Troubleshooting to diagnose computer problems

In a support service for computing devices or software (or other service), a determination is made based on an incident report that additional data is needed. A first template is chosen from a set of templates and that chosen first template is customized for the particular incident to create a data collection plan. The data collection plan includes a set of data collection items. The data collection plan is forwarded to a user client device associated with the incident report. At the user client device, a user can choose to proceed with all or a subset of the data collection items. Data is then collected for the selected data collection items. The user is then provided with the opportunity to select which of the collected data to upload back to the support service. The collected data is then uploaded, and the incident status is updated and made available.
