Software Requirements, Kierkegaard ve Modernizmin Çöküşü

YAZILIM MÜHENDİSLİĞİNE GİRİŞ:
ignorance is bliss

Giriş.. Project,
Software development,
COTS (Commercial off-the-shelf),
Open Source..

  Problems create the down-growing triangle of:
        Needs
    Features
Requirements

Gelişme.. Brian Arthur ,
Diminishing Returns "..azalıyordu durmadan..",
Six Sigma (BS),
QFD -> interesting..

WHY



Soluklan.. Russell Ackoff.
Systems through purposes, "-" means `do not possess purpose`, "+" means the opposite:

Parts	Whole
-	-	Mechanic
-	+	Animistic
+	+	Social
+	-	Ecological

features.. Priority, Effort, Risk.. 3 syndromes of elicitation:
"Yes, but" syndrome
"Undiscovered Requirements" syndrome
"User and the Developer" syndrome

Sıkı Dur!!.. Dreyfus Model: "Dediğim gibi yap, yaptığımı yapma" syndrome..
Jared Diamond and Guns, Germs and Steel..

Sistem Dinamiği,
Oyun Teorisi a.k.a. Game Theory(from Stanford Encyclopedia of Philosophy),
SEÇİNİZ!! Borda Count, Kenneth Arrow and his Impossibility Theorem :

In short, no "fair" voting system can satisfy these three criteria:
* If every voter prefers X over Y, then the group prefers X over Y.
* If every voter prefers X over Y, then adding Z to the slate won't change the group's preference of X over Y.
* There is no dictator.


Never underestimate nor overestimate the power of Pareto Principle (also known as the 20-80 theorem..)

Caution: Strategy-proof voting does not exist!!..
