Sources of influence
Apart from direct control, you can have influence within your ecosystem. The actual influence can be derived from ‘hard’ factors like ownership and governance of your company, economic relation with stakeholder(s) or your legal/political power or more ‘soft’ aspects like your vision, trustworthiness and credibility, importance and strength of the (emotional) relation or the public opinion.
Impact of influence
These aspects influence how you can stimulate others to take sustainable topics and issues into account. Other aspects that affect the sphere of influence are physical distance and strength or lenght of the relation.
