The objective of Social experience design is to deliver solutions that match 'stakeholder' needs. This includes needs of the people developing the software. #SX has a sustainability-first focus and instead of "FOSS projects" refers to #SOSS initiatives. Sustainable open social systems / software / solution / services. Projects that address the relevant aspect of their #FSDL, the end-to-end Free software development lifecycle.
To add #social layers, beyond #technosphere.
