Product tactics in a complex and turbulent environment viewed through a complexity lens

Mason, Roger Bruce January 2012 (has links)
This paper is based on the proposition that the choice of different product tactics is influenced by the nature of the firm’s external environment. It illustrates the type of product activities suggested for a complex and turbulent environment, when viewing the environment through a chaos and complexity theory lens. A qualitative, case method, using depth interviews,investigated the product activities in two companies to identify the product activities adopted in a more successful, versus a less successful, firm in a complex/turbulent environment. The results showed that the more successful company uses some destabilizing product activities but also partially uses stabilizing product activities. These findings are of benefit to marketers as they emphasize a new way to consider future product activities in their firms. Since businesses and markets are complex adaptive systems, using complexity theory to understand how to cope in complex, turbulent environments is necessary, but has not been widely researched, with even less emphasis on individual components of the marketing mix.

Comparing chaos and complexity : the quest for knowledge

Greybe, Sylvia Elizabeth 03 1900 (has links)
Thesis (MA)--University of Stellenbosch, 2004. / ENGLISH ABSTRACT: The question of what it means to say one knows something, or has knowledge of something, triggered an epistemological study after the nature of knowledge and its acquisition. There are many different ways in which one can go about acquiring knowledge, manydifferent frameworks that one can use to search after truth. Because most real systems about which one could desire knowledge (organic, social, economic etc.) are non-linear, an understanding of non-linear systems is important for the process of acquiring knowledge. Knowledge exhibits the characteristics of a dynamic, adaptive system, and as such could be approached via a dynamic theory of adaptive systems. Therefore, chaos theory and complexity theory are two theoretical (non-linear) frameworks that can facilitate the knowledge acquisition process. As a modernist instrument for acquiring knowledge, chaos theory provides one with deterministic rules that make mathematical understanding of non-linear phenomenaa bit easier, but it is limited in that it can only provide one with certain knowledge up until the (system's) next bifurcation (i.e. when chaos sets in). After this, it is near impossible to predict what a chaotic system will do. Complexity theory, as a postmodern tool for knowledge acquisition, gives one insight into the dynamic, self-organising nature of the non-linear systems around one. By analysing the global stability complex systems produce during punctuated equilibrium, one can learn much about how these systems adapt, evolve and survive. Complexity and chaos, therefore, together can provide one with a useful framework for understanding the nature and workings of non-linear systems. However, it should be remembered that every observer of knowledge does so out of his/her own personal framework of beliefs, circumstances and history, and that knowledge therefore can never be 100 percent objective. Knowledge and truth can never be entirely relative either, however, for this would mean that all knowledge (and thereby all opposing claims and statements) is equally correct or true. This is clearly not possible. What is possible, though, is the fulfilling and successful pursuit of knowledge for the sake of the journey of learning and understandi ng. / AFRIKAANSE OPSOMMING: Die vraag na wat dit eintlik beteken om te sê mens weet iets, of dra kennis van iets, het na 'n epistemologiese soeke na die wese van kennis en die verwerwing daarvan toe gelei. Daar is baie maniere waarop mens kennis kan verwerf, baie verskillende raamwerke wat mens kan gebruik om te soek na waarheid. Omdat die meeste wesenlike stelsels waarvan mens kennis sou wou verkry (organies, sosiaal, ekonomies ens.) nie-lineêr is, is 'n verstaan van nie-lineêre stelsels belangrik vir die kennisverwerwingsproses. Kennis vertoon die eienskappe van I n dinamiese, aanpassende stelsel, en kan dus via 'n dinamiese teorie van aanpassendestelsels benader word. Daarom is chaosteorie en kompleksiteitsteorie twee teoretiese (nie-lineêre) raamwerke wat die proses van kennisverwerwing kan vergemaklik. As I n modernistiese instrument vir kennisverwerwing, verskaf chaosteorie deterministiese reëls wat die wiskundige verstaan van nie-lineêre verskynsels bietjie vergemaklik, maar dit is beperk deurdat dit net sekere kennis tot op die (stelsel se) volgende splitsing (d.w.s. waar chaos begin) verskaf. Hierna, word dit naasonmoontlik om te voorspel wat I n chaotiese stelsel gaandoen. Kompleksiteitsteorie, as I n postmodernistiese gereedskap vir kennisverwerwing, gee mens insig in die dinamiese, selforganiserende aard van die nie-lineêre stelsels om mens. Deur die globale stabiliteit wat komplekse stelsels gedurende onderbreekte ewewig ("punctuated equi/ibrium"}toon te analiseer, kan mens baie leer van hoe hierdie stelsels aanpas, ontwikkel en oorleef. Kompleksiteit en chaos, saam, kan mens dus van a nuttige raamwerk vir die verstaan van die wese en werkinge van nie-lineêre stelsels, voorsien. Daar moet egter onthou word dat elke waarnemer van kennis dit doen uit sy/haar persoonlike raamwerk van oortuiginge, omstandighede en geskiedenis, en dat kennis dus nooit 100 persent objektief kan wees nie. Kennis en waarheid kan egter ook nooit heeltemaal relatief wees nie, want dit sou beteken dat alle kennis (en hiermee ook alle teenstrydige aansprake en stellings) gelyk korrek of waar is. Hierdie is duidelik onmoontlik. Wat wel moontlik is, is die vervullende en suksesvolle strewe na kennis ter wille van die reis van leer en verstaan.

Empirical investigation into the use of complexity levels in marketing segmentation and the categorisation of new automotive products

Taylor-West, Paul January 2013 (has links)
This thesis is set in the context of the automotive industry where launches of new products with high levels of technical innovations are becoming increasingly complex for consumers to comprehend. Car manufacturers need to understand consumer perceptions of new models so they can categorise their products form the consumer perspective, to obtain a more accurate indication as to where their products fit within the increasingly defined consumer segments. Situational and personal variables now play the most important roles in marketing. In the area of nested segmentation consumer variables are only concerned with their needs, attitudes, motivations and perceptions and overlook any previous experience, exposure or familiarity that a consumer may or may not have had with the product. It is argued here that consumers have differing perceptions of newness and that asking how new and new to whom would be valid questions for marketers when introducing new products. If car manufacturers can categorise their products in terms of newness for specific consumers based on their levels of Expertise, Involvement and Familiarity with the product, manufacturers will be able to target appropriate markets more effectively. To explore this area a mixed methods research approach was applied. This research found that the level of Involvement with the product, from a motivational aspect, gave rise to different levels of interest and enthusiasm between consumers and has a direct impact on how different types of consumers view new products. In addition the differing levels of consumer knowledge highlights the need to improve targeting of marketing communications so that manufacturers provide a better understanding of complex new products to consumers. Current mass marketing methods based on consumer demographics are no longer sufficient. This research found that a consumer s level of Expertise, Involvement and Familiarity (EIF) with a specific product can be captured using a multi-dimensional scale to measure consumer product knowledge and provide an accurate consumer segmentation tool. By offering different explanations of product innovations to these consumer segments, according to a customer's EIF, marketers will achieve more effective targeting, reduce marketing costs and increase marketing campaign response.

Methods of computing in a ubiquitous age

Yeh, Wei Cheng, 1975- 17 September 2010 (has links)
As technology becomes integrated into everyday life, the relationship between the human and machine must be kept in a balance. Not only does the technology have to perform its intended function, but it must do so in accordance with the dynamic parameters of the complex use environment, in a way that does not encumber the user either physically or mentally. The dissertation explores the challenges of such a scenario through an analysis of three core facets: Affordances, or the user interface cues that allow an intuitive means of operating a device; the aspect of simplicity and its effect on the use factors of the technology (while something might seem to be simple, it may actually be complex to use); and cognitive load in terms of user impact, as a result of utilizing the technology. These illustrate the challenges inherent in understanding the facets fundamental to human- machine interaction in a complex environment. The three factors will be explored first through an historical analysis of the work in each aspect. The theories at hand will be utilized to inform the creation of iterative generations of wearable sensory systems. By utilizing the systems in the field of dance, the theoretical aspects of the core factors can be gauged by actual implementation. Each implementation will be compared side by side to gauge differences in terms of movement dynamics and efficacy of execution. The study will reveal that the three core factors of affordance, simplicity and cognitive load combine synergistically to create a foundational methodology for seamless integration of technology in a complex use scenario. Furthermore, the facets of interoperability between devices in a complex use environment will be illustrated through the theory of intra-interactivity. Finally, the dissertation will illustrate the advantages of passive user interaction and its necessity in relation to the factor of cognitive load. / text

Marketing Your Intangible Future : Tangibilization of Retirement Savings at Handelsbanken and Swedbank

Larsson, Emelie, Södersten, Marianne January 2008 (has links)
<p>The purpose of this study is to investigate how individual retirement savings are made tangible for potential customers. As case companies we have studied the marketing strategies of Handelsbanken and Swedbank.</p><p>We use Miller and Foust’s classification of services by intangibility based on attributes and benefits and Tarn’s four strategy marketing-based model in order to find out how the retirement savings are made tangible.</p><p>We find that the attributes and benefits that are used to define retirement savings depend on how the service is affiliated to life-insurance or banking services. Intangibility is coped by simplifying the products by lifting forward salient features. Complexity is overcome by explanation. Putting emphasis on flexibility is a mean to cope with the uncertainty of future income.</p>

Coloration et convexité dans les graphes

Araujo, Julio 13 September 2012 (has links) (PDF)
Dans cette thèse, nous étudions plusieurs problèmes de théorie des graphes concernant la coloration et la convexité des graphes. La plupart des résultats gurant ici sont liés à la complexité de calcul de ces problèmes pour certaines classes de graphes. Dans la première, et principale, partie de cette thèse, nous traitons de coloration des graphes qui est l'un des domaines les plus étudiés de théorie des graphes. Nous considérons d'abord trois problèmes de coloration appelés coloration gloutone, coloration pondérée et coloration pondérée impropre. Ensuite, nous traitons un probl ème de décision, appelé bon étiquetage de arêtes, dont la dé nition a été motivée par le problème d'affectation de longueurs d'onde dans les réseaux optiques. La deuxième partie de cette thèse est consacrée à un paramètre d'optimisation des graphes appelé le nombre enveloppe (géodésique). La dé nition de ce paramètre est motivée par une extension aux graphes des notions d'ensembles et d'enveloppes convexes dans l'espace Euclidien. En n, nous présentons dans l'annexe d'autres travaux développées au cours de cette thèse, l'un sur les hypergraphes orientés Eulériens et Hamiltoniens et l'autre concernant les systèmes de stockage distribués.

Chronic Pain Management in a Reservation Border Town

Farrell, Cynthia S. January 2010 (has links)
Pain is a growing national public health problem that contributes to spiraling health care costs and significant societal burden in the United States. It is the most common reason for seeking health care services, and is the leading cause of disability (CDC, 2008). Inadequately treated pain has profound social, psychological, economic, and physiological consequences for patients, their families, and society (American Pain Society, 2009).A community-based participatory research (CBPR) approach was used for this project to develop a knowledge base about issues associated with chronic pain and its treatment among Native American people in Winslow, AZ. Mixed methods (qualitative and quantitative) were used to gain insight into the local factors that contribute to the self-management and treatment of chronic pain.The results of a provider survey indicated that there are negative psychological traits toward patients with chronic pain such as authoritarianism, intolerance of ambiguity, reliance on technology, and locus of control which are factors that are known to negatively influence pain care (Weinstein et al, 2000). Lack of knowledge regarding pain and pain management along with perceptions and fears related to drug regulatory agencies were additional factors that were found, constituting additional barriers. Patient participants were generally dissatisfied with the pain care practices at Winslow Indian Health. Patient reported treatment goals that included relief of pain, improved quality of life, the ability to return to work, the ability to perform household chores, and the ability to participate in more physical leisure activities.This results of this practice inquiry indicate there is a disconnect between patient and provider views and expectations around pain treatment and the need for further studies to determine the best ways to address chronic pain at the local level. The development of a pain management program is recommended to address the unmet needs of patients with chronic pain. Education in pain management is recommended for healthcare providers, including information regarding the benefits of non-pharmacologic therapies for pain management. The practice inquiry also supports the need for new policies at the local, tribal, and national levels to address pain as a growing public health issue.

A Statistical Analysis of Bubble Sort in terms of Serial and Parallel Computation

Panigrahi, Sunil Kumar, Chakraborty, Soubhik, Mishra, Jibitesh 15 February 2012 (has links)
In some recent papers, the weight based statistical bounds have arguably explained time complexity better than the count based mathematical bounds. This is definitely true for average case where for an arbitrary code it is difficult to identify the pivotal operation or pivotal region in the code for taking the expectation and/or when the probability distribution, over which expectation is taken, becomes unrealistic over the problem domain. In worst case, it can certify whether a mathematical bound is conservative or not. Here we revisit the results on Bubble sort in sequential mode and make an independent study of the same algorithm in parallel mode using statistical bound

Does high product complexity &amp; production cost drive high customer involvement in product development?

Wendel, Ellen January 2009 (has links)
Does high products complexity &amp; production cost drive high customer involvement in product development? Author: Ellen Wendel Tutor/Examiner: Sarah Philipson   Background   The purpose of this thesis first arose when interviewing the CEO and the chief of product development of a Swedish wood company. The lack of communication between the two of them and the overall information flow within the company seemed to me brutally bad. When leaving that company a question popped up: Do a low production cost/unit and/or a low product complexity on an industrial market result in low customer involvement?   Problem focus/hypotheses   Product failure is costly and time consuming; doing it right the first time can keep a company alive and give it competitive advantages, Matzler et al (1997). Customer involvement has proven to increase the chances for a successful product launch, von Hippel (1988), Lagrosen (2005), Pitta et al (1996) and Matzler et al (1997). With the assumption that customer involvement can affect product development in a positive way, any conditions that might drive customer involvement in product development would be of interest. This thesis investigates three hypotheses concerning how product complexity and production cost drive customers involvement; H1: High product complexity positively predicts the use of high customer involvement in the product development. H2: High production cost positively predicts the use of high customer involvement in the product development. H3: High production cost and high product complexity together positively predicts the use of high customer involvement.   Method   The main study was executed with surveys sent per e-mail. The investigated populations are wood component suppliers and machine suppliers. The suppliers were chosen to get a vast range of product complexity and production cost. The hypotheses were analyzed with chi-square statistics and percentages.   To get a basic understanding of the industry, I first made a pre-study; interviewing two suppliers and telephone interviewing the head of glued edge pine panel issues at the Swedish Wood &amp; Furniture Association.   Findings   Hypothesis 1 I conclude that higher product complexity leads to higher customer involvement on both industries. This result gives more validation to the emerging theory stated by Richard et al (2004). Hypothesis 2  This thesis validates hypothesis 2 among wood suppliers. I suggest future research to validate a possible theory the states that higher production cost drive higher customer involvement. Hypothesis 2 is not accepted on the machine supplier industry since the results were inconclusive. No overall pattern was found.  However, the result indicates that the hypothesis might be correct up until a certain level of complexity, after which the relationship is negative. Hypothesis 3   I consider hypothesis 2 to be validated on the wood supplier market. I suggest future research to validate a possible theory the states that higher production cost and product complexity and production cost combined drive higher customer involvement. The thesis result indicates that hypothesis 3, on the machine supplier market, might be correct up until a certain level of complexity and production cost combination, after which the relationship is negative. Hypothesis 3 cannot be accepted for the machine supplier industry since the results are inconclusive. General findings from the hypotheses All three hypotheses indicate a positive prediction that product complexity, production cost and the two variables combined will drive the behavior of “usage or no usage” of customer involvement, regardless of industry. / <p>Opponenter: Elna Hägglund och Frida Tillmar</p>

Understanding and Improving Undergraduate Engineering Education

Foster, Jason January 2001 (has links)
This thesis seeks to understand the past and present state of engineering education and to plot a course for its future evolution. This research is limited to engineering education as it has taken place in North American universities during the last half of the 20th century. Within this context, broad trends are described. The description is supplemented with a case study of a unique and innovative engineering programme. The trends and case study form the foundation of a synthesis, and alternative vision, for higher education and engineering education. The intended audience of this thesis includes those who teach, design curriculum, or administer engineering education programmes. The description of the current state of engineering education contains analyses of the state and of the gaps within it. Both of these analyses are based almost exclusively on publicly available documentation. The present state of engineering is drawn from accreditation criteria. Critiques of the current state and suggestions for future change are drawn from reports commissioned by groups affiliated with professional engineering. The discussions identify recurring themes and patterns. Unlike the analysis of the literature, the case study merges interview evidence and personal experience with the available documentation. The synthesis and visions continue the trend away from formal sources towards experiences and beliefs. Engineering education research is in its infancy and shows few signs of maturing. There is no documented, common framing of engineering education nor have there been any efforts in this regard. Few sources address broad issues and those that do lack theoretical rigour. The visions for engineering education are simple amalgams of visions for the profession and for general higher education. The Department of Systems Design Engineering has enjoyed great past successes because of its unique vision that combines the theories of systems, complexity, and design with the discipline of engineering. Its recent decay can be traced to its faculty having collectively lost this vision. The original vision for Systems Design Engineering holds promise as a means to reinvent and reinvigorate both the engineering profession and engineering education. For this renaissance to be successful a theoretically rigorous research programme assessing the past, present, and future of engineering and engineering education must be developed.
