Do Software Factories live up to the Promise? Chris Lowndes Avanade Software project delivery is under ever increasing pressure Software industrialisation is the new paradigm to address this Numerous forces are acting against factory adoption Architects and thought leaders are the key to overcoming these forces Overview Software project delivery is under ever increasing pressure Software industrialisation is the new paradigm to address this Numerous forces are acting against factory adoption Architects and thought leaders are the key to overcoming these forces Overview Evolution in Business Systems Batch Processing Terminal/Host Distributed Computing 1950 1970 1990 2010 Core Business Applications Integrated Business Applications Early Client Server Web Aware SOA Evolution in Software Development Task-centric Development Application-centric, Waterfall Development Distributed, Agile Development 1950 1970 1990 2010 Knowledge Worker Led Web Applications SOA IT Department Led Vendor Led Enterprise Rigour CIO drive to continually deliver more for less Budgets under downward pressure Outsourcing to ring-fence costs Off shoring to reduce costs Pace of change increasing Quality expectations remain constant Ever increasing pressure Software project delivery is under ever increasing pressure Software industrialisation is the new paradigm to address this Numerous forces are acting against factory adoption Architects and thought leaders are the key to overcoming these forces Overview We need to promote the state of the software development art Moving to increasingly higher levels of abstraction has been a trend for some time More expressive model-driven techniques and tools have emerged. However, most (based on UML) struggle to convey complex implementation details Software factories and the domain-specific languages they employ can help to bridge the gap between problem model and the programming language The need for change Paradigm Shift Inception Optimization Maturity Procedural Object Orientation Industrialisation Value Time Today (After Kuhn, 1970) Software Factory Usage Case Study (1) Business Problem Global investment bank Live derivatives trading Expose sensitive LOB processes over web Time-sensitive transactions Critical dealer control Eight-month delivery window High degree of change expected Solution SOA trading platform High-performance web client Real-time smart blotter Factory approach and agile methods enabled: Accelerated build Consistency Ease of change Case Study (1) - Trading System Schematic Case Study (1) - Factory Techniques Employed Typical SOA Landscape Service Consumer Applications Foundation Services Aggregator Services Orders Customers Items Case Study (1) – Lessons Learnt Gain project stakeholder buy-in to the software factory approach Front load delivery plan to allow factory preparation and testing Include capability development as
