Construction of the 5000 fibre Dark Energy Spectroscopic Instrument (DESI) is well underway and on schedule to start the DESI surveys towards the end of next year. I will describe DESI, the surveys that will be under taken with DESI and the main science goals of the collaboration. The huge number of redshifts in these surveys offer the prospect of cosmological constraints from large scale structure with unprecedented small statistical errors. The formidable challenge is to make the systematic errors even smaller. With particular emphasis on the incomplete redshift measurements Bright Galaxy Survey (BGS), I will illustrate how realistic mock catalogues are being used to quantify systematics and assess correction techniques.
