0:10 - Who is Jon Holt?
1:57 - Presentation overview
3:00 - Why modelling vs. How do we model effectively and efficiently vs. How do we deploy MBSE
6:50 - The need of Model-Based Systems Engineering: Complexity, Communication, Lack of Understanding
16:20 - An Example - Consider a car...
19:45 - An Example - Complexity dimensions
30:35 - The Complexity Shape - The Brontosaurus Complexity
34:25 - The MBSE Mantra - People, Processes, Tools
35:40 - Evolution of MBSE: Document-Based to Model-Based
39:36 - Summary
41:08 - Question 1: Isn't MBSE ist just a tool approach to the Systems Engineering?
42:26 - Question 2: If the need for MBSE is no different for SE, there would be no motivation for an organisation to use model-based if it has document-based systems engineering
43:38 - Question 3: Please clarify the statement MBSE is like SE using Requirements Engineering as an example
44:48 - Question 4: Do you have an adequate definition of complexity and how does it relate to the complexity theory?
46:10 - Question 5: Is modelling a system using MBSE tools and methodology but not including executable models still count as MBSE?
47:38 - Question 6: Given that the reason for a car is not changed, is the complexity growth based on the implementation choices?
49:10 - Question 7: All of the aspects related to complexity increase of todays vehicle are related not to the functional aspects, would you agree? Shouldn't we blame ourselves for raise of the complexity?
51:32 - Question 8: How would you sell the MBSE to management or board of directors?
54:15 - Question 9: Can we predict and manage complexity using MBSE (Brontosaurus metaphor)?
