SİSTEM GELİŞTİRME YAŞAM DÖNGÜSÜ: TEORİDEN PRATİĞE SİSTEMATİK PROBLEM ÇÖZME YAKLAŞIMI

Öz

Hızla değişen pazar dinamikleri ve karmaşıklaşan iş süreçleri, yöneticilerin klasik yöntemlerle karar almasını ve sorunları çözmesini yetersiz kılmaktadır. İşletmeler günümüzde anlık operasyonel hatalardan ziyade; süreç optimizasyonu, veri yönetimi ve stratejik belirsizlik gibi çok katmanlı kurumsal problemlerle mücadele etmektedir. Bu çalışma, söz konusu karmaşık problemlerin çözümünde bütüncül bir bakış açısı sunan Sistem Yaklaşımı ve Sistem Geliştirme Yaşam Döngüsü (SGYD) metodolojisini entegre eden bir yol haritası sunmaktadır. Çalışma kapsamında öncelikle Genel Sistem Teorisi’nin kavramsal çerçevesi çizilmiş; donanım, yazılım, veri, insan ve süreç bileşenlerini, "Amaç ve Hedefler" doğrultusunda birleştiren modern Bilişim Sistemleri yapısı irdelenmiştir. Ayrıca geleneksel Yönetim Bilişim Sistemleri piramidi, İş Zekası ve İş Analitiği yetkinlikleriyle genişletilerek güncel bir perspektifle yeniden modellenmiştir. Çalışmanın uygulama boyutunda ise SGYD'nin aşamaları (Planlama, Analiz, Tasarım, Gerçekleştirme ve Bakım); soyut işletme problemlerinin somut ve sürdürülebilir bilişim çözümlerine dönüştürülmesinde bir kılavuz olarak ele alınmıştır. SGYD’nin sadece bir yazılım üretim süreci değil, aynı zamanda stratejik bir problem çözme metodolojisi olduğu vurgulanan bu çalışmada; projelerin başarısızlık nedenleri, veri kalitesi ve kapsam yönetimi gibi kritik faktörler analiz edilmiştir. Sonuç olarak, bu sistematik yaklaşımın işletmelerin operasyonel verimliliğini artırmada, hata riskini minimize etmede ve rekabet avantajı sağlamada nasıl etkin bir araç olarak kullanılabileceği ortaya konulmuştur.

SYSTEM DEVELOPMENT LIFE CYCLE: A SYSTEMATIC PROBLEM-SOLVING APPROACH FROM THEORY TO PRACTICE

Öz

Rapidly changing market dynamics and increasingly complex business processes render classical decision-making and problem-solving methods insufficient for managers. Today, businesses grapple with multi-layered corporate problems such as process optimization, data management, and strategic uncertainty, rather than merely instantaneous operational errors. This study presents a roadmap integrating the Systems Approach and the Systems Development Life Cycle (SDLC) methodology, offering a holistic perspective for solving these complex problems. First, the conceptual framework of General Systems Theory is outlined; subsequently, the modern Information Systems structure, which unites hardware, software, data, people, and process components under the guidance of "Goals and Objectives," is examined. Furthermore, the traditional Management Information Systems pyramid has been remodeled from a contemporary perspective by extending it with Business Intelligence and Business Analytics capabilities. Regarding the application dimension, the phases of the SDLC (Planning, Analysis, Design, Implementation, and Maintenance) are addressed as a guide for transforming abstract business problems into concrete and sustainable IT solutions. Emphasizing that the SDLC is not merely a software production process but also a strategic problem-solving methodology, this study analyzes critical factors such as reasons for project failure, data quality, and scope management. In conclusion, the study demonstrates how this systematic approach can be utilized as an effective tool for increasing operational efficiency, minimizing error risks, and ensuring competitive advantage in businesses
