layers of limits (thinking in systems)

 
([ 
    Progress is held up when a [“limiting factor”] forms in some component or subsystem, but then [Progress] begins again when the problem is solved – until the next [“limiting factor”] forms.

    This cycles of addressing the next [“limiting factor”] continue until the development of the technical system is exhausted; or until someone or a team of people over a period of time is able to overcome the next [“limiting factor”], then the technical developmental cycle is reset, begins again, or restarted.  

    If you were to replace the idea of “limiting factor” with the idea of “reverse salients”, or with the idea of “parameter threshold”, then the same general  message (pattern) should apply.

“parameter threshold” [4]
In an efficient technique this value must be no less than some minimal level, named by Boris I. Goldovsky as “parameter threshold” [4]. Provision for lift power exceeding aircraft weight by 10 to 20% was a threshold. This condition was necessary for reliable flight of an aircraft. Another threshold was connected with the distance a steamer could travel without refueling. This threshold alone has determined the transition from a steamboat to steamship and then to an ocean liner. A necessity to overcome the parameter threshold of the currently limited technological capabilities of a society determines the mode of performance of a technique to be invented and categorizes the problems to be solved in the second case.

   The limiting factor, to the next potential limiting factor: 
 
  “There are layers of limits around every growing plant, child, epidemic, new product, technological advance, company, city, economy, and population. Insight comes not only from recognising which factor is limiting, but from seeing that growth itself depletes or enchances limits and therefore changes what is limiting. The interplay between a growing plant and the soil, a growing company and its market, a growing economy and its resource base, is dynamic. Whenever one factor ceases to be limiting, growth occurs, and the growth itself changes the relative scarcity of factors until another becomes limiting. To shift attention from the abundant factors to the next potential limiting factor is to gain real understanding of, and control over, the growth process.”, p.102, Donella H. Meadows, Edited by Diana Wright, Thinking in systems

onions (my story)

At our farmers' market, we usually sell out of onions by midfall, which means we could be selling onions if we had them.  Frequently customers ask me why we don't grow more.  They know that onions are a storage crop (at least most cooking onions are), and they know they would buy them from us in November and December if we had them.  What they usually don't know is that organic onions are a very time-consuming proprosition for a farmer.  They grow slowly, and their slender leaves do not compete well with weeds. 
   If we planted a lot more onions, we would very likely not have enough time to keep them well weeded and irrigated.  There are many other crops to be planted and tended throughout the season.  Too many onions would mean that other crops might get short-changed, and onions are not our only allium:  We also grow shallots and garlic ── lots of garlic, in fact.  All three, being sensitive to changes in day length, are ready for harvest within the same 3- or 4-week period.  Throw in the weather, and you might have to dig or pull a lot of alliums in a short stretch of time.  There is also the challenge of curing and keeping them dry ── both of which take time and space. 
p.51
   The moral of the story:  We could grow more onions, and we could sell more onions.  But when the bigger picture is taken into account, we don't have the time to do it.
