Paraphrasing Charlton and Adras, management is a process by which managers reflectively model and share a representation of their own processes to enable themselves to perform their eponymous information-processing activities of monitoring, evaluating, predicting, and controlling their enterprise and its systems. [@Charlton2003] Furthermore, managers manage for particular purposes. Purpose-driven, they acquire systems to address the needs of the enterprise and they manage their stakeholders, engineering lifecycle tools, and artifacts during the acquisition processes to attain certain goals.

Introduction

Diocles the Magnesian (circa 150 BC) said, “the Stoics agree to put in the forefront the doctrine of presentation and sensation, inasmuch as the standard by which the truth of things is tested is generically a presentation, and again the theory of assent and that of apprehension and thought, which precedes all the rest, cannot be stated apart from presentation. For presentation comes first; then thought, which is capable of expressing itself, puts into the form of a proposition that which the subject receives from a presentation.

Pathos

Aristotle claimed that, “the speech that takes place in the assembly is defined as the deliberative species [where] the speaker either advises the audience to do something or warns them against doing something. Accordingly, the audience has to judge things that are going to happen in the future and they have to decide whether these future events are good or bad for the polis.”

“I keep six honest serving-men

Their names are
What and
Why and
When
And How and Where and Who.”

[@Kipling2009]

Introduction

• Modern MBSE tools are adequate for modeling once the adequately stable compositions of sufficiently static units of structure and behavior.
   
• Systems engineers and managers struggle to use these tools to specify, analyse, present, and manage these models as stakeholders and architects incrementally evolve those models over time and across space.
   
• Therefore, engineering lifecycle models management involves more than routine Change Management.
   
• Rather, management includes the formidable service of providing to decision-making stakeholders the arguments that demonstrate the adequacy of contextually-specific solutions to the enterprise’s problems.

Claim

Whereas

• Decision-making stakeholders need
      dialectical (i.e. logical) arguments
  for a proposed system’s satisfaction of constraints such as those that are available from adequately formal modeling notations, solvers, and practices.
   

• In addition, they need
      rhetorical (i.e. persuasive) arguments
  ​that convince those stakeholders of the aptness of proposals through trust of the proponents and through warrants which appeal to generally accepted grounds.

Claim

Therefore

300,000 hrs

Motivation

Meeting-Based Systems Engineering
is a
Chronic Waste of Time and Money

15%

• HBR “This Weekly Meeting Took Up 300,000 Hours a Year”, reports that modern enterprises spend over 15% of their staff time in meetings.  (Mankins, 2014)
  
   
• Guardian “Meetings: even more of a soul-sucking waste of time than you thought”, reports that modern meetings foster only decision-making on the most trivial of issues. (Burkeman, 2014)

Motivation

Meeting-Based Systems Engineering
is a Waste

But this undesirable form of "MBSE"
is the symptomatic consequence
of managing enterprises by

neglecting Arguments
and by
focusing on Artifacts.
