NOC code confusion - 2171 or 2173

[oldenuf]

I work for IT consulting company and my job includes my main duties include discussing with clients collecting user requirements ,design ,build ,testing and implementing solutions for the clients application . my designation is Assistant Consultant . Does 2171 Noc code include actual software development related activities or is it purely analytical role ? Since I am working for a IT consulting /outsourcing firm and not directly with a software development firm is it better to use 2171 ? however since I also perform actual software development activities like coding and testing for the client should I use 2173 instead ?

which code has a better job market ?
