DCR exercise effectiveness How well project ratification and monitoring—the activities
associated with project DCRs—are accomplished during
the ISD process. Such activities include project budget and
schedule specification, establishing project expectations,
and establishment of milestones and project deliverables.
5 Newly developed scales;
conceptually derived from
Fama and Jensen (1983).
DMR exercise effectiveness How well project initiation and implementation—the activities
encompassed by project DMRs—are accomplished during
the ISD process. Such activities include system architecture
development and design, development methodology selection,
choice of programming language, and implementation
of the desired features and functionality in the system.
6
IT unit’s business application
domain knowledge
The IT unit’s knowledge of the business processes, business
rules, policies and procedures, and the business objectives
associated with the project’s problem domain.

Client department’s technical
knowledge
The client department’s knowledge of software design,
programming, and software development processes.
6
ISD efficiency The extent to which a project is completed on schedule, within
budget, and with minimal extraneous rework.
