perspectives that different stakeholders will have on the development process.
WISDM posits that simple engineering and technical strategies are not suf cient for

appropriately building Web applications (Shaffi and Al-Obaidy 2013 ), which makes

the Multiview methodology particularly adequate due to its soft systems approach.
There are five essential aspects that shape the WISDM (Shaffi and Al-Obaidy

2013 ). These ve aspects are re ections of the different levels of in uence that will

shape the final product, accordingly with its respective stakeholders, as illustrated in

Fig. 4.4 .
First, the process requires analysis of preexisting conditions. Organizational
analysis is primarily related to the creation of value in the product. This is the
client s

business goals, by focusing on market studies and information requirements.
Information analysis allows the Web developer to further establish and de

' s goal; the Web site or Web application needs to re ect the organization '

ne user
requirements, mainly by building documents with graphical notations and/or soft-
ware prototypes. WISDM commonly uses the UML Model, a representation of the
functionality of the system (Shaffi and Al-Obaidy 2013 ).

After analysis is complete, there follows the design stage. Work design is the
creation and de

nition of the relationship between customer and employee, and this
essentially entails the principle of designing the site or application with the cus-
tomer in mind. Technical design is the Web site development in itself. It concerns
the programming and data structure necessary to create the Web site (Shaffi and

Al-Obaidy 2013 ).
Finally, human - computer interaction (HCI) represents the interaction between
technical and work design, through user interface (UI) design. UI design is a critical
part of the overall Web design development process. This process should combine
technical skill, experience, and expectations of the customer/user. The Web
developer must focus heavily on the UI design of the Web site, ensuring that it will
be effortlessly accessible, usable, flexible, secured, and also supportive of ergo-

nomic features (Shaffi and Al-Obaidy 2013 ).

WISDM attempts to provide a more encompassing view of the problem of Web
development, by proposing a socio-technical view. The Multiview methodology
