Assessment of process capabilities in transition to a data-driven organisation: A multidisciplinary approach

The ability to leverage data science can generate valuable insights and actions in organisations by enhancing data-driven decision-making to find optimal solutions based on complex business parameters and data. However, only a small percentage of the organisations can successfully obtain a business value from their investments due to a lack of organisational management, alignment, and culture. Becoming a data-driven organisation requires an organisational change that should be managed and fostered from a holistic multidisciplinary perspective. Accordingly, this study seeks to address these problems by developing the Data Drivenness Process Capability Determination Model (DDPCDM) based on the ISO/IEC 330xx family of standards. The proposed model enables organisations to determine their current management capabilities, derivation of a gap analysis, and the creation of a comprehensive roadmap for improvement in a structured and standardised way. DDPCDM comprises two main dimensions: process and capability. The process dimension consists of five organisational management processes: change management, skill and talent management, strategic alignment, organisational learning, and sponsorship and portfolio management. The capability dimension embraces six levels, from incomplete to innovating. The applicability and usability of DDPCDM are also evaluated by conducting a multiple-case study in two organisations. The results reveal that the proposed model is able to evaluate the strengths and weaknesses of an organisation in adopting, managing, and fostering the transition to a data-driven organisation and providing a roadmap for continuously improving the data-drivenness of organisations

Gov-PCDM : Kamu süreç yetenek seviyesi çözüm modeli.

Quality problems in public domain have significant impact on society. They usually materialize as employee and citizen dissatisfaction, high costs and defect rates. As better processes will result in higher quality, the government processes need to be improved. There is a lack of systematic guidance on how to improve the quality of government processes. Although the customization of process capability/maturity models to specific domains/sectors might help, the public sector has special characteristics, which call for a specific process improvement model. This thesis presents Government Process Capability Determination Model, referred as Gov-PCDM, which utilizes the basic principles of a software process capability model of ISO/IEC TR 15504 and specializes the model for the government domain. It includes the governmental specific process definitions, a method including how to perform the assessment in a structured way, and a measurement framework providing objective rating. It is a structured and standardized approach that enables assessment of the governmental processes in a consistent, repeatable manner. It is assisted by adequate measures with guidance on actions to take to increase quality in government institutions. Development and validation of the proposed model are achieved through case studies. We performed a multiple case study, including 25 process assessment in total in four different organizations, is performed for validation. The results show that the Gov-PCDM is applicable for identifying the current state of the process capability and the gaps with the assessed capability level of the processes performed in governmental organizations.  Ph.D. - Doctoral Progra

The widespread use of smart sensor and actuator technologies in hospitals allow us to improve healthcare services by collecting data from various medical devices. Therefore, hospitals grasp noteworthy potential to convert these collected data into valuable information for predictive maintenance of biomedical devices. However, in order to obtain maximum benefit from the predictive maintenance system to reduce maintenance costs and improve healthcare services, a well-integrated solution is needed to combine cloud computing and IoT technologies with medical imaging devices. Despite some promising efforts in this area to solve this problem, they are not sufficient to be used in the information era. Thus, in this study, we primarily focus on the problem of how to define a predictive maintenance framework for medical imaging devices based on cloud computing and IoT technologies. Then, we identify the benefits and challenges of the proposed predictive maintenance framework. Anahtar Kelimele

Developing Process Definition for Financial and Physical Resource Management Process in Government Domain

Public Financial and Physical Resource Management (PFPRM) is becoming a core competency critical to a government organization's competitive advantage. Recent studies have shown that organizations with established PFPRM are able to generate millions of dollars in additional savings and have a distinct competitive advantage. Our literature review showed that there is also a lack of a guideline for process capability determination and improvement of PFPRM. On the other hand, after observing benefits in software organizations, The ISO/IEC 15504 is used as a baseline to generate capability/maturity models for different specific domains/sectors. Accordingly, the same approach is utilized in the government domain, and process definition of PFPRM based on the requirements of ISO/IEC 15504 is developed. Therefore, PFPRM can be assessed based on ISO/IEC 15504 to be consistently applied, managed, and controlled across governmental agencies. A case study, including the assessment of an organization's PFPRM capability level is performed. The assessment results are used to develop a road-map for implementing process improvement in the study. The initial findings show the applicability and adequacy of the proposed approach
