Read back on what was common practice, or interesting events related to the corporation or faction. Steal copies of the data to sell to other corporations, leave a digital paper trail of it. Or don't, if you have the right skills. Endless possibilities for deeper espionage and preservation of the history of the game.
I think that the grid needs to be useful for everyday people. From Gangers to PR and HR and CorpSec and Production and more. By this I mean that no skills required usefulness. Remove a lot of the whiteboards and e-notes and the like currently used and replace with the grid with access control that either runs at the default or, if the organization is smart, whatever the decker they pay can manage.
Including 'grids'. The Public grid most use. The NLM grid. The VS and PRI grids. The WJF grid. Access limited by location plus whatever default or decker driven access control may exist.
Because it's useful you actually have useful data there. Relevant up to date data. Some of it maybe even created as a part of those new topside quests and GMs and other systems but mostly by players. Now hacking it has value beyond drawing dicks and seven year old data that was only there because a rare decker felt generous enough to create content for other deckers.
Because it's an organization grid, you have to be there to use it. Get players to their workplaces a bit more maybe. And it means hacking an organization's grid can involve more people. Distractions. Security for the decker. A wheelman. And if they are local maybe you can tie in cool things to it like cameras and doors at that site. Which gives more reasons for a team to hack it because it's more useful!
