1 Facing the Challenges of Teaching Requirements Engineering Roxana Portugal, Priscila Engiel, Joanna Pivatelli, Julio Cesar Sampaio do Prado Leite Departamento de Informática, Pontifícia Universidade Católica do Rio de Janeiro Software Engineering Education and Training - ICSE 2016 Austin, May 19

2 Problems Teaching with perfect problem descriptions No interaction with real clients and problems RE tasks not used in practical experiences

3 Approach Value Develop critical thinking - The Startup what I need? eliciting where when what why how how much V&V when who how much my client needs? - The RE Builder team work modelling analysis management

4 Startups

6 Startups facts - The majority of the startups do not survive the first two years [1] issues, specially related to requirement processes, are key to this high failure rate [2] - In a startup context, users and/or customers are often unknown [3] - Startups usually build a minimum viable product (MVP) [4] One of the common mistakes with this approach is to understand what minimal means [5] [1] Software development in startup companies: Thegreenfield startup model [2] From knowing nothing to knowing a little: Experiences gained from process improvement in a startup company [3] The Lean Startup: How Today s Entrepreneurs Use Continuous Innovation to Create Radically Successful Businesses [4] The role of value proposition and value co-production in new internet startups: How new venture e-businesses achieve competitive advantage [5] Mvp explained: A systematic mapping study on the definitions of minimal viable product

14 Conclusion we tackle the elicitation challenge students have to learn that requirements are not there in written form, they have to be elicited in the building process awareness that, in real projects there are several stakeholders, so large groups are frequent.
