   § Through this work we have come to value:
   “Individuals and interactions over processes and tools
   Working software over comprehensive documentation
   Customer collaboration over contract negotiation
   Responding to change over following a plan “
   § That is, while there is value in the items on the right, we value the items on
   the left more.
   Agile Manifesto

   § Product development where a software company is developing a small or
   medium-sized product for sale.
   § Several software products and apps nowadays are small or medium-sized;
   therefore, they are developed using an agile approach
   § Custom system development within an organization, where there is a clear
   commitment from the customer to become involved in the development
   process and where there are few external rules and regulations that affect
   the software.

   § The product is broken down into a set of manageable and understandable
   chunks.
   § Unstable requirements do not hold up progress.
   § The whole team have visibility of everything and consequently team
   communication is improved.
   § Customers see on-time delivery of increments and gain feedback on how
   the product works.

   § The informality of agile development is incompatible with the legal approach
   to contract definition (requirement specification) that is commonly used
   in large companies.
   § Agile methods are most appropriate for new software development rather
   than software maintenance (documentation). Yet the majority of software
   costs in large companies come from maintaining their existing software
   systems.
   § Agile methods are designed for small co-located teams yet much software
   development now involves worldwide distributed teams.
