Google eSIM

Designing for eSIM is already challenging given the highly technical nature of the problem space, but interviews with core team members indicated some additional hurdles.

• The previous designs had been mis-interpreted at implementation leading to a cross-PA conflict
• Project milestones lacked clarity and ownership
• Recent turnover on the team meant that requirements documentation (though dense) was inconsistent and sparse
• Completion required getting signoff by the GSMA — a regulatory body establishing the parameters within which eSIM will continue to exist for generations to come
