Ricoh has ensured that its business innovation practices stem from customer feedback and inputs. There are four ways in which customer insights have been leveraged for the same. First of all technology centre workshops have been organized. The European Technology Advisory Conference has been designed as the cornerstone of such events. Even non- customers are invited to participate in the e-TAC. Innovation focus groups have been developed where groups of customers with common interests have been administered focus group discussions. Collaborative innovation programmes have been launched as this has enabled Ricoh to move away from linear processes to the multi-dimensional ones.
