Choose tactics

Perspectives

(Section 4.3)

Mapping of requirements onto

qualities (a.k.a. perspectives) and

identification of suitable tactics for

how to address said qualities.

These tactics can be understood as

architectural ―lines of attack.‖

Minimum set of perspectives and associated tactics.

Make design

choices

Design choices

(Section 5.2.10)

By means of the tactics identified in

the previous step, identify design

choices for addressing the

underlying qualitative requirements.

Comprehensive taxonomy of tactics and associated design

choices.

View mapping of

requirements

Non-functional

views (Section

4.2.3and Section

4.2.4)

Perform first mapping of non-

functional view requirements (and,

where expedient, of qualitative

requirements) onto the information

view and the deployment and

operational views.

Overview of IoT-specific aspects of these views and how to

model them.

Functional view

(Section 3.5 and

Section 4.2.2)

Perform first mapping of functional

requirements (and, where

expedient, of qualitative

requirements) to FCs. Identify

interfaces needed.

Description of FGs and FCs.

Appendix C Define basic functions, interfaces,

and interactions for functional view.

The Appendix C provides exhaustive text on the FCs, related

technical-use-case diagrams, descriptions of basic FC

functions and high-level interfaces, as well as elementary

interactions of FC and their basic functions (sequence charts).

Interactions (Section Define system-wide interactions of The Interactions Section provides examples of how such
