of software innovation The challenges of systems and software development

Systems and software development businesses face many challenges. Systems are complex, and there is pressure to deliver higher quality faster and cheaper. The prevalence of embedded soft- ware in hardware systems like an engine man- agement system or the avionics in an aircraft, means that software is the competitive business advantage. But in order for software to become a business advantage, it must be robust, correct and complete.

Software developers are expected to deliver mir- acles coding manually with reduced resources. As a result, the software development cycle is slow Successful Failed and inflexible. Developers waste valuable time 28% 23% fixing low-level problems instead of focusing on the architecture and design of the solution. Project milestones are missed and product qual- ity suffers.

‘Software development’ has been recognized as a discipline with many problems. According to the Standish Group International, Inc., in 2000, 23 Challenged percent of software development projects failed, 49% while 49 percent were “challenged” - meaning Figure 1. The results of software develop- they were late, over-budget, or delivered insuffi- ment projects in 2000, according to cient functionality. Standish Group International, Inc.

Another challenge faced by many companies is the ‘barrier’ between systems engineers produc- ing system specifications and designs, and soft- ware developers creating detailed designs and implementing software components. Often these teams use different tools and techniques, leading to communication difficulties that result in misunderstandings that can be expensive to find and fix.

Companies risk the loss of competitive advan- tage and market share.

Businesses need an alternative to manual, frag- mented development methods, because they fail to meet the cost, quality and time-to-market demands of today’s economy. Telelogic TAU® Generation2 lets you take the next step

About MDA MDA helps companies tackle the rapidly changing world of software development where new stan- dards and technologies constantly appear. MDA is an OMG initiative, with the objective of ensuring that organizations’ information sys- tems will be able to adapt to new hardware and software platforms by separating the logic behind a specification from its implementa- tion. MDA improves application portability, interoperability, plat- form independence, and develop- er productivity.

About TTCN TTCN (Testing and Test Control Notation) is a globally adopted standard test language main- tained by ETSI (European Tele- communications Standards Ins- titute). In its recently ratified third generation, TTCN-3, it is a modern and flexible language for specify- ing many types of system tests TAU/Developer TAU/Tester over a wide variety of interfaces. Typical areas of application are for software developers for test engineers systems testing, interoperability testing, protocol testing, service testing, module testing, etc. The platform independence and spe- cific test capabilities of TTCN have made it a much used language for defining official test suites for many communication systems, including GSM, 3G and Bluetooth.

Advanced systems and software develop- ment is a complicated process that involves many different types of expertise and one tool does not meet everyone’s exact needs. Consequently, the TAU Generation2 products are role-based and include different levels of functionality targeted to different user groups. At the same time, they are all built on the same platform and offer identical user inter- faces, which minimizes the learning curve and accelerates deployment of the The TAU family system.

Uniquely, with TAU/Architect, system engineers can specify not only the struc- ture, but also the behavior of the system under development. In addition, the specifications can be simulated to verify and validate the system and demonstrate its behavior to end-users and other stake-holders at an early stage.

For software projects, the value of having a common notation – UML – for specification and development improves communication between teams and increases organizational efficiency.
