Software Development Process
The software development process, or life cycle (SDLC), is a structure for defining progress. There are a number of development methods which describe approaches to the tasks and objectives involved. These process models began with waterfall methods, which developed in turn into iterative, Agile, and extreme programming (XP) processes.
Typically any software development includes stages of requirement analysis, specifications, software architecture, implementation, testing, documentation, training and support, and maintenance.
In thee internal software projects, this cycle is completed for a version to be used by business and remains steady for a while till business needs new changes. However, software product development in many instances, development is never really completed, as there are numerous releases over time with new features and fixes as customer feedback is received and user needs change more frequently. With new cloud based SaaS products gaining foot in market, the cycles of development have become more agile and product companies are actually doing this shorter as possible to get more customer feedback as fast as possible.
With internal software projects, it is usually seen that CIO or IT heads get the requests for business software needed, which gets checked by them if available off the shelf. This is what drives to make decisions of creating this custom internally for their business OR if a off the shelf software package can be used to meet the needs with minimal or no customization.
In technology startup space, CEO is more of an “idea man” or venture capitalist who hires or partners with a technology specialist to head up development. This is the CTO, or chief technical officer. In practice this is seldom a hands-on team leader but a technical adviser. In today’s development world of IT outsourcing, this is not someone with a vested interest in the technology startup, but a contracted, high-level consultant who can be hired as virtual CTO. The role may become more physical and they may need to bring a full time CTO in house once the product hits market
Platforms & Technology Stack
Today’s software product development can be extremely complex, and may need to run a variety of devices and platforms. Development teams must stick to their methodology to establish and meet requirements, plan system architecture, and coalesce constantly revised code blocks into a working product that satisfies all quality tests. Going at it with a poorly defined process will only lead to failure.
In contrast, an internal project although being a very important requirement from business standpoint, does not necessarily need to support many platforms for user adaptability as most of the users may still be internal to business. Technology and architecture decisions however are equally important, still rank low as preference if compared with product development needs of a technology company.
