Extending the Enterprise
An inventory of mobile devices in use within the organization should be
conducted regularly, to ensure that enterprise resources are made avail-
able in an accessible manner. Apple's popular iPhone, for example, cannot
be used to access Flash-based Web content. If an enterprise application
or Web portal relies on Flash, it becomes inaccessible to a very popular
device type.
Information aggregators, dashboards, and Web portals can aid the
mobile user by providing a single target for accessing enterprise resources.
Dashboards that consolidate information into simplified presentation
can aid limited-bandwidth access, with additional detail made avail-
able through drill-downs and linked documents. Applications designed
for server-side processing can reduce the on-device CPU impact, as well
as the data throughput requirements found in many client-server desk-
top applications. Extranets designed for partners and supplies can aid in
cross-functional data sharing by avoiding the need for application deploy-
ment or external-authentication data connections.
Accessibility
In addition to mobile device constraints, applications should be developed
for availability through alternate-accessibility interface types. Section 208
of the Rehabilitation Act of 1973 (amended 29 U.S.C. 794d) provides
guidelines for federal agencies to provide services and electronic informa-
tion to individuals with disabling conditions. These guidelines have been
implemented across many state, corporate, and industry interpretations,
and can serve as a good reference for applications designed to meet acces-
sibility standards.
Table 9.1 illustrates some options for addressing Section 508 guidelines.
This is not an exhaustive analysis of all possible solutions for all required
standards, but it should serve as a starting point for consideration.
Mobile and Remote Access
Many types of devices are currently enabled for mobile or remote access,
including standard formats such as the laptop, netbook, tablet, and “smart”
phone. However, increasing numbers of devices may also include mobile
