Several socio-economic trends are generating unparalleled increases in the volume, variety, velocity and complexity of software-intensive products. One of these is people’s desire for personalised products. Suppliers are responding with different approaches to mass customization, but it is placing considerable strain on software designers. The challenge is to build innovative digital products and to create product development processes that can be adapted to meet the demands for evolving sets of inter-dependent requirements and features. One solution is the development of a capability to manage the identification, selection and deployment of reusable requirements and features on a large scale. However, this is far from straightforward and in practice reuse efforts range from operational, ad-hoc and short-term to strategic, planned and long-term, from code to requirements.
This tutorial presents and compares two different requirements-led approaches. The first approach deals with requirements reuse and reusability in the context of product line engineering. The second approach deals with requirements reuse and reusability in the context of case-based reasoning (invented in Artificial Intelligence). Both approaches have different key properties and trade-offs between the costs of making software artefacts reusable and the benefits of reusing them. To aid large-scale development we have proposed a Feature-Similarity Model, which draws on both approaches to facilitate discovering requirements relationships using similarity metrics. A Feature-Similarity Model also helps with the evolution of a product line, since new requirements can be introduced first into a case base and then gradually included into a product line representation.

Rapid prototyping is an effective and efficient way of requirements validation to avoid introducing errors in the early stage of software development. However, manually developing a prototype of a software system requires additional efforts, which would increase the overall cost of software development. This half-day tutorial introduces attendees to an approach with a CASE tool named RM2PT, which can be used for requirements modeling and analysis in UML and automatically generating MVC prototypes from requirements models. By investigating the executions of use cases in the generated prototypes, the stakeholders can easily check whether the requirements reflect their real needs. Moreover, requirements inconsistency can be automatically detected and further fixed through the provided features of the generated prototype. Participants will be given the chance to use RM2PT with the selected case studies, and learn how RM2PT has been and can be applied to real-world projects.

Machine Learning (ML) algorithms and techniques are rapidly becoming an integral part of many types of business systems and applications. Despite this ever increasing interest and advances, many businesses still struggle to identify how to use ML to take advantage of their data. Conceptual modeling, as cornerstone of requirements engineering, is seen to offer considerable value in tackling those difficulties and achieving effective design and implementation of ML solutions.
This tutorial introduces a conceptual modeling framework1 for building ML solutions in business organizations. Using a goal-driven approach, business goals are refined until relevant decisions are identified. Decisions are refined into analytical questions. ML solutions to analytical questions are identified with help of catalogues of ML algorithms. Data preparation tasks required for each type of algorithm are also identified. By linking enterprise strategies to ML algorithms and data preparation activities, the framework provides a comprehensive abstraction of ML applications in a given domain. The framework also provides support for the development of solution patterns for common ML applications such as fraud detection. The tutorial includes a hands-on exercise for participants to become familiar with the framework through experiential learning.

Software needs to satisfy a range of security, privacy, and usability requirements. Eliciting them entails using design techniques both within and outside Requirements Engineering, together with tool-support which can analyse and make sense of requirements and other design concepts as early stage designs evolve. This one-day tutorial introduces participants to CAIRIS, and how it can be used to engineer requirements for usable and secure software. Participants will be given the chance to use CAIRIS with selected usability and security design techniques, and learn how CAIRIS has and can be deployed in real-world projects.
