Introduction

Epistemology

Definition Theory of knowledge

S-G vs. RP-G “Systemism” Case of SE

Main questions 1. Who is the knowing subject?

J-P.Micaëlli, Is SE compliant with systemism?

2. What does he know?

3. How does he know?

Gnoseology Definition of the knowable world based on a Weltanschauung (Cf. 2) 3/9

Introduction Epistemology

S-G vs. RP-G “Systemism”

Substantive Gnoseology

Relational-Processist Gnoseology

The Universe is a structured set of beings possessing fixed attributes & encapsulated laws explaining their dynamics.

The Universe is a grid of intricate processes. Beings and their attributes are temporary state of these processes.

An Aristotelian ontology of the Universe is desirable & possible.

Knowing is an endless open-end process. An ontology is a contingent tool

“Systemism”

S-G vs. RP-G

“Systemism”

J-P.Micaëlli, Is SE compliant with systemism?

Case of SE

System as an abstract but... …empirical-based

(Cf. 2)

…contingent

(Cf. 1,2,3)

…complex

(Cf. 1,2)

Systems engineering Introduction Epistemology S-G vs. RP-G “Systemism”

Case of SE

“[...] interdisciplinary collaborative approach to derive, evolve, and verify a life-cycle balanced system solution which satisfies customer expectations and meets public acceptability” (IEEE 1220)

J-P.Micaëlli, Is SE compliant with systemism?

System “[...] combination of interacting elements organized to achieve one or more stated purposes (…) The term Systems defines a “concept” characterized by a set of properties such as the function provided, external interfaces, architecture(s) [...]” (AFNOR 15288)

7/9

Contingency Introduction Epistemology S-G vs. RP-G “Systemism”

Case of SE

Who are the subjects identifying the system of interest? How do they identify it? What are the enabling processes & tools?

Monist & pluralism

J-P.Micaëlli, Is SE compliant with systemism?

How to build an epistemic community having pluralist views on the system (monism)?

Conceptualize SE as an activity

Openness What are the interactions between SE framework and other frameworks complex design requires?

8/9

Conceptualize SE as a part of the design tools
