The management of complexity in project management – a qualitative and quantitative case study of certified project managers in Germany

With the increased globalization and expansion of the markets worldwide, companies have to struggle with increased competition. Therefore, organisations have begun to offer advantages such as a personalisation of products to potential customers. Market conditions and legal policies can make it challenging to predict whether those ad-vantages can be realized. Project managers are often in the position of having to fulfil these requirements; in continuously changing influencing factors that make tasks diffi-cult to manage. These circumstances create complexity. Frequently, managers are una-ware that complexity has created problems in a specific project. Often, the traditional standards of project management no longer provide a sufficient support to managers of complex projects. This research investigates how current standards of project management address com-plexity, and whether a supplement is necessary. Complexity strengtheners are investi-gated. One standard Project Management Institute (PMI) is selected as an example to analyze the influence of strengtheners on PM-processes. A funnel model is developed based on these research findings. This is aimed to help managers in their daily practice and support them in categorizing the complexity of their projects. Based on this model, managers should be able to recognize the actual strengtheners of complexity and which processes of their project are affected. Finally, a possible adaption of the standard is re-searched. A proposition for a new comprehensive guide is designed to support manag-ers carrying out complex projects. The key managerial implication of this research is the development of a five-step model for handling complexity in projects: forming, storming, norming, performing, and ad-journing. Furthermore, the intent of this thesis is to make a valid contribution to the management literature. For handling complexity the new funnel model should close the gap between the recognition of complexity in a project and underlying causes. The new five-step model thus provides project managers helpful guidelines for handling complex projects. This research applies a mixed method, consisting of a survey (quantitative method) and focus interviews (qualitative method) with experts of project management (PMI) in Germany. There are approximately 4.900 PMI certified project managers in Germany; more than 170 participated in the survey (3.6%). This is considered sufficient to provide reliable results for this research. Further, three focus interviews deepen the knowledge and validate the results of the survey: Complexity is an actual problem in project man-agement. Existing standards are sufficient for project management, but complexity can-not be standardized. This thesis proposes to help project managers to resolve project complexity by providing guidelines for navigating through complex projects

Electrocortical evidence for long-term incidental spatial learning through modified navigation instructions

© Springer Nature Switzerland AG 2018. The use of Navigation Assistance Systems for spatial orienting has become increasingly popular. Such automated navigation support, however, comes with a reduced processing of the surrounding environment and often with a decline of spatial orienting ability. To prevent such deskilling and to support spatial learning, the present study investigated incidental spatial learning by comparing standard navigation instructions with two modified navigation instruction conditions. The first modified instruction condition highlighted landmarks and provided additional redundant information regarding the landmark (contrast condition), while the second highlighted landmarks and included information of personal interest to the participant (personal-reference condition). Participants’ spatial knowledge of the previously unknown virtual city was tested three weeks later. Behavioral and electroencephalographic (EEG) data demonstrated enhanced spatial memory performance for participants in the modified navigation instruction conditions without further differentiating between modified instructions. Recognition performance of landmarks was better and the late positive complex of the event-related potential (ERP) revealed amplitude differences reflecting an increased amount of recollected information for modified navigation instructions. The results indicate a significant long-term spatial learning effect when landmarks are highlighted during navigation instructions

Models of anagram solution

It is generally accepted that anagrams are solved by means of an interrogation of the lexicon on the basis of an orthographically regular subsequence of the letters given. This study was concerned with the effect upon the solution process of providing the semantic category that contained the solution. In this situation, the instance dominance of the solution in the specified category affected the solution time for anagrams drawn from small categories, but the number of letters in the anagrams did not. For anagrams drawn from large categories, the reverse was true. Moreover, cuing with the appropriate taxonomic category produced a significant reduction in solution time in the case of items from small categories, but not in the case of items from large categories. It is concluded that subjects employ a semantically directed interrogation of the lexicon when they are cued with a small category, but a structurally directed interrogation of the lexicon otherwise
