Software Architecture for large/critical applications

Software Architecture provides a blue print for developing a system and plays a vital role in addressing quality related aspects such as performance, security, scalability etc. [1]. Architecture of a software system has to ensure that design is able to support all requirements as well as able to incorporate any changes requested by the customer. This paper discusses the role of architecture and design on project failure rate and also suggests the steps that need to be added in architecture and design in order to cope up with changes in business requirements and evolution of technology to avoid such failures.
