دانستن شرایط پیرامونی فضای تولید و توسعه نرم افزار کمک شایانی به تحلیل درست و تفکر در ساماندهی آن می‌نماید. مطلب زیر بخشی از شرایط را توصیف می‌نماید:
IT development does not take place in isolation. The purpose of IT is to facilitate the operations of a business. The needs of the business environment drive the way we develop IT.
Current business drivers include:
The On Demand Business:
As businesses are expected to be more adaptable and flexible, so too are the IT systems that enable them.
Business relevance:
Now more than ever, there is a strong focus on IT departments to deliver business value. Software must be business relevant. Miscommunication between business and IT people can lead to projects that, successful from an IT-delivery viewpoint, are deemed business failures.
Cost control:
The days of IT being invested in on the strength of its promises are long gone. IT departments now operate under strong budget constraints and are expected to demonstrate value for money.
Increasing complexity:
Software systems continue to increase in scale and complexity to meet business needs. Techniques that work well for small-scale development do not necessarily scale to enterprise-wide initiatives.
Skills availability:
The sophistication of today’s IT platforms means that specialists’ knowledge is required to deliver software. Many organizations struggle to find sufficient skilled professionals to support their development. In addition, projects often depend on key individuals and suffer significantly if those individuals leave a project or organization.
Changing middleware environment:
Today’s applications are deployed to a huge variety of middleware platforms, and the rate of change in platform technology is showing no sign of slowing up. Businesses want to take advantage of advances in middleware but do not want to repeatedly rewrite their applications.
