Özet

ÖZET Geleneksel organizasyon ve yönetim teknikleri, büyük ölçekli ve modern teknolojilerin kullanıldığı günümüzün inşaat projelerinin istenilen süre, maliyet ve teknik özelliklerle gerçekleştirilmesinde yetersiz kalır. Bu da proje yönetimini destekleyen ve kontrolü kolaylaştıran yeni sistemlerin kullanılmasını zorunlu kılar. Özellikle büyük projelerde bilgi ve karar akış sistemi proje yönetimini kolaylaştıran ve etkinleştiren çok önemli bir faktör olarak ortaya çıkmaktadır ve sistem her projenin kapsamına, organizasyon yapısına ve büyüklüğüne göre farklılık göstermektedir. Bu çalışmada İzmit Entegre Çevre Projesi'ndeki bilgi ve karar akış sistemi ortaya konulmuş ve sistemin etkinliği değerlendirilmiştir. 1. Bölümde; inşaat projelerinin kendilerine özgü özelliklerinden ötürü bilgi ve karar akış sistemlerinin kurulması ve etkin olarak çalışması gerekliliği vurgulanmış ve inşaat projelerinin kendilerine has özellikleri maddeleştirilmiştir. 2. Bölümde, İzmit Entegre Çevre Projesi'nin kapsamı içerdiği tesislerle ilgili bilgilerle açıklanmış, projenin fizibilitesi her tesis için sosyal ve sağlık açısından sağladığı yararlar ve mali analizlerle ortaya konulmuş, projenin ihalesi ile ilgili bilgiler kronolojik olarak sıralanmış, bilgi ve karar akış sistemini biçimlendiren sorumluluklar üzerinde durularak sözleşme koşullan ve organizasyon konulan ile ilgili açıklamalara yer verilmiştir. 3. Bölümde; projede bilgi ve karar akış sisteminin nasıl oluşturulduğu, sistemi biçimlendiren organizasyon ve görev tanımlan açıklanmıştır. Projede yüklenici durumundaki konsorsiyumun ortaklarından Vinsan A.Ş.'nin planlama departmanında hazırlanan ve projede bilgi akışını sağlayan raporların ne amaçla, hangi içerikle, nasıl hazırlandığı ve gönderildiği yerlerle ilgili bilgiler akış şemalarıyla anlatılmıştır. Ayrıca projede kararların alındığı toplantıların ne amaçla, hangi sıklıkla, kimlerin katılımıyla yapıldığı ve bilgi akışını sağlayan raporların toplantılarda nasıl kullanıldığı ve karar akışının nasıl işlediği ortaya konulmuştur. Sonuç ve Öneriler Bölümünde; sistemin etkinliğinin değerlendirilmesi için gerekli olan kriterler ortaya konulmuş ve bu kriterlere göre sistem değerlendirilmiştir. Bu değerlendirme yapılırken konu birçok kaynaktan araştırılmış ve bir bilgi ve karar akış sisteminde bulunması gereken nitelikler ve dokümanlar eldeki sistemle karşılaştırılmıştır. Ayrıca yazarın raporlarla ilgili önerileri ve bu önerilerin projenin kontrolüne getirdiği kolaylıklar maddeleştirilmiştir. vn
