Here's some interesting concepts about computer software solutions.
1. 50% (about half) of all software projects fail to meet both customer and developer’s expectations… either the customer is not happy (late, not fully functional or costs too much)... or the developer is not happy and ends up working hundreds of hours to finish what they bid 10 hours.
2. Of the 50% of the ones that are successful.. the critical success factors are:
a. Project Management (management and oversight of the development life cycle.. from concept to development to test to final delivery and support)
b. Clear requirements - either a model, or prototype or screen shots or nicely written English or all of the above that document what is needed.
3. 80% of the software is “visual” and takes 20% of the work effort… while 20% of the software is "non-visual" and takes 80% of the work effort.
4. There is a relationship between these 3 factors (the customer can define ANY 2 but the developer can define the OTHER 1):
a. Schedule (how fast the software is needed)
b. Cost (how much is budgeted for the software)
c. Functionality (all of the function and capability that is desired)
5. Software is never finished…. It is an ongoing investment (usually between 5% and 10% of the gross revenues of a business that depends on information systems). For example, if your business grosses $1M… then you should be spending between $50K and $100K to maintain all hardware, software, networking, development, operations, maintenance and support related to computer solutions.
6. Software is 50% ART and 50% SCIENCE. When building homes with standard materials you have measurable units (2x4 lumber, 4x8 plywood, 16Gage wire, 110V electricity, ¾ inch bolt with National Course threads). Software uses a logical-pallet with dozens small re-usable functions that must be assembled by a person who is both an artist (shares the vision and requirements of what is needed) and a scientist (software engineer with a knack for logic, process, syntax coding and technology).
7. Computer programmers are eternal optimists that constantly believe “the next time they try it… the program will be perfect…”
Seven Sisters of Software Excellence:
1. Affordability - is it priced right compared to the competition and the value-received?
2. Scalability - can it easily grow to handle more volume and more functions?
3. Performance - does it perform well and at what levels of volume?
4. Feature - does it provide all of the needed business features?
5. Function - is it easy to use, navigate, interface, interact (user friendly), backup and restore?
6. Service - are upgrades, patches and enhancements provided to keep the product current?
7. Support - is there a fast and effective customer/product/tech support service available to resolve issues?
