This chapter is the first in a series that reviews the requirements analysis and definition for IDCM functional requirements. We noted in Chapter 10 that functional statements are an integral part of the development of system requirements specifications for IDCM systems, as distinct from the user requirements that we covered in Chapter 11. In this chapter, we focus on the functional requirements analysis of digital documents within the office environment of business and government enterprises. We consider requirements that are applicable to most types of these documents. Some characteristics that are specific to email, digital drawings, imaging, workflow, and Web content, are discussed in separate chapters. We also provide a series of functionality checklists that practitioners should find useful when defining the functional requirements for IDCM. Our objectives are to explain the attributes and how these may be expressed in requirements analysis for: • Document authoring; • User profiles; • Document volumes; • Document capture; • Metadata utilization; • Storage handling; • Version control; • Renditions; • Compound documents; • Association through hyperlinks; • Full-text indexing and retrieval; • Document viewing; • Printing; • Security and audit; and • Scheduling for archives or disposal.
