On the negative side, the condition of most of the Indian state Web portals indicated a lack of synchronization and consistent information flow between the Web teams and various state government departments. The expectations of users who have disabilities and employ assistive technologies must also be included. IEC 62508 categorizes the ISO TS 18152 activities by project stages and gives guidance on how they are applied to achieve whole system integrity.

Utilitas mengacu kepada fungsionalitas sistem atau sistem tersebut dapat meningkatkan efektifitas dan efesiensi kerjanya. Hence, even if software designers perceive that redesigning the architecture to support a certain number of usability mechanisms involves changing or adding a considerable number of classes, the changes at the code level can be lower. Each row presents results from the usability review of a state in India. Android applications have a particular sensitivity to two particular aspects of usability responsiveness and seamlessness.

The reasons are threefold: there are methodological challenges to defining verifiable, valid, and comprehensive usability requirements; it is very much contrary to what seems to be the current development culture; and it may be difficult for bidders on competitive projects to estimate the required usability efforts in their proposals. Android applications can suffer from responsiveness problems due to the existence of concurrent background services and activities that may slow processor performance. Aplikasi yang dibuat di sini dirancang khusus untuk memudahkan penggguna yang memakai aplikasi tersebut. Usability adalah suatu ukuran, dimana pengguna dapat mengakses fungsionalitas dari sebuah sistem dengan efektif, efisien dan memuaskan dalam mencapai tujuan tertentu.
