Re: [SysSciWG] Systems Health

[Jack Ring]

Great points. Helps clarify the issues.

I am not suggesting dialog on ‘improving health’ or ‘monitoring health’ until we have a specification of the 'existence of health and not health.' 

The World Health Org. does not, i.e, 

"The World Health Organization (WHO) defined health in its broader sense in its 1948 constitution as "a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity."^[2][3] This definition has been subject to controversy, in particular as lacking operational value, the ambiguity in developing cohesive health strategies, and because of the problem created by use of the word "complete".^[4][5][6] Other definitions have been proposed, among which a recent definition that correlates health and personal satisfaction.^[7] [8]Classification systems such as the WHO Family of International Classifications, including the International Classification of Functioning, Disability and Health(ICF) and the International Classification of Diseases (ICD), are commonly used to define and measure the components of health.”

An example of the need for a specification of a healthy system is highlighted by those who are concerned with evolving a system (as in Clayton Christenson’s Disruptive Innovation) because an example of a ‘pathology’ may be simply a discontinuance of an unwanted behavior, therefore an improvement.

I am saying that we need to address “When is a configuration a system and not a system” and suggesting that the criteria of Fit For Purpose will be one perspective.

In my understanding this point has been made by Derek Cabrera for several years and is addressed in the P of DSRP.

Make sense?

I think a "Systems Health" working group or project (as part of SSWG?) is an excellent idea.

Glad you are offering to help with it, and look forward to your activities.

I note that for centuries medicine has concentrated on pathologies (i.e. how we get sick and die) and has only recently given attention on improving health. However, the study of pathologies is an outstanding success! A favorite example is the Ghost Map (https://en.wikipedia.org/wiki/The_Ghost_Map)

There appears to be a great deal of interest in monitoring system health for computer systems.

If you are saying that Sillitto, Troncale or Cabrera have stated a ‘framework’ for system health with respect to which one can claim pathologies, then please share it with us. 

Or are you claiming that a pathology claim does not have to be in the context of a ‘healthy’ system Or what?

FWIW, I do not find that “each proponent of a framework appears to believe theirs is the best, and that others should fall in line and use it.” 

Rather, I have found, at least with Sillitto, Troncale, and Cabrera that each are quite willing to share and rationalize their framework. It is just that I am unaware of any specification of ‘healthy’ system by any of these three.

Cheers,

A few folks work on combining differing system viewpoints, and that makes their work more useful to me. Stilleto, Troncale and Cabrera come to mind.

In the agenda below will anyone present the criteria for stating what a system is intended to do in the first place?  For example, the necessary, sufficient and efficient attributes of a system that is Fit For Purpose?

If not, then pathology of what? How will the various ideas about pathology (ways a system fails to accomplish acceptable behavior), e,g,, 

http://www.sciencedirect.com/science/article/pii/S1574789111001438

be justified or examined for fallibility?

Also, given that systems happen via a system generation chain, e,g,, 

S0 = Operational SoS

S1 = Deployed System

S2 = Sociotechnical system that produces one or more instances of S1.

S3 = Sociotechnical System that Generates Recipe for (model of) S1US2

S4 = Social System

      That Enables S3

will the pathologies described be related to these respective stages of generation or applicable to all or what?

If this session would appreciate a candidate example of 'Fit For Purpose’ applicable to each of the above, I will be happy to provide one — in advance to foster dialog.

Else, wishing you a productive session.

Too many of us do what we know how to do instead of what must be done.

The Systems Pathology project will be conducting sessions during the INCOSE Workshop on the afternoon of Sat, Jan 28th. To register, go here: http://www.incose.org/IW2017/home

We will cover at least nine different views or perspectives or approaches of Systems Pathology for Systems Engineers as well as initiate a professional society and its products and conferences for future development of Systems Pathology. 

• 1530-1545     Troncale     (will present a summary of the SPT-based, top-down Systems Pathology work of SSWG; note its     similarities and differences from NSWG work; summarize the SysPath related work of Miller, Swanson, Odum, Schindel, Gall)
  
• 1545-1600     McNamara will design and plan the follow-up activity esp. of the NSWG
  
• 1600-1615     Kerschmann     (will present
  
• 1615-1630     Activity-Discussion
  
• 1630-1645     Davidz     (will present her graduate student work on SE-related Systems Pathology, her detection of patterns in SE project failures, & describe interest of the next generation of SE’s in SysPath)
  
• 1645-1700     Activity-Discussion
  
• 1700-1715     Katina     (will present his graduate student work on systems applied to complex systems, with a focus on critical infrastructure, risk, & vulnerability, as well as describe interest of the next generation of SE’s in SysPath)
  
• 1715-1730     Activity-Discussion
  
• 1730-1745     Troncale     ((will present a “manifesto” for top-down Systems Pathology; announce specifics of initiation of an Int’l Society for Systems Pathology (ISSP); enroll Founding Members; describe the next year of ISSP Products and Activities))
  
• 1745-1800     Sign-ups and planning of 2017 ISSP activities
  

We hope to you see you there.

Some Short Bio Notes: Some of the presenters may be unknown to you receiving this email. So I have summarized biographies below.

Dr. Russell Kerschmann is an M.D. from N.A.S.A. Ames Research Center (ret.) and a Subject Matter Expert for the N.A.S.A. Engineering and Safety Center. He has presented a Webinar for NSWG on “How Living Things Fail, and Why It Should Matter to Engineers,” available on the NSWG website and which we regard as closely related to the umbrella of Systems Pathology. His focus is on medical (anatomic/clinical) pathology. Although an UG EE, he does not consider himself an SE but thinks the systems perspective would be a help to failure analysis.

Dr. Heidi L. Davidz is a Systems Engineer for Aerojet Rocketdyne in West Palm Beach, Fl. Previously she was Discipline Lead in Systems Engineering at UTC Pratt & Whitney Rocketdyne. Her Ph.D. education was at MIT (BS in Mechanical; MS in Aerospace). She has witnessed and documented patterns of failure in SE execution through her dissertation work and her work at several companies. 

Dr. Polinho Katina, BSc, MEng Ph.D. is a Postdoctoral Researcher at the National Centers for System of Systems Engineering at Old Dominion University in Norfolk, Virginia, where he is also an Adjunct Assistant Professor in SE. His research focused on the relationship between Systems Theory and Problem Formulation for governance of complex systems.

Dr. Len Troncale is Professor Emeritus and Past Chair, Biological Sciences and Founding Director Emeritus of the Institute for Advanced Systems Studies, California State Polytechnic University, Pomona, CA. He was also past Managing Director of the Int’l Society for General Systems Research (SGSR) and past President of the Int’l Society for the Systems Sciences (ISSS). He is lead for two of the official INCOSE-SSWG ongoing projects.

Hi Jack - I hope things are going well for you moving into this next demarcated stretch of time, jocularly known as a 'new year'.

I just thought I would mention briefly that a majority of my attention for the last couple of years has been explicitly focusing in on the ideas of life and death, health and ill-health, diagnostics and remediation of the enterprise as a living system.  As you know, this was the dominant theme of my book.  I wonder if this source of captured thought has been introduced to your team?  I am working with a few colleagues to push this forward in a sort of equivalent, combined, Gray's Anatomy, Physician's Desk Reference, and Pharmacopoeia for the enterprise.  

How can we best keep an eye on this work that you're involved in, to the extent that it has relevance for the work I just mentioned?

Thanks!

Doug

It is not clear that the ASTEWG is going to be active. Check me in February.

Meanwhile you might want to consider joining the Natural Systems WG. Do no have to be an INCOSE member.
