ScottsdaleBizz, based in beautiful Arizona, provides custom software development solutions for small businesses across Scottsdale, Arizona and across the nation. We have vast experience in building web-based, mobile, and enterprise-level software solutions for small businesses. Software development comes in many forms including web-based, mobile, database, intranet-based, to name a few. As part of the development process, you must take into account how the software will be used, on multiple levels and by different types of users. Software development includes conceptualization, business analysis, and prototyping, along with coding, testing, and deployment, and contrary to popular belief, it’s not a one-and-done lifecycle.
Quite the contrary. Quality software requires periodic modifications, feature enhancements, optimization, and continuous improvement, all of which are part of the Software Development Life Cycle (SDLC). At Scottsdale Bizz, we understand this need and it’s this core belief that separates our company from the sea of other development firms. We also understand that in today’s complex and rapidly changing environment, customized solutions have become a viable business approach for small businesses that want to differentiate themself from their competitors. Enterprise-specific software achieves two major business goals. First, custom software development can increase operational efficiency by 100% or more – we’ve seen it happen. Second, well-designed aggregate reporting tools produce business intelligence (BI) senior management can use to make smart business decisions, eliminating the guesswork while increasing productivity.
