Tensions between software development methodologies and user-centered design (UCD) have always existed, but waterfall methodologies do provide a process context within which UCD methods can be clearly integrated whenever this is required. Popular agile methodologies such as Scrum create different challenges to integrating UCD. However, fitting UCD into agile methodologies will not necessarily result in high software quality. The combined approaches can still have significant design gaps that must be addressed by additional creative design practices. This chapter relates selected historical methodological trends to tensions between software and creative design. To resolve these tensions, innovative software development needs to draw on creative design practices in addition to UCD and agile methods. Specifically, innovative software development needs to draw on three key insights from design research: creative design work co-evolves problem and solution spaces; design materials talk back; and, the best design work is generous in scope and intent. These three insights are used firstly to structure a critique of the Agile Manifesto and secondly to provide the basis for proposing a balanced approach to software development that can appropriately integrate engineering, user-centered and creative design practices.

This study presents a content control application usage on smartphones which can improve collaboration between children and parents. The importance of the parents' role is to provide a comprehension regarding the content of the application to children will make good communications between parents and children. So, the children can think and make decisions on something that they face. Parental control application is made to control and limit the use of applications on smartphones by children. But the existing application has a problem on the user interface. They designed just only show the same features that the application block by the parents and are not designed to involve children in the process of selecting applications. Thus, the chance of parents to help children understand the contents of the application could possibly be missed. Because the user interface is closely related to the tasks performed by users, the user interface has a role in a parental control application design. To build a good parental control application, it is necessary convenience when a user interacts with the application system. This is a consideration in this study that focused on the user interface. Design methods that will be used in designing the user interface is User Centered Design (UCD). UCD is a method in designing user interface design with a focus on what the user needs. This method will help research to provide user data that parents and children directly, so the search process more accurate data is obtained. UCD has a life cycle stage design, so the design is made to be better. The result of this research is obtained parental control application user interfaces that provide children's freedom in choosing the content of applications and needs of parents in educating children regarding the content of the application being used so parents can educate a child.

An organization usually has events that need to be publicized to the wider community. The Indonesian Professional Assessors Association (IASPRO) only uses social media to publicize events such as seminars, workshops, or other events that are held. As a result, many organizational members or potential participants do not know that the event is being held or are even confused about registering and finding out what the participant quota for the event is. To make it easier for potential participants, a system is needed to organize event publication and registration. Therefore, an event management system is created, namely a web-based application with a User-centered Design approach. The use of the User-centered Design method aims to produce a system that suits the needs and comfort of the user. At the testing stage, the author uses the System Usability Scale method to evaluate the system interface, and black box testing to measure software functionality and ensure the software meets user needs. Test results using the System Usability Scale obtained an Acceptability range value of 81.67 with Grade A, with these results it is certain that users are satisfied with the current interface design.

Rational: Lymphangioleiomyomatosis (LAM) is a rare, progressive interstitial lung disease (ILD) predominantly affecting women of reproductive age. Improving access to structured exercise through home-based programs is attractive in LAM and other ILDs, but monitoring exercise pulse oximetry and outcomes can be challenging for patients far from specialized pulmonology centres. A preliminary study of a remotely-monitored exercise program demonstrated improvement in 6-minute walk test (6MWT) distance without safety incident, indicating mobile technology with remote monitoring may provide a feasible solution for broader access. For use during LAMFit, a fully-remote, structured exercise program for LAM, we aimed to develop and test a mobile health application to enable remote assessment of 6MWT and home monitoring of pulse oximetry during exercise. Methods: Application development involved multi-stakeholder engagement and collaboration between LAMFit investigators, patient representatives, LAM care providers, and software developers. Feature design was informed by 2002 American Thoracic Society (ATS) guidelines for the 6MWT. The application was deployed in a 28-week LAMFit pilot in 25 women with LAM (mean±SD, age 52.6±14 years). Weekly exercise sessions were remotely monitored via the application, and remote 6MWT and validated patient questionnaires were completed at weeks 2, 14, and 27. System Usability Scale (SUS) scores, a standardized metric to assess user perceptions and ease of system use, were collected at weeks 2 and 28.Results: Collaborative co-design facilitated the creation of a mobile application for the LAMFit program. Iterative design, testing and refinement, guided by steering team feedback, incorporated adjustments in language, font size, icons, and audio prompts, and enabled 6MWT to continue during brief connection-loss with the Bluetooth-enabled pulse oximeter. All 25 patients successfully used the application to complete surveys and multiple 6MWT. System usability (SUS) at week 2 was 50.625 (SD 3.227), and 52.62 (SD 4.292) at week 28. On exit survey, 88% of participants found it feasible to conduct a remote 6MWT at home using the mobile health app. Conclusion: A collaborative co-design approach enabled alignment of the application with users’ needs, enabling successful implementation of the technology. SUS scores increased during the study, suggesting improvements in perceptions of usability with increasing familiarity. However, both scores are below the industry average SUS of 68, indicating potential for further improvement in application usability. Examination of application usability during LAMFit's pilot study provides insights to inform the refinement of the application prior to scaling up the program, optimizing a digital-health solution that supports patients with LAM exercise routines
