Nowadays, it becomes very important to know the level of
institutionalization and as a result what improvements they can make for
organizations. Though there are many conceptual studies of institutionalization
in the literature, there is no study based on numerical methods that can
provide a foresight about institutionalization. In this paper, a new model has
been proposed by determining concepts that are effective on institutionalization
from literature and expert opinions. Firstly, the relationships between the
concepts are taken from the experts linguistically. Linguistic expressions are
converted to numerical values using the center of gravity method (COG) used in fuzzy
logic applications. Then, three different scenarios were investigated by using
the Fuzzy Cognitive Maps (FCMs) algorithm and the future states of the concepts
were determined and interpreted. In the first scenario, an organization with
poorly managed organizational concepts was considered. The institutionalization
tendency in this organization has reached to 0,027 value which is the
estimation calculated by FCM algorithm in the future. The second scenario and
the third scenario represents a midlevel and good organization respectively.
Institutionalization tendency values were 0.97 for the second and third
scenarios. However, when the number of iterations representing the time period
is examined, it is seen that the organization thought in the third scenario has
reached this value before 9 iterations. This is because the organization in the
third scenario is well managed in the current situation. With the developed
model, the most effective concepts on institutionalization were also
identified. It has been determined that the most important concepts affecting
institutionalization are process management, information management and
strategic management. Compared to the literature, the results seem to be
consistent.

Kurumsallaşma analizi için bulanık bilişsel haritalar temelli yeni bir yaklaşım

Kurumsallaşma, organizasyondaki
yöneticilere ve çalışanlara bağlı olmadan, tüm süreçlerin şeffaf ve sistematik
olarak yürütülmesini ifade eder.

Kurumsallaşmanın mükemmeliyeti organizasyonun misyon, vizyon ve stratejik
hedeflerine paralel yönde seyreden ticari faaliyetlerle sağlanabilir.
Kurumsallaşmanın organizasyon içerisinde benimsenememesi organizasyonların uzun
süreli yaşam döngüsünü engellemektedir. Bu nedenle, organizasyonların
kurumsallaşma seviyelerini takip edebileceği ve bu takip sonucunda hangi
iyileştirmeleri yapabilecekleri konusu çok önemli hale gelmektedir. Literatürde
kurumsallaşmanın kavramsal olarak incelendiği birçok çalışma olmasına rağmen
ileriye yönelik bir öngörü elde edilebilen sayısal yöntemlere dayalı bir
çalışmaya rastlanmamıştır. Bu çalışmada, kurumsallaşma üzerinde etkili olan
konseptler literatür ve uzman görüşleriyle belirlenerek yeni bir model
önerilmiştir. Öncelikle uzmanlardan konseptler arasındaki ilişkiler
dilsel
olarak alınmıştır. Dilsel ifadeler, bulanık mantık uygulamalarında kullanılan
ağırlık merkezi yöntemiyle sayısal değerlere dönüştürülmüştür. Daha sonra,
Bulanık Bilişsel Haritalar(BBH) algoritması kullanılarak 3 farklı senaryo
incelenmiş ve konseptlerin gelecekteki durumları tespit edilip, yorumlanmıştır.
Geliştirilen model ile aynı zamanda kurumsallaşma üzerindeki en etkili
konseptler ve geleceğe yönelik öngörüler de belirlenmiştir.
