-====== Gall's Law ======+A Mediterranean cruise ship is without question the most varied type of cruise ship available. There are more than 120 seaports around the Mediterranean coastline, offering various mixes of cruise vacations over one-week, two-week or longer journeys.
  
-===== Variants and Alternative Names =====+A huge clash of cultures await all that select a Mediterranean cruise ship. You can go to no less than 17 various countries, including such nations as Spain, Italy, Greece and Egypt. Each nation has its very own distinct attractions, every one of which you can example as your cruise ship gracefully sails around the tranquil blue Mediterranean Sea.
  
 +More than 50 firms provide cruises along varied paths in the Mediterranean. Some firms focus on supplying Western Mediterranean cruises, focusing on ports of call around Portugal, Spain, France, Italy and Morocco. Various other business supply Eastern Mediterranean cruise ships which absorb Croatia, Greece, Turkey and nations between East.
  
-===== Context ===== +Popular expert Mediterranean cruise ships include an excursion of the North African nations, a Mediterranean islands cruise that gos to the island nations of Cyprus and Malta, as well as cruises around the Greek Islands. If you're after a longer holiday, it is feasible to arrange a cruise [[https://google.com|google travel]] plan that takes you around a lot of if not all of the Mediterranean countries.
-  * [[contexts:Process Design]] +
  
 +Background, culture, grand cities, ancient monoliths, romantic islands and impressive views are all within easy reach on a Mediterranean cruise. In the Western Mediterranean you can find the traditional white Andalucian villages of Southern Spain, sample the world-famous Manzanilla sherry in Cadiz and visit the social center of Europe in the shape of Barcelona, before taking a trip onwards to the French Riviera.
  
-===== Principle Statement =====+A cruise ship that absorbs the terrific shoreline of Italy yields such prizes as the inactive volcano of Mt Vesuvius, old Pompeii and the stunning city of Rome. The islands of Sicily and Sardinia hold lots of thrills also on a Western Mediterranean cruise.
  
-> "A complex system that works is invariably found to have evolved from a simple system that worked. The inverse proposition also appears to be true: A complex system designed from scratch never works and cannot be made to workYou have to start overbeginning with a working simple system."((John Gall: //General systemantics, an essay on how systems work, and especially how they fail//, 1975))+In the Eastern Mediterranean, cruise travelers can uncover the magnificent Croatian coast and its gorgeous city - Dubrovnik, prior to diving southeastwards to sample classic Greece and its sultry islandsThe island of Crete is constantly worth a check outif only for the historical Royal residence of Knossos.

-===== Description ===== +
- +
-process is good when it's not about building complex systems from scratch. Start with a simple system that works and enhance that. Alternatively take a set of known to be working (small) subsystems and compose them but keep sure that the composition itself does not become complex as this won't work either. Develop iteratively in small steps and frequently ensure that the result is still working. +

-  * Use iterative processes. +
-  * Reuse known to be working [[glossary:modules]]. +
-  * [[patterns:Release early, release often]]. +
-  * Use automated testing to ensure that enhancing the system does not break it. Otherwise any further steps are enhancing of a non-working system. +

-* Gall was partially correct.  All complex systems developed from simple systems but not simple systems that work.  +
- +
-Complex systems develop from simple systems that "partially work" but needed to be improved upon to fully achieve the goal.  By partially work, I mean systems that fail to achieve the desired result but produce result sufficient to the developer to motivate continued improvement and, by extension, increased complexity.  Although slightly tautological, if a simple system "worked", meaning it completely achieved the desired result, making it more complex would not only be unnecessary but foolish as to do so would require an investment of some resource and create a risk of creating a deleterious effect to the system, as any change carries with it an inherent risk of injecting error into the system and its process If the system truly works, the question becomes why would you take on the cost and the risk of changing it.  To do so would be sub-optimal unless the system had not achieved the goal in full.  If Gall believes that "works" means sub-optimal performance, then his "law" can be accepted as true; however, if that is the can "works" should have been replaced with a more specific term. Either way, the law stands as only partially correct. +
- +
-Having said this, are there systems that maximally worked that were made more complex and, therefore, meet Gall'statement.  One would have to believe so but only in the context of an addition.  Take hypothetical example of a business' distribution system.  Suppose the system is simple and effective to the point that it meets Gall's meaning of "works" Now suppose that there is an addition of a new region to cover or a new product line that is added.  Keeping the system relatively the same and grafting on these additions will necessarily create a more complex system. +
- +
-Howeverequally true is that some systems are implemented at a certain level of complexity and perform the desired function but, then, after the system is put into use for a time, simplifications are found.  This happens frequently in businesses that add dissimilar revenue-generating processes.  Take the hypothetical example of a law firm that seeks to add a revenue stream by created an associated title company.  It is not hard to imagine that the Firm, being conditioned to take extra precautions to avoid malpractice and injury to their law licenses, would set up a fairly complex system based upon their work with other title companies.  However, once the new title company starts to function simplifications may be found as the employees of the new company become more familiar with the system and the needs of their work The cause is that the system was developed by individuals who were not intimately familiar with each and every parameter of the process needed               +
- +
-As Gall's statement is not true in every occurrence, it cannot be law. Much of my critique focuses on Gall's use of the word "works" and that may be seen as simply a semantic issue.  Unfortunately, it is not just semantic; it has operative effect and creates a dichotomy.  Gall's proponent might argue that the meaning is clarified by some other work of his, even in the same work where the "law" is found, and that this somehow "saves" the statement.  Unfortunately, this is incorrect.  If Gall's meaning is obfuscated by the choice of words in the "law" or if deriving their meaning relies on external sources of informationthen his statement fails under the rule of statutory construction that demands that a law be unambiguous If external sources were required then they must be incorporated by reference andif they are notGall's law drops to Gall's Theorem.  Still an admirable achievement but certainly not law.    +
