Building blocks for continuous experimentation

Abstract: Development of software-intensive products and services increasingly occurs by continuously deploying product or service increments, such as new features and enhancements, to customers. Product and service developers need to continuously find out what customers want by direct customer feedback and observation of usage behaviour, rather than indirectly through up-front business analyses. This paper examines the preconditions for setting up an experimentation system for continuous customer experiments. It describes the building blocks required for such a system. An initial model for continuous experimentation is analytically derived from prior work. The model is then matched against empirical case study findings from a startup company and adjusted. Building blocks for a continuous experimentation system and infrastructure are presented. A suitable experimentation system requires at least the ability to release minimum viable products or features with suitable instrumentation, design and manage experiment plans, link experiment results with a product roadmap, and manage a flexible business strategy. The main challenges are proper and rapid design of experiments, advanced instrumentation of software to collect, analyse, and store relevant data, and the integration of experiment results in both the product development cycle and the software development process.

Performance Alignment Work

Abstract: ContextCompanies increasingly strive to adapt to market and ecosystem changes in real time. Gauging and understanding team performance in such changing environments present a major challenge. ObjectiveThis paper aims to understand how software developers experience the continuous adaptation of performance in a modern, highly volatile environment using Lean and Agile software development methodology. This understanding can be used as a basis for guiding formation and maintenance of high-performing teams, to inform performance improvement initiatives, and to improve working conditions for software developers. MethodA qualitative multiple-case study using thematic interviews was conducted with 16 experienced practitioners in five organisations. ResultsWe generated a grounded theory, Performance Alignment Work, showing how software developers experience performance. We found 33 major categories of performance factors and relationships between the factors. A cross-case comparison revealed similarities and differences between different kinds and different sizes of organisations. ConclusionsBased on our study, software teams are engaged in a constant cycle of interpreting their own performance and negotiating its alignment with other stakeholders. While differences across organisational sizes exist, a common set of performance experiences is present despite differences in context variables. Enhancing performance experiences requires integration of soft factors, such as communication, team spirit, team identity, and values, into the overall development process. Our findings suggest a view of software development and software team performance that centres around behavioural and social sciences.
