When developing a collection, I break out all styles into "fabric programs". This way I can make sure I am combining fabrics and placing similar styles with the same vendor for better costing and less quality/color inconsistencies.
Line sheets are used to present design and get a good feel of the delivery flow. But they often fail to give a clear picture of similar styles/fabrication and how many styles are being placed at each vendor. I developed these STYLE TRACKERS each season for better communication.
I used the style trackers when REVIEWING AND COMPARING BIDS and PRESENTING COST OPTIONS TO THE MERCHANDISING TEAM. Then after final vendor and order placement, I used the same trackers as WIPs to keep track of lab dips, submits, sample status and any updates. This allowed me to ensure we stayed on schedule for delivery.
