A couple of weeks back, someone asked me what I did so. What do I do? Why am I starting a company called Open Source Strategies? Later, I understood why I used to be baffled: Unlike most of my peers, I’m not wagering on a particular technology. Can we make software better with open up source procedures? Can we develop better software? Would cooperation allow us to get better ideas?

Is remote, asynchronous development more efficient? Can a collaborative environment attract better programmers? In other words, are there smart people working outside your business? Can peer review help us write top quality software, with more flexibility and fewer defects? Can we build better software businesses? Reduce the cost of developing software by using existing open source code?

Avoid wasteful R&D assets with a tighter vendor-user romantic relationship? Lower distribution costs achieved through an open source model? Move to a demand-driven business model? I do not believe we can replace the commercial software business model with an open up source one. Rather, I question if we may bring the best of both worlds–the invention together, creativity, and efficiency of the open source model and the resources and business of the commercial one.

A use-case diagram can be used to graphically depict a subset of the model to simplify marketing communications. There will typically be several use-case diagrams associated with confirmed model, each showing a subset of the model elements relevant for a specific purpose. The same model element might be shown on several use-case diagrams, but each instance must be consistent.

If tools are accustomed to keep up with the use-case model, this persistence constraint is automated so that any changes to the model element (changing the name for example) will be automatically shown on every use-case diagram that shows that element. The use-case model may contain packages that are accustomed to structure the model to simplify evaluation, communications, navigation, development, maintenance and planning.

Much of the use-case model is actually textual, with the text captured in the use-case specifications that are associated with each use-case model component. These specifications describe the movement of events of the utilization case. The use-case model serves as a unifying thread throughout system development. It’ll typically be followed by an RFQ or RFP.

RFI is broad, and does not necessarily require financial discussions to take place. know how you want to solve it ’t. This is the most formal of the “Request for” processes and has strict procurement rules for content, vendor and timeline responses. The appendices in the Guide to Successful Software Acquisition provide templates because of this approach.

RFP is just as much about price, as all other aspects. RFP requires more effort for both you and the prospective contractor. RFP slides easily into contract negotiation and task outlining. It is used showing how data is moved between different processes. DFS’s are in problem site rather than in solution website. They are basicly top level style of how something functions based on flow of information. Also there is absolutely no support for concurrency representation in DFD.

Activity diagram is actually a flow chart to signify the movement form one activity to some other activity. The activity can be described as an operation of the system. The basic purposes of activity diagrams are similar to other four diagrams. It captures the powerful behaviour of the system. Other four diagrams are accustomed to show the message flow in one object to another but activity diagram can be used to show message flow in one activity to another.
