Information systems (IS) are indelibly linked to the global economy and are
indispensable to society and organizations. Despite the decisive function of IS in
organizations today, IS development problems continue to plague organizations.
The failure to get the system requirements right is considered to be one of the
primary, if not the most significant, reasons for this high IS failure rate. Getting
requirements right is most notably identified with Frederick Brooks' contention that
requirements are the essence of what IT professionals do, all the rest being accidents
or risk management. However, enterprise architecture (EA) may also provide the
discipline to bridge the gap between effective requirements, organizational objectives,
and the actual IS implementations.
The intent of this research is to examine the relationship between IS
development capabilities and requirements analysis and design capabilities within the
context of enterprise architecture. To accomplish this, a survey of IT professionals
within the Society for Information Management (SIM) was conducted.
Results indicate support for the hypothesized relationship between IS
development and requirements capabilities. The hypothesized relationships with the
organizational demographics were not supported nor was the hypothesized positive
relationship between requirements capabilities and EA perceptions. However, the
nature of the relationship of requirements and EA provided important insight into the
Here’s what’s next.
