The dominant design concept describes the evolution from one dominant design to a new one, or in a new industry, the evolution to a set of standards and features that becomes a dominant design for that particular product or sector. Typically the dominant design is used to describe industry trends. This thesis takes the bottom up perspective, i.e. the company's perspective, to identify if, or what parts, of the dominant design model that can be used as an explanatory tool of innovation in the two ERP companies chosen. This thesis has found that some parts of the dominant design model can be used to describe innovation in our two case companies. However, the model has to be altered to fit the particular needs of the software industry and exclude the concept of process innovation, which is a part of the original dominant design model. By considering a company’s existing situation, e.g. customers, market share, partnerships etc. and fitting these facts into our altered dominant design model it should be possible to explain actions undertaken by an ERP company.

Companies are more and more moving to low wage regions like Eastern Europe and Asia to stay competitive. Instead of lowering the cost of production, it has been argued that a company can stay competitive through making the use of the resources more efficient. In this study the effects a German resource saving concept, involving reorganization towards processes and an Advanced Planning and Scheduling (APS) module, has on Supply Chain Management (SCM) are investigated. In addition to this a comparison between German best-practice companies and Swedish companies has been done. This comparison was conducted in order to determine the changes needed to be made when taking this German concept to Swedish companies. The results of this study indicate that through the German resource saving concept major improvements in delivery performance, responsiveness, supply chain costs, and asset management can be achieved. Further, this study has shown that there are very good possibilities for Swedish companies at reaching these improvements successfully. Barriers to a success in Sweden include a lack of managerial commitment and hierarchies as well as outsourced IT departments at Swedish companies. Recommendations to overcome these barriers consist of training key users more thoroughly and stressing the importance of committed managers.

One of the major advancements in the IT industry during the 1990s was the development of Enterprise Resource Planning (ERP) systems. Beyond the high costs and significant amount of effort needed to implement such a system, the possible benefits for the organization in achieving more efficient operations and improving its competitive stance in the competitive business environment have been undoubted. The high failure rates of ERP systems implementations (Soh et al., 2000; Willis and Willis-Brown; 2002) have paved the way for a chase from both academicians and practitioners to understand and pinpoint the critical success factors that positively impact this type of projects’ success. Research has been done for ERP implementations in numerous environments but there is a serious gap in the literature regarding implementations in the Cypriot context. Furthermore, after the island’s accession to the European Union (EU) in 2004, the need for the governmental sector to harmonize its systems and processes according to EU directives and to provide efficient services through transparent processes to citizens of Cyprus urged public organizations to proceed with the adoption of ERP systems to serve these purposes from both technological and business aspects. This thesis aims to investigate the critical success factors that foster the successful rollout of ERP implementation projects in Cypriot public sector organizations. From the literature review a research proposition is devised through the development of a theoretical framework consisting of 10 critical success factors. These factors are examined in the specific project environment and their applicability and impact in successful implementations is determined. A qualitative approach has been followed, through a multiple-case study in three Cypriot public sector organizations, by conducting a set of 9 semi-structured interviews and analyzing the results to determine the theoretical framework’s fit in the particular context and furthermore to determine the criteria which are used to determine ERP implementation success in the specific projects. The results of the study indicate that project success is evaluated solely based on three criteria; time, cost and quality. In addition, 9 out of the 10 factors of the theoretical framework appear to be critical for implementation success.

While it is known that primitive, low-level visual stimuli such as abrupt visual onsets or luminance changes can bias attentional orienting without willful intent on the part of the observer, comparatively little is known about how attention functions in rich, dynamic, meaningful contexts, such as those that comprise our everyday lives. The primary motivating hypothesis of this investigation is that, given our intrinsic needs as evolved social organisms, as well as our capability for behavioral flexibility, the attention system should be sensitive not only to low-level stimulus features, but also to complex stimuli that provide behaviorally relevant information. Three separate lines of research will be presented, each one providing a unique perspective on this issue. The first examined attentional orienting to socially relevant stimuli, finding that eye gaze serves as particularly potent cue for attentional orienting, driving the cortical orienting network more robustly than non-social stimuli, and resulting in a larger attention-related modulation of the early visual processing of stimuli appearing at attended locations. The second line of inquiry investigated patterns of eye movements while participants viewed naturalistic navigational scenes, revealing a dynamic interplay of orienting to the various behaviorally relevant aspects of the scene. The third set of studies specifically addressed whether, given the relevance of heading information for guiding navigational behavior, there is evidence that attention can be oriented automatically to the heading point in an optic flow field simulating the patterns of visual stimulation that accompany self-motion. Together, the results converge on the conclusion that attention can be oriented automatically in a dynamic, flexible, and continuous manner on the basis of complex visual stimuli that provide behaviorally relevant information.

The major objective of present study is to find out the sources which cause higher Work in Process (WIP) in the production line. In which a detailed analysis is performed in the area of inventory, reorder point, Takt time, and Kanban. All the analyses are based on the data obtained from the company’s ERP system and have been used to run some scenarios during the analysis.Lots of problems are responsible to cause higher WIP. But current report only focuses and concentrates in leveling the work load, implementing pull system, suggesting reorder point and Takt time.The current situation is described through Value-stream Map (VSM) and the impact cost matrix is used to show the impact of each problem in the production line in terms of costs. In the analysis chapter, root cause method has been used in order to show the cause and effect of higher WIP. Detailed analyses together with explanations are listed by orders. Therefore, three major suggestions are proposed and the future VSM is plotted to show the effect and change of the suggestions which helps to improve the current situation by eliminating the waste.

I denna uppsats presenterar vi en ny infallsvinkel på hur datatolkning i moderna organisationer bör hanteras, såväl praktiskt som teoretiskt. Studien genomfördes med ett kvalitativt och abduktivt tillvägagångssätt byggt på grounded theory med deltagande observationer och intervjuer med aktörer inom organisationen. Vårt teoretiska ramverk är byggt utifrån Carliles (2002) teorier om semantiska barriärer och påbyggda genom Iveroths (2011) tidigare forskning utifrån common meaning. Således är vårt teoretiska ramverk lämpligt för att tolka hur barriärer som hindrar en synkron datatolkning mellan olika aktörer i organisationer belysts i tidigare litteratur, hur dessa barriärer kan överbryggas samt olika synsätt på kunskapen som ett regelrätt mått.Avsaknad av kunskapskonsensus i organisationer grundar sig i semantiska barriärer för datatolkningen som måste överbryggas med sociala interaktioner. Organisationer går mot kunskapskonsensus genom att utifrån datakällan arbeta med – i) teknologiskt medierade trading zones men även ii) socialt dimensionerade överbryggningsaktiviteter med målet att skapa kunskapskonsensus mellan och inom aktörsgemenskapen.

Certain electrophysiological markers hold promise in distinguishing individuals with major depressive disorder (MDD) and in predicting antidepressant response, thereby assisting with assessment and optimizing treatment, respectively. This thesis examined resting brain activity via electroencephalographic (EEG) recordings, as well as EEG-derived event-related potentials (ERPs) to auditory stimuli and facial expression presentations in individuals with MDD and controls. Additionally, the utility of resting EEG as well as auditory ERPs (AEPs), and the associated loudness-dependence of AEPs (LDAEP) slope, were assessed in predicating outcome to chronic treatment with one of three antidepressant regimens [escitalopram (ESC); bupropion (BUP); ESC+BUP]. Relative to controls, depressed adults had lower pretreatment cortical activity in regions implicated in approach motives/positive processing. Increased anterior cingulate cortex (ACC)-localized theta was observed, possibly reflecting emotion/cognitive regulation disturbances in the disorder. AEPs and LDAEPs, putative indices of serotonin activity (implicated in MDD etiology), were largely unaltered in MDD. Assessment of ERPs to facial expression processing indicated slightly blunted late preconscious perceptual processing of expressions, and prolonged processing of intensely sad faces in MDD. Faces were rated as sadder overall in MDD, indicating a negative processing bias. Treatment responders (vs. non-responders) exhibited baseline cortical hypoactivity; after a week of treatment, cortical arousal emerged in responders. Increased baseline left fronto-cortical activity and early shifts towards this profile were noted in responders (vs. non-responders). Responders exhibited a steep, and non-responders shallow, baseline N1 LDAEP derived from primary auditory cortex activity. P2 LDAEP slopes (primary auditory cortex-derived) increased after a week of treatment in responders and decreased in non-responders. Consistent with overall findings, ESC responders displayed baseline cortical hypoactivity and steep LDAEP-sLORETA slopes (vs. non-responders). BUP responders also exhibited steep baseline slopes and high ACC theta. These results indicate that specific resting brain activity profiles appear to distinguish depressed from non-depressed individuals. Subtle ERP modulations to simple auditory and emotive processing also existed in MDD. Resting alpha power, ACC theta activity and LDAEP slopes predicted antidepressant response in general, but were limited in predicting outcome to a particular treatment, which may be associated with limited sample sizes.

This thesis addresses the computation and organization of conceptual knowledge. Specifically, it focuses on the recruitment of concrete knowledge during single word reading using behavioural and electrophysiological methodologies. Chapters 1 and 2 assess how number of visual semantic features listed by participants as being part of a given concept influence the speed of word meaning computation, and its neural underpinnings, providing evidence for modality-specific neural organization. Chapter 3 assesses the flexibility of knowledge activation as a function of specific task constraints, suggesting a multi-faceted approach to semantic richness is needed. Chapter 4 describes a novel application of recent statistical advances to the analysis of real-time electrophysiological data, and highlights some limitations of standard analytical approaches. Chapter 5 assesses the real-time influence of several types of knowledge on the neuroelectric activity underlying concrete word meaning computation. A timecourse of sensory-based knowledge type activation is outlined. Finally, Chapter 6 describes a novel approach whereby real-time electrophysiological brain activity is used to predict the speed of semantic decision making, providing further evidence of a highly flexible, but finely structured, human semantic memory system.

Companies acquiring ERP systems are often dissatisfied with the project and therefore consultancy firms wish to make use of project models in order to achieve success in implementations. Since research on ERP implementations in service companies is limited, there is a need for mapping of critical activities in implementation projects in this line of business. Under these premises, the purpose of our master thesis is to develop a model for implementation of ERP systems, specified in activities, which can be used by mid-sized consultancy firms with mid-sized qualified service companies as customers. A literature study including project models, modern models and methodologies for ERP implementation, commonly existent activities, success factors and system development methods was carried out. Starting out with this, a theoretical model for ERP implementation was generated. In excess of this, a case study was conducted, where the implementation of the ERP system Microsoft Dynamics AX at the service company Eurostep, performed by the consultancy firm Medius, was studied. A comparative analysis was performed, where the theoretically deduced model of ERP implementation was complemented and revised. The result of the master thesis is a consultancy model with four phases, with related activities, for ERP implementation in service companies. In order to fulfill the needs identified in the study, the model includes the following: - Clear responsibility distribution - Milestones as ending criteria - Suitable ways of work within the phases During the study the need for an anchoring and commitment process, and the need to consider the customer’s features, emerged. This can contribute to consultancy firms getting enough involvement in the project from their customers, which is important in order to achieve desired quality and to finish the project within the given time frame. / Företag som anskaffar affärssystem är ofta missnöjda med projektet och konsultbolag önskar därför använda sig av projektmodeller för att lyckas med införanden. Eftersom forskningen kring affärssysteminföranden i tjänsteföretag är begränsad, finns ett behov av kartläggning av kritiska aktiviteter i införandeprojekt hos denna typ av företag. Mot bakgrund av detta är syftet med vårt examensarbete att utveckla en modell för införande av affärssystem, konkretiserad i aktiviteter, som kan användas av medelstora konsultbolag med medelstora kvalificerade tjänsteföretag som kunder. En litteraturstudie innefattande projektmodeller, moderna modeller och metodiker för affärssystemimplementering, vanligt förekommande aktiviteter, framgångsfaktorer och systemutvecklingsmetoder genomfördes. Med utgångspunkt i denna togs en teoretisk modell för affärssysteminföranden fram. Utöver detta gjordes en fallstudie där implementeringen av affärssystemet Microsoft Dynamics AX hos tjänsteföretaget Eurostep, som genomförs av konsultbolaget Medius, studerades. En komparativ analys genomfördes av det studerade fallet, där den teoretiskt framtagna modellen för affärssysteminförande kompletterades och reviderades. Resultatet av examensarbetet är en konsultmodell med fyra faser, med tillhörande aktiviteter, för affärssysteminförande i tjänsteföretag. För att uppfylla de i studien identifierade kraven inkluderar modellen följande: - Tydlig ansvarsfördelning - Milstolpar i form av avslutskriterier - Lämpligt arbetssätt inom faserna Under studien framkom att en förankrings- och engagemangsprocess behövs, samt att hänsyn behöver tas till kundens egenskaper. Detta för att konsultbolag ska få sina kunder tillräckligt involverade i projektet, vilket är viktigt för att nå önskvärd kvalitet och för att kunna slutföra projektet inom dess givna tidsramar.
