| tools, methodologies to analyze, design, optimize processes. | Business Process Management |
| Enabler of organization change | Business Process Management |
| Steps in BPM | IADIM Identify processes for change, analyze existing processes, design new process, implement new process, measure continuously |
| rectangle in business process | action |
| diamond in business process model | decision |
| arrow in business process model | sequence of action |
| Activities to implement new information system | golden triangle: on time, within budget, with quality |
| Sometimes called "methodology" | System Development Process |
| When inflexible, system development process is called | inflexible |
| This slows development of new IS, but allows to share what and how implemented | documentation |
| proposal to use IS to solve problem | preliminary study |
| cost benefit analysis, initial schedule, charter or project agreement | feasibility study |
| defining the broad problem and identifying causes | systems analysis |
| planning new system | system design |
| what the user sees, defines database | logical design |
| database, program specifications, hardware | physical design |
| marclogic | noSQL Hadoop |
| physical design specs translated into software | programming |
| written description of system for users and tech staff | documentation |
| tasks and schedules for training, conversion, testing. anticipating and dealing with resistence | implementation planning |
| do this because IS usually not intuitively obvious | training |
| testing each program in system by itself | unit testing |
| testing system as a whole | system testing |
| full system, organization at once | direct cutover |
| start with a small part of organization | pilot cutover |
| one subsystem, then another | phased cutover |
| run old and new simultaneously | parallel (acceptance) testing |
| transfer of data from old files to new files in new formats | conversion |
| fixing errors | maintenance |
| adding new features | enhancements |
| two methodologies to analyze and design IS | Structured and object-oriented methodologies |
| techniques are step by step, will defined. | structured methodologies |
| focus on modeling processes or actions that manipulate data | structured methodologies |
| separate data from processes | structured methodologies |
| represents processes and flow of data between them | data flow diagram |
| breaking processes into successive layers of detail called high level and lower level views | decomposition |
| top down chart showing each level of design, each levels relationship to other levels, and place in overall design structure | structure chart |
| data encapsulated in object | object oriented methodologies |
