The HCI/E approach is grounded in a Conception of the HCI Engineering Discipline (Long and Dowell (1989) – see Section 1) and of the HCI Engineering Design Problem (Dowell and Long (1989) – see Section 2) – both products of the research. Unlike these two conceptions, however, the HCI/E Conception of Engineering Design Knowledge has no single paper dedicated to its exposure. Rather, it appears throughout the Discipline and Design Problem conception papers. For this reason, 3.5 presents both papers in full and other sections include citations from both papers, where appropriate. Together the two papers present the complete HCI/E Conception of HCI Engineering Design Knowledge.
To make the HCI/E Conception of Engineering Design Knowledge more accessible to a wide range of researchers: a complete expression appears in short versions of the Discipline and Design Problem papers (3.4); a summary version in 3.3; a generalised Engineering version in 3.2; and finally, a generalised HCI version in 3.1. The latter also serves as an introduction to the Conception. Finally, the concepts carried forward by the Conception appear in 3.6 and the EU/UCL research illustrations of HCI Engineering in 3.7.
As appropriate, a version is supported by citations (C) from the original Long and Dowell and Dowell and Long papers, which allows readers to check the derivation of the version from the original. (F) indicates footnotes.

3.4 Short versions of Long and Dowell (1989) and Dowell and Long (1989)
These two papers together expose the Conception of HCI Engineering Design Knowledge. Short versions of the papers, relevant only to the topic of HCI Design Knowledge, are presented here. Full papers can be accessed via
Long and Dowell (1989) – HCI Engineering Knowledge – Short Version
Dowell and Long (1989) – HCI Engineering Knowledge – Short Version
3.5 Full Versions of Long and Dowell (1989) and Dowell and Long (1989)
Here, the two papers are presented in their entirety, including a complete version of the HCI/E Conception of HCI Engineering Design Knowledge.
3.6 Concepts Carried Forward
The concepts carried forward in this section are: Design; Knowledge; and Design Knowledge

3.7.1 Cummaford (2000) Validating Effective Design Knowledge for Re-Use: HCI Engineering Design Principles
Cummaford here applies the HCI/E Conception of Design Knowledge to develop a conception of HCI Engineering Design Principles, as a framework within which systematically to relate design knowledge to performance.Design knowledge is illustrated throughout the paper.
