What do you like best?
Cloud-based, the login-and-go functionality is what I use the most. Being able to edit a slide and/or the narration without disrupting the entire presentation, and have those updates flow into the existing URL. (ie: no file manipulations needed!). Viewing statistics are very good.
What do you dislike?
The authoring tools are outdated and take a long time to really polish and setup animation timings, video syncs, etc. (although still better than other methods, this can still be significantly enhanced). The mobile player (HTML5) is terrible, and they are really late to improve that given the death of Flash and how most browsers will automatically pull the not-so-great HTML5 player. They did recently improve the resolution quality of the slides in the HTML5 player, and they have plans to improve all of these areas, hopefully by Q1-Q2 2018.
Recommendations to others considering the product
There is so many things you can do with Brainshark. Make sure you properly define your goals, and reamin focused on deploying those elements. This can be especially important with elearning or even sales force usage of content -- what metrics do you need, when, and what kind of feedback/viewing info is needed by sales, etc... Having a solid plan in place will ensure you propoerly organize the content and setup the right viewing reports and frequencies to measure your progress and content effectiveness.
Also, work with others to showcase the range of capabilities. For example, my particular deployment focuses on event replays and customer-facing presentations to share with the selling and user communities. In sharing with other departments, they will soon deploy the sales enablement/coaching capabilities. Brainshark has been great to work with our various departmental and evolving needs.
What business problems are you solving with the product? What benefits have you realized?
Replicating event session replays to our users, and broadcasting exec-level presentations to the selling community (and users too). It gives great analytics for what content is being consumed, and the viewing details inside the content, and give guidance as to what's important and what is compelling.
