Software development life cycle (SDLC) models have varying phases and advantages and disadvantages. A software project can be complex and costly, with a budget ranging from $3000 to $120,000. It is important to know the advantages and disadvantages of SDLC models before you choose one. If you’re unsure about which one to use, consult an expert. The advantages and disadvantages of each model will be outlined in the next paragraphs.
Big Bang Model: The Big Bang Model is the most simplistic SDLC model. This process begins without any prior planning or organization. Instead, it begins with a budget and time frame. Software engineers don’t spend a lot of time planning this process. It is suitable for small and medium-sized projects. The Big Bang Model requires less documentation and is quicker for end-users. Other models exist in the industry, but Big Bang is the most common.
Spiral Model: This model is a variation of the Waterfall model. It includes characteristics of both Waterfall and Iterative methods. It includes risk analysis. The Spiral model is more suited for larger-scale software systems. This model also allows for flexibility. While a waterfall model is a great way to develop a new application, an Spiral model is a better option for a more complicated one.
