2.2 Usability Attribute from users experience

As explained in detail about the concept of usability, it indicators are derived from user expectations and needs. Hence in the previous study shows usability is to facilitate organization goals or aim or to help facilitate the end users in achieving their dreams or mission to complete a task. Table 1 shows the attributes of usability assessment in achieving the quality of the task or service from the evaluation of end users perspective and experience, which the value comes from the effectiveness, efficiency and users satisfaction.

In this article user mean those who actually use learning environment, service and activities, it, including student, educators and support -staff. Today built environment presenting complex challenges to professional designer. Design is an evolutionary process that attempts to create

beyond our best imagination to the real world. Design forms what we desire and what we need sometimes it follows by design trend but a good design considered the resources and human end- user participant.

In other way usability also is a component of user‘s participation or organization as the co- designer as they will experience the future space other than architect and experts in driving

design process. Previous research had shown that participants and allow opinions from the end – user in the design process, influence design outcome, which satisfied and more functional and friendly [7;19] .

The user's feedback throughout their experience, become an information or key answer to improve the service performance [3;4] .In order to do this, clients, designers or facilities

management must know how the space works and why. Understanding how things work and why requires us to analyze and explain [12] .Therefore it is important to understand the concepts of usability, in order to provide a better understanding of the users‘ experience and give positive views to the organization [9] .

Furthermore, in many situations in the built environment, effectiveness design able to be seen after the service delivered and space being utilized by the end users, only the users can judge or response to the service outcome. In this situation facilities management is needed in planning space and facility to become more organized, at the same time the strategic facilities'

management process is used to understand the organization flow and mission [13; 14] and consequently, the use of space becomes more valuable [15]. Figure 3 shows the user s experience

and the expectation of what they want to perceive during their experience.
