Aspects include a method, a system and a computer program product. The method includes identifying, on an electronic platform providing for an exchange of messages among multiple participants, at least one open issue to be resolved. Data is collected from the exchanged messages to determine a participation interaction parameter and a solution quality parameter associated with at least one open issue. The participation interaction parameter includes an accountability dynamic factor and collaboration dynamic factor and the solution quality parameter includes a velocity factor, a dormancy factor, and an extinction factor. When a sum of the participation interaction parameter and the solution quality parameter is below a threshold value, at least one open issue participant is invited to the electronic platform. It is also determined when the at least one open issue becomes a closed issue.
