Project management

Sprint

Definition

Short development cycle (usually 1 to 4 weeks) in an agile methodology. Each sprint has a specific goal and delivers a functional product increment.

Detailed explanation

The European eIDAS regulation (910/2014) defines 3 levels of electronic signature. Simple: a click or checkbox (limited value). Advanced: identification of the author plus integrity control (SMS or email validation). Qualified: advanced signature plus a qualified certificate issued by a trusted third party, with legal value equivalent to a handwritten signature. For a freelancer, the advanced level is sufficient in 95% of cases. Benefits: signing in 2 minutes from anywhere, tamper-proof timestamping, automatic archiving, no scan, print or re-scan.

Concrete example

A 3,500 EUR coaching contract signed with advanced eIDAS from the client's phone in 90 seconds, with timestamping and proof of receipt, has the same legal value as a paper signature.

Common mistake

Using a simple signature (scanned PDF sent back by email) for a contract above 5,000 EUR. If the client disputes it, the absence of certified timestamping and integrity control makes the proof fragile.
