Lesson 8 Study Journal

We can use prototype in different areas, such as reveal technical issues, display work flow and task design.

Using a prototyping in illustration of business process is a method to verify whether a system working well. This method is visual, which is suitable for people to discuss.
The other advantage of prototyping is that it shows the interface of every component, so that designer understands the interaction from each part simply.

Why use prototyping
  • Easy for evaluation and getting feedback

  • Presentation to investor

  • An aid for members to communicate

  • Test of new ideas

Lesson 7 Study Journal

This lesson is about management of change. Change is constant. In EDCF, change describes in Change/Agency, while Universal Business Model categories change in Influences and Performance mostly. Risk and opportunity come from change.

Change comes from:

Great Idea: It is a new model, new process, and new method to handle business
Improvement: It is a modification of existing infrastructure, business process, software, and interface etc.
Sudden Event: Such as 9/11, Asia Tsunami, financial market crash
New Technology: Internet, mobile commerce, eyes/finger print check and GPS etc.

Small Business Disaster Recovery Strategy
Small business will spend less money on DR compared to large company; meanwhile small business has less data to protect.

Two main solutions to DR are Tape back up system and Host-based replication system.
Host system is able to physically distribute the data in different place, but more expensive than Tape. These two solutions can be used together. (Mike Talon, 2004)

If the data is kept on back up, the space in disk will become less and less, it is impossible to store all the data. So a clarification and deletion is necessary in back up management.

Lesson 6 Study Journal

This lesson is about designing interface between different parts of the business system. Again, we should consider the existing interface first, what we do is modifying or creating a small part of the interrelation. After that we should be able to evaluate the whole EDCF system.

Opera Analysis
Performance of Opera is providing a platform for act. The light, sound effect decorate is the internal infrastructure, and the traffic system, ticket selling network and human management could be external infrastructure. How to manage of renting of Opera, deal with proposal and get benefit is the business model. There are lots of famous stages in China, how to attract actor and audience is the main issue of agencies.

There should be several systems in Opera, such as proposal evaluation system, infrastructure management system, advertising system and market research system etc.
In order to evaluate a project, data should be collected in different system, to decide whether invent on a proposal. When the ticket starts to sell, infrastructure system calls for advertising system to do promotion. Advertising system replies on market research system data, niche market and target the audience. The market research system should acquire the data from infrastructure system to reevaluate and rearrange the performance process.
