performance.}, number={6}, journal={JOURNAL OF PRODUCT INNOVATION MANAGEMENT}, author={Markham, Stephen K. and Lee, Hyunjung}, year={2014}, month={Nov}, pages={1291–1311} } @article{markham_lee_2013, title={Product Development and Management Association's 2012 Comparative Performance Assessment Study}, volume={30}, ISSN={["1540-5885"]}, DOI={10.1111/jpim.12025}, abstractNote={Results of Product Development and Management Association (PDMA)'s Comparative Performance Assessment Study are presented from 453 companies.

This research explores differences in formal new PD practices among three project types—incremental, more innovative, and radical. Using a sample of 380 business units, this research investigates how development practices differ across these three classes of innovation with respect to the formal PD process, project organization, PD strategy, organizational culture, and senior management commitment. Our results diverge from several commonly held beliefs about formal PD processes and the management of radical versus incremental innovations. Our results indicate that radical projects are managed less flexibly than incremental projects. Instead of being an offshoot of less strategic planning, radical projects are just as strategically aligned as incremental projects. Instead of being informally introduced entrepreneurial adventures, radical projects are often the result of more formal ideation methods. While these results may be counterintuitive to suppositional models of how to radical innovation happens, it is the central theme of this research to show how radical innovation actually happens. Our findings also provide a foundation for reexamining the role of control in the management of innovation. As the level of innovativeness increased, so too did the amount of controls imposed—e.g., less flexibility in the development process, more professional, full‐time project leadership, centralized executive oversight for new products, and formal financial assessments of expected NP performance.}, number={2}, journal={JOURNAL OF PRODUCT INNOVATION MANAGEMENT}, author={Holahan, Patricia J. and Sullivan, Zhen Z. and Markham, Stephen K.}, year={2014}, month={Mar}, pages={329–345} } @article{markham_2013, title={The Impact of Front-End Innovation Activities on Product Performance}, volume={30}, ISSN={["1540-5885"]}, DOI={10.1111/jpim.12065}, abstractNote={This paper describes and tests a model of the impact of front‐end innovation activities on product performance. Data were collected from 272 companies to test the hypothesis that front‐end performance impacts new product performance in the marketplace while controlling for new product development (NPD) processes and strategy. The data support the hypothesis that front‐end performance favorably and independently impacts overall product success, time to market, market penetration, and financial performance.Front‐end performance is predicted by a set of activities, including: the actual amount of front‐end work done in various areas, specifically marketing, R&D, and concept development; the existence of a front‐end process; the existence of a champion; and agreement on the order of developmental steps in the front end. Front‐end activities are related to front‐end performance, and front‐end performance is related to NPD performance. This relationship highlights the distinction between front‐end activities and standard product development practices and the importance of building competency in the front end.This is the first study that quantifies both the nature and amount of work done in the front end and relates that work to commercial performance. This research empirically demonstrates the distinction between the front‐end and formal stages and gates types of systems. This suggests that the concept of the front end needs it own set of theoretical constructs to adequately describe and predict this categorically different set of activities. While this study demonstrates the difference between front‐end and stage‐gate systems, it does not establish the limits of those activities.From a managerial point of view recognizing that formal development and front‐end activities are different mandates that these activities must be managed differently. In particular, the skills, structures, processes, governance, leadership, performance metrics, and resources must be assessed separately and differently. These findings suggest that firms should actively manage the flow of ideas from the front end into the more formal development programs.}, journal={JOURNAL OF PRODUCT INNOVATION MANAGEMENT}, author={Markham, Stephen K.}, year={2013}, month={Dec}, pages={77–92} } @article{castellion_markham_2013, title={Perspective: New Product Failure Rates: Influence of Argumentum ad Populum and Self-Interest}, volume={30}, ISSN={["0737-6782"]}, DOI={10.1111/j.1540-5885.2012.01009.x}, abstractNote={A persistent myth in product innovation and management is that the failure rate of new products is 80% or higher.

The Valley of Death is used as a metaphor to describe the relative lack of resources and expertise in this area of development. The metaphor suggests that there are relative more resources on one side of the valley in the form of research expertise and on the other side by commercialization expertise and resources. Within this valley a set of interlocking roles are examined that move projects from one side to the other. The empirical methodology used in this study gathered data from 272 Product Development & Management Association (PDMA) members with extensive experience in the front end of product development using a Web-based survey instrument. Extensive pretests with experienced practitioners were conducted to develop the instrument. Results indicate that significant development takes place before projects enter into a firm's formal product development process. The data also support the roles of champion, sponsor, and gatekeeper as major actors that work together to develop and promote projects for introduction into the formal process. Champions make the organization aware of opportunities by conceptualizing the idea and preparing business cases. Sponsors support the development of promising ideas by providing resources to demonstrate the project's viability. Gatekeepers set criteria and make acceptance decisions. The data also reveal a dynamic interdependence between role players. It is concluded that the Valley of Death is a productive tool for identifying and understanding a critical area of development that has not been adequately addressed. This research finds a dynamic interplay between roles to accomplish tasks that are not well understood in practice or the literature. The implications of this research are far-ranging. It suggests that companies must understand the challenges in the valley, must develop the skills, and must make resources available to master the front end of product innovation. Recognizing roles, providing resources, and establishing expectations and accountability in this area of development become manageable in light of these results. Theoretically, this research informs role theory of a dynamic set of relationships previously treated as static. It also empirically investigates an area of product development where there is limited data.

Crude oil and gas customers demand sustained low-cost supply. This drives the international oil companies (IOCs) continually to reinvent their businesses in order to sustain them in response to competitive pressures on access to resources, operating cost and capital efficiency. BP is one of the largest IOCs and has been in the vanguard of the industry's transformation from relatively simple geological structures on-shore, to continental shelf off-shore development, to arctic and deep water developments, involving highly complex geological systems and new, massively complex, computer controlled, mechanical structures and equipment. The technology underpinning this transformation includes innovation in drilling, seismic acquisition and interpretation, numerical simulation of reservoir performance, engineering materials for extreme temperatures and pressures, deep water robotic vehicles, and many others. Together, these advances have transformed the industry within the last 30 years, and the pace of change is accelerating. As with other industries, BP's oil and gas production business segment strives to sustain and improve its competitiveness through innovation, both to improve its existing operations and to create new opportunities. As part of this, the Engineering and Production Technology group ("EPT") introduced an innovation process in 2000 that is ongoing into 2007. Given that industry innovation initiatives often fail to persist more that 2 or 3 years, it is instructive to inquire into what underpins the endurance of the EPT Innovation process and what has been learned from it. In this article, we summarize how we manage the innovation process and share what we have learned as a series of lessons. Establishing the Innovation Board In order to prosecute this agenda, an "Innovation Board" was formed and tasked with delivering innovative results in the areas of: 1) business transformation, 2) top-line revenue growth, 2) cost reductions, and 3) health, safety and environment. The Innovation Board started as a result of top management challenging the company for internal, organic growth. The technology group recognized they possessed many technologies which, if developed and utilized, could be valuable in all the areas listed above. The EPT vice president set up a fund to provide the methods, funding and-most critically-allocate time to develop those ideas into growth. The methods and funding to provide individuals the opportunity to innovate is called "creating space." Innovators can now bill their time to the Board for approved projects so they can justify their time spent on innovation. The Board continues to report to EPT senior management and is allocated funding in order to support the internal costs and associated external expenditure. The Board seeks innovative ideas from any member of EPT and then provides support to develop the project to the point where it represents enough value for development by the formal RD these have proved to be a key factor in the durability of the Innovation process, namely: * Membership is by personal invitation of the EPT vice president (under appropriate advisement). This ensures that membership is recognized as a significant opportunity within overall career development. * Membership rotates, such that new members cycle onto the Board and "retire" as their career circumstances evolve. This leads to a continuous refreshing of Board membership, and hence, personal energy and ideas. * Membership is managed to ensure representation of the geographical spread of EPT, the mix of technical disciplines and mix of cultural background, gender and experience. …}, number={3}, journal={RESEARCH-TECHNOLOGY MANAGEMENT}, author={Brown, Chris and Markham, Stephen}, year={2007}, pages={9–14} } @misc{markham_2007, title={Reinventing project management: The diamond approach to successful growth and innovation}, volume={50}, number={6}, journal={Research Technology Management}, author={Markham, S.

Stephen K. Markham addresses this knowledge gap in a study that examines how champions influence other people and what effects champions have on projects and the people those projects involve. The study uses responses from 53 champions of innovation projects in four large firms as well as team members from those projects. Rather than look at the champions' work on project tasks, the study focuses on the influence champions have on other people to support their projects. The results of the study only partially support the idea that champions affect projects by influencing people. In the four firms studied, champions use cooperative rather than confrontative tactics to influence other people. However, the champions' choice of influence tactics does not affect the level of compliance or the willingness to participate in the project that those people demonstrate. On the other hand, the champions appear to have a strong influence on their target's behavior if the champions enjoy positive personal relationships with those people. In general, the tactics used by the champions do not seem to play an important role in the projects studied. From the perspective of the team members, the results of this study do not support the notion that champions make a positive contribution to project performance.

The role of the champion has taken on almost mythic proportions, through oft‐told tales of the development of such disparate products as instant cameras, automobiles, and microprocessors. Notwithstanding the purportedly essential role that champions play, however, we have only anecdotal evidence of the manner in which effective champions operate and the benefits that they offer.Stephen K. Markham and Abbie Griffin suggest that before we can explore questions about how champions affect product development performance, we must address an even more fundamental issue: whether champions actually influence performance. Using data from the 1995 PDMA study of best practices in product development, they test various widely held assumptions about champions and NDP performance. Specifically, they investigate the association between championing and the following variables: NPD performance at the program, firm, and project levels; industry characteristics; and project‐ and firm‐related NPD characteristics.In several respects, the results of their study run counter to current beliefs about product development champions. For example, the study suggests that champions are just as likely to be found in large firms as they are in small firms. Similarly, the results indicate that the likelihood of finding a champion does not differ significantly between technology‐driven firms and marketing‐driven firms. For the firms in this study, champions are no more likely to support radical innovations than they are to back incremental innovations or product line extensions.The results of the study suggest that champions do not directly affect firm‐level NPD performance. Instead, the results of this study associate increased championing with higher levels of NPD program performance, which positively affects firm‐level performance.
