In [[software development]], '''Smallsmall Mattermatter of Programmingprogramming''' ('''SMOP''') or '''Simplesimple Mattermatter of Programmingprogramming''' is a phrase used to ironically indicate that a suggested feature or design change would in fact require a great deal of effort; it often implies that the person proposing the feature underestimates its cost. Such underestimated costs are common during [[Cost estimation in software engineering|cost estimation]], particularly near the beginning of a project. The [[Jargon File]] describes an SMOP<ref>[http://www.catb.org/jargon/html/S/SMOP.html Simple Matter of Programming] ([[Jargon File]], version 4.4.7)</ref> as:
:#A piece of code, not yet written, whose anticipated length is significantly greater than its complexity. Used to refer to a program that could obviously be written, but is not worth the trouble. Also used ironically to imply that a difficult problem can be easily solved because a program can be written to do it; the irony is that it is very clear that writing such a program will be a great deal of work. “It's easy to enhance a FORTRAN compiler to compile COBOL as well; it's just a SMOP.”
Line 6:
SMOP was among the "games" described in an article as paralleling the ''[[Games People Play (book)|Games People Play]]'' identified by Dr. [[Eric Berne]] in the field of self-help psychology.<ref>{{Citation | last = Shedley | first = Ethan I. | title = [[Big System Games]] | magazine = [[Datamation]] | volume = 17 | issue = 7 | pages = 22–25 | publisher = Technical Publishing Company, 1301 South Grove Ave., Barrington, Illinois 60010 | date = April 1, 1971 }}</ref> The game essentially consists of proposing seemingly simple adjustments to a design, leading to unexpected consequences and delays.
'''Simple matter of software''' or '''Smallsmall matter of software''' is occasionally used in the same manner. However, it is also used without irony<ref>{{cite journal |title= ONDI – The ON-line Device Interface |journal= Circuit Cellar INK The computer Applications Journal |author= John Dybowski |issue= 18 |date= January 1991 |page= 16 |url= http://www.pestingers.net/pdfs/other-computers/circuit-cellar/1990/circuit-cellar-018.pdf |quote= This turns out to be an almost trivial exercise, mainly because the computer is used to compute and the controller to control.

This usage is often invoked when the speaker wants to contrast the implied ease of software changes with the suggested greater difficulty of making a hardware change or a change to an [[Standardization|industry standard]]. This non-ironic usage is more often invoked by [[senior management]] and [[Hardware architect|hardware engineers]], than it is by software engineers.{{Citation needed|date=August 2017}}
