I won’t budge! Without considering behaviors with multiple codes Interpretation : Actors do not engage in sense-making as much as they do in design and negotiation.  They anticipate own role and stance to remain stable. Fundamentals Standards Standardization
Big pockets dictate outcomes! During  the meeting Prior to   the meeting Interpretation : The process is significantly influenced by design contributions from participants, who can expend significant resources for designing parts of the standard under development. This may question openness of the process. Fundamentals Standards Standardization
Design by committee? Not! Interpretation : A significant amount of design may be occurring outside the W3C meetings, and may compromise transparency of the process. Fundamentals Standards Standardization
Design ‘as’ negotiation Interpretation : The overlap between design and negotiation suggests that  Design activities may replace other forms of negotiation behaviors. Fundamentals Standards Standardization Assertion Design is an important element of IT standards
