Software engineering literature describes several decision-making techniques for architectural design. However, the impact of the experience of those who use these techniques on their efficacy has been little explored.

We experimented with 24 IT practitioners in order to evaluate the impact of the experience of software architecture decision-making team members on the efficacy of TaSPeR (Tactics Selection Poker), a technique that supports architectural design decisions (inspired in the Planning Poker technique).

This research, led by Juan P. Brito, reveal that for teams with more experienced members the use of TaSPeR turned out to be harmful for the selection of software architecture tactics, in contrast to the more experienced teams, for which the use of TaSPeR was quite beneficial. Other key findings are discussed in the article.
