pioneer Partners, Inc. is being sued by a buyer who bought a commercial building originally owned and listed by Pioneer. The buyer is suing Pioneer because they believe that the building has a faulty fire suppression system.

Pioneer acted in good faith and obtained an inspector's report that described the building as having a good and functioning fire suppression system prior to selling the building which it provided to the buyer before the transaction was finalized.

Pioneer retains counsel who recommends utilizing the discovery process to ensure that they have all of the evidence they will need at trial. Specifically, they think that they will need to obtain the testimony of key witness and obtain documents from the buyer and inspector relating to this deal.

1. Please explain what discovery is and identify type of discovery Pioneer should conduct under these facts?
