Personal independence payment

I started my claim back on the 15th of jan this year, I got a call on the 22nd March asking if I can handle a lump sum or if I would want it spread out over the months, I said I was fine with a lump sum of back payment. He said I would receive a letter within 10 working days (2 weeks) letting me know of the decision of my pip claim. He mentioned he was an assessor. Does anyone know what this means, perhaps it’s a sign I may be getting awarded?
