“…Our study showed that the participants' performance on the ACD comprehension test is higher for those who make more fixations compared to those who make fewer fixations, which is an indicator of an efficient search on complex activity diagram as in line with the previous studies in other domains [27], [28], [29].…”

This study investigates whether working memory (WM) capacity affects the understandability of complex diagrams and if so, whether WM training has a positive effect on their comprehensibility. Two experiments were conducted with computer science students. In the first experiment, we collected eyetracking data while participants performed comprehension tasks on an activity diagram. In the second experiment, the participants completed WM training, before and after their comprehension scores were measured. The results showed that working memory capacity can positively affect the understandability of complex diagrams, but it provided no conclusive evidence for the effectiveness of working memory training.

“…(2) PARTICIPANT PERFORMANCE (PP) MEASURE In this measure, the defect detection performance of each participant i (PP i ) is calculated. To do so, the defect detection difficulty level value of each defect (DF j ) value is used where n is the total number of defects detected by participant i, and s is the total number of defects seeded in the UML-AD &UML-ADE (Cagiltay et al, 2013).…”

System design is recognized as one of the most critical components of a software system that bridges system requirements and coding. System design also has a significant impact on testing and maintenance activities, and on further improvements during the lifespan of the software system. Software design should reflect all necessary components of the requirements in a clear and understandable manner by all stakeholders of the software system. To distinguish system elements, separation of concerns in software design is suggested. In this respect, identification of the user tasks, i.e., the tasks that need to be performed by the user, is not currently reflected explicitly in system design documents. Our main assumption in this study is that software quality can be improved significantly by clearly identifying the user tasks from those that need to be performed by the computer system itself. Additionally, what we propose has the potential to better reflect the user requirements and main objectives of the system on the software design and thereby to improve software quality. The main aim of this study is to introduce a novel notation for software developers in the frame of UML Activity Diagram (UML-AD) that enables designers to identify the user tasks and define them separately from the system tasks. For this purpose, an extension of UML-AD, named UML-ADE (UML-Activity Diagram Extended) was proposed. Afterwards, it was implemented in a serious game case for which the specification of user tasks is extremely important. Finally, its effectiveness was analyzed and compared to UML-AD experimentally with 72 participants. The defect detection performance of the participants on both diagrams with two real-life serious game scenarios was evaluated. Results show a higher level of understandability for those using UML-ADE, which in turn may indicate a better design and higher software quality. The results encourage researchers to develop specific design representations dedicated to task design to improve system quality and to conduct further evaluations of the impact of these design on each of the above mentioned potential benefits for the software systems.

The Savings and Loans Unit (USP) is an economic business that provides loans in the form of money for village community business activities for individuals or groups considered productive. The process of borrowing funds is carried out by submitting a loan proposal with terms predetermined by the USP. The purpose of this research is to make an application design for accelerated loan proposals using the Object-Oriented Hypermedia Design Method (OOHDM), which can be implemented in the recommendation system for funding loan proposal selection. OOHDM is used in the design of web applications that are oriented towards building large hypermedia. This research produces a web-based application design whose access rights can be used by the USP as an admin as well as a lending decision-maker and a fund user/borrower submitting a loan proposal.
