How elephants learn the new dance when headquarters changes the music: Three case studies on innovation strategy change

Does a product innovation strategy change at company headquarters resonate the same way at different strategic business units (SBUs)? What factors play a role in differing implementation of new innovation strategies? A collective case study was conducted at three SBUs of an international conglomerate to investigate why the SBUs implement the same corporate innovation charter in vastly different manners, both in strategic processes and in organizing for new product development (NPD). This study's contribution to the literature is twofold. First, it develops initial insights into how three SBUs implement diverse SBU-level innovation strategies in response to the same product innovation charter. Second, it extends the findings of previous studies on NPD strategy by presenting how three SBUs reshape their structure and resource allocation, changing various dimensions of their innovation strategy while also fitting the competitive structure in their individual, non-high-tech, traditional manufacturing industries as they respond to the corporate mandate. In this study, several factors were observed to influence a firm when formulating a new product innovation strategy. First, past performance and strategic typology constrain the innovation paths available. Poor past performance limits available resources whereas the strategic typology managers use limits their ability to recognize other opportunities. Next, capacity constraints provide a catalyst in moving toward process improvements. Third, management involvement in the day-to-day implementation of change is necessary to ensure that the new processes are implemented. Finally, corporate performance metrics are quite influential in how SBUs adapt to change. This study identifies that even with the immense power corporate has over these SBUs, some still dance to their own tune, ignorant of their deviation from the corporate mandate because the metric is not sufficient to detect these deviations. This study suggests the use of multiple types of metrics to minimize the likelihood of nearsighted responses to innovation charter changes. © 2008 Product Development & Management Association

Host resources and parasite traits interact to determine the optimal combination of host parasite‐mitigation strategies

Organisms have evolved diverse strategies to manage parasite infections. Broadly, hosts may avoid infection by altering behaviour, resist infection by targeting parasites or tolerate infection by repairing associated damage. The effectiveness of a strategy depends on interactions between, for example, resource availability, parasite traits (virulence, life‐history) and the host itself (nutritional status, immunopathology). To understand how these factors shape host parasite‐mitigation strategies, we developed a mathematical model of within‐host, parasite‐immune dynamics in the context of helminth infections. The model incorporated host nutrition and resource allocation to different mechanisms of immune response: larval parasite prevention; adult parasite clearance; damage repair (tolerance). We also considered a non‐immune strategy: avoidance via anorexia, reducing intake of infective stages. Resources not allocated to immune processes promoted host condition, whereas harm due to parasites and immunopathology diminished it. Maximising condition (a proxy for fitness), we determined optimal host investment for each parasite‐mitigation strategy, singly and combined, across different environmental resource levels and parasite trait values. Which strategy was optimal varied with scenario. Tolerance generally performed well, especially with high resources. Success of the different resistance strategies (larval prevention or adult clearance) tracked relative virulence of larval and adult parasites: slowly maturing, highly damaging larvae favoured prevention; rapidly maturing, less harmful larvae favoured clearance. Anorexia was viable only in the short term, due to reduced host nutrition. Combined strategies always outperformed any lone strategy: these were dominated by tolerance, with some investment in resistance.Choice of parasite mitigation strategy has profound consequences for hosts, impacting their condition, survival and reproductive success. We show that the efficacy of different strategies is highly dependent on timescale, parasite traits and resource availability. Models that integrate such factors can inform the collection and interpretation of empirical data, to understand how those drivers interact to shape host immune responses in natural systems
