“…Kualitas adalah salah satu kunci kesuksesan sebuah website. Kualitas didefinisikan sebagai sekelompok karakteristik dari sebuah perangkat lunak yang menunjukkan kemampuan perangkat lunak tersebut dalam memenuhi kebutuhan pengguna (Behkamal, Kahani and Kazem, 2009) (Parsazadeh et al, 2018). Salah satu karakteristik kualitas perangkat lunak menurut ISO 9126 adalah usabilitas.…”

“…Sebagian besar website tersebut sangat bermanfaat bagi pengguna. Namun, usabilitas yang kurang baik mengakibatkan pengguna mengalami penurunan motivasi, frustasi, dan membuang-buang waktu (Torrente et al, 2013) (Parsazadeh et al, 2018). Pengukuran atau evaluasi usabilitas adalah metode untuk mengukur aspek-aspek usabilitas dari sebuah antarmuka dan mampu mengidentifikasi persoalan-persoalan terkait.…”

Kualitas merupakan faktor utama kesuksesan sebuah website. Salah satu karakteristik kualitas perangkat lunak menurut ISO 9126 adalah usabilitas. Pengukuran usabilitas sebuah website adalah hal yang penting mengingat sangat besarnya jumlah website saat ini. Salah satu metode yang dapat digunakan untuk mengevaluasi usabilitas website adalah framework Sirius. Sirius dapat menghasilkan nilai usabilitas global dan daftar elemen antarmuka sistem yang perlu diperbaiki. Namun, elemen-elemen ini belum diatur berdasarkan prioritas pengembang sistem dan hanya mempertimbangkan nilai peningkatan yaitu prosentasi perbaikan nilai usabilitas global jika elemen tersebut diperbaiki. Untuk itu dibutuhkan sebuah teknik untuk memprioritaskan elemen-elemen tersebut berdasarkan sudut pandang pengembang sistem sehingga sesuai dengan sumber daya yang dimiliki oleh pihak pengembang. Salah satu teknik yang dapat digunakan adalah Moscow. Moscow dapat mengelompokkan seluruh kebutuhan ke dalam 4 (empat) kelas berdasarkan tingkat prioritasnya. Penelitian ini melakukan modifikasi terhadap framework Sirius dengan menambahkan tahap perangkingan menggunakan teknik Moscow. Berdasarkan hasil pengujian, penambahan tahap pengaturan prioritas dengan Teknik Moscow memberikan urutan kriteria usability yang lebih baik dalam hal nilai bisnis, resiko, dan biaya pembangunan website. Setiap tim pengembang website yang dianalisis memberikan hasil pengaturan prioritas Moscow yang berbeda-beda. Bagi tim website Lective, kriteria usability paling penting adalah berkaitan dengan aspek labelling, sedangkan bagi pengembang website Seminar Indonesia, aspek paling penting adalah kelompok comprehensibility and ease of interaction. Adapun pengembang website Simkesmas lebih menekankan pada aspek control and feedback. AbstractQuality became the key element for website deployment. Based on the ISO 9126, one of the quality characteristics in software engineering is usability. The usability measurement on a website is an essential topic nowadays along with the incremental growth of it. One of the evaluation methods that can be used for analysing website usability is Sirius Framework. This method can produce global usability values and the list of a user interface element that should be modified. However, those elements have not been adjusted based on developer priority system which only considers the increased value of each element - the percentage of modified global usability value. Therefore, A technique called MoSCoW was introduced for prioritizing those elements from a developer point of views which corresponds to its available resource. MoSCoW can categorize all of the requirements into 4 distinct classes based on priority. This paper was performed for extending the Sirius Framework for implementing the ranking system by using MoSCoW. The experiment results showed that the MoSCoW method for priority adjustment process could produce better usability criteria on business, risk, and cost value during website development.

“…There have been many studies on usability evaluations of mobile applications [23][24][25][26][27][28]. Some of these propose methodologies for usability evaluations of mobile applications in diverse application domains, such as mobile learning applications [24], mobile fitness applications [25], and mobile sale force automation applications [26]. In this paper, we evaluate the usability of our prototype mobile application for tea recommendation.…”

“…These were the usability of the TeaPick TM mobile application, the perceived usefulness of the application, the satisfaction with recommendation, the intention to use the application, and the attitude toward recommended tea brands (i.e., brand attitude). We included 5 questions per construct based on the previous research [24,[27][28][29]. The type B questionnaire was designed to evaluate the overall acceptability after users had sampled the recommended tea.…”

The rapidly growing interest in healthy lifestyles and the health benefit of foods and the growing tea-consuming population are driving the growth of the tea industry. In particular, the growing preference among Millennials for premium blended tea is leading the growth of the tea market. In this paper, we study the feasibility of recommendation services for blended tea, which has not been addressed well by existing recommender systems. To this end, we design TeaPickTM, a mobile application that suggests a blend of tea suited to the user’s preferences including desired health benefits. To evaluate the application and its recommendations, we conduct not only a usability test, but also a consumer acceptance test with 31 participants. Our user study shows that the participants were positive about the recommendation service provided by our application and were generally satisfied with the recommended tea.

“…Therefore, in this study the focus is on quality-in-use issues, which are recognized as the subject of interest of usability and user experience (UUX) practitioners. The evaluation of the UUX of a mobile application has been identified by many as one of the main challenges [4,5,6], eventually determining the success of its continued acceptance by users.…”

The variety of hardware devices and the diversity of their users imposes new requirements and expectations on designers and developers of mobile applications (apps). While the Internet has enabled new forms of communication platform, online stores provide the ability to review apps. These informal online app reviews have become a viral form of electronic wordof-mouth (eWOM), covering a plethora of issues. In our study, we set ourselves the goal of investigating whether online reviews reveal usability and user experience (UUX) issues, being important quality-in-use characteristics. To address this problem, we used sentiment analysis techniques, with the aim of extracting relevant keywords from eWOM WhatsApp data. Based on the extracted keywords, we next identified the original users' reviews, and individually assigned each attribute and dimension to them. Eventually, the reported issues were thematically synthesized into 7 attributes and 8 dimensions. If one asks whether online reviews reveal genuine UUX issues, in this case, the answer is definitely affirmative.
