Decision-making in everyday life has an essential role in effectively completing personal tasks and processes. The complexity of these processes and the resulting cognitive load of managing them may vary significantly. To decrease the cognitive load created by such decision-making efforts and to obtain better outcomes, recommendation systems carry significant potential. In order to investigate the benefits provided by decision support systems (DSS) in personal process management (PPM), we first build a constraint programming (CP) model and a prototype context-aware-mobile application employing this CP model. Then, we evaluate the application and the model via two exemplary real-world scenarios. The scenarios form the core of the experiments conducted with 50 participants. We compare the participants’ planning performances with and without the PPM system with quantitative metrics such as planning times and scenario objective values. In addition, System Usability Scale (SUS) questionnaires and open-ended questions provide qualitative evaluation results. Throughout the study, we apply the Design Science Research methodology to rigorously conduct research activities by proof of concept, proof of use, and proof of value. The empirical results clearly show that our proposed model for PPM is effective, and the developed prototype solution generates positive participant comments as well as a high SUS score. Overall, the prototype PPM system with CP implementation leads to better planning in less time in the planning phase, and it lets the user do fast replanning in the execution phase, which is invaluable in dynamically changing situations such as daily activities.

A reference model for personal process management (PPM) Systems Oruc, Sercan; Eren, Pekin Erhan; Koçyiğit, Altan (2019-06-01) Decision making in everyday life is one of the key activities that has significant effect in shaping the flow of living, the quality of life, and the effectiveness of completing daily life tasks. Recommendation systems are widespread, being used via various mediums to decrease the cognitive load of these decision-making activities. Personal process management (PPM) is the management of “flow of activities” (processes) in people's personal lives. These processes and their management may have small but also e...
A Case Study of Informal Online Community for Graduate Students: A Community of Practice Design Doğan, Sibel; Caner, Sonay; İşgör Şimşek, Esra (null; 2016-11-01) Being in academic world needs continuous development of oneself and dedicated working. While starting this journey, one definitely needs support and guidance from other experienced academicians. If you are working as a research assistant in a university probably you are luckier than people who are just graduate students or working outside of the university. As a research assistant you can have opportunity of having good relationships with academicians and getting help when you need. However, people who work...
An integrative model of job characteristics, job satisfaction, organizational commitment, and organizational citizenship behavior Ünüvar, Tahir Gökhan; Acar, Feride Pınar; Department of Business Administration (2006) Existing literature indicates that job characteristics, job satisfaction, organizational commitment, and organizational citizenship behavior are very important for effective organizational functioning. Previous research on citizenship behaviors made limited contribution to the literature, since it ignored the relationships between job characteristics and citizenship behaviors together with the influences of job satisfaction and organizational commitment. The present study attempted to test a new integrative...
An integrative model of transformational leadership, organizational commitment, job satisfaction and organizational citizenship behavior Küçükbayrak, Ruken; Acar, Feride Pınar; Department of Business Administration (2010) Existing literature indicates that transformational leadership, job satisfaction, organizational commitment, and organizational citizenship behavior are very important for effective organizational functioning. Previous research on citizenship behaviors made limited contribution to the literature, since it mainly did not consider the relationships between transformational leadership and organizational citizenship behaviors together with the influences of job satisfaction and organizational commitment. This s...
A Comparison of telecommuting and workplace employees in terms of situational strength, personality, work attitudes and performance Girit, Dilara; Bilgiç, Reyhan; Toker, Yonca; Department of Psychology (2013) The purpose of the present study is to examine the personality, work attitudes, and performance differences of employees working in different work arrangements, (home and office-based work contexts). The variables used were situational strength (clarity, consistency, and constraints), and personality (conscientiousness and extraversion). Job satisfaction, organizational commitment, and turnover intentions, and job performance were the work outcome variables. 359 employees working at offices, and 261 employe...
