• (15) Post “Innovation Proposals” on the Melexis Barrier Reef web portal

• Request an Innovation Voucher (10%FTE) to work on the posted proposal

• Participate to the Sparkling Event• (10) Submit Innovation Project Brief

o Why ? (Initial “desirability”, Details of the problem to overcome: the need, the pain, VoC (internal/external), Light business plan (aligned with corporate strategy))

o What ? (truly novel (i.e. not a simple incremental step), never done before (at least at MLX), top-line oriented, not limited to IC: package, test, fab process, applications)

o Who ? (Team members: core team + needed resources to have the project moving forward…)

o What ? & How ? (Project plan)

o When ? (Project planning (milestones))

o How much ? (Project budget both in time (man-hours) and money (Euro))
