Problems and notes

• We put last 2 weeks to reserve when we started the project and used them to finish the development phase

• We did not consider time to learn

• We also made a wrong evaluation of working hours excluding conference and study time (So actual cost is greater than planned)

• A man leaved the group sooner

• Next time we can improve the plan considering all these problems

SCORE Communication with customersWe contact and receive feedback from people located in different places (Europe, Asia, America)

• 40 people answered questionnaire• 25 personal interviews• 100 new ideas through e-mail• Advices gathered from over 10 large cities and over 6 countries

We asked for feedback to some disabled person, since we want to provide services to them

08-12-18

SCORE Additional Requirements

In addition to the SCORE proposal documents which contains only the limited and main requirements to make the advice system, we received some opinions and suggestion from potential users.

• Enhances usability with searching options, Easy way to select an Area• On mobile, route tracking system, videos• Cycle paths, petrol pump, youth centers, parking places• Shortest path or fastest path can make it better• Car and bicycle path are almost the same

Some sounds for blind people can be saved and retrieved as an advice.

08-12-18

SCORE Difficulties in Report writing

Main concern as Requirement Engineering.We read 5 different articles, books and paper to understand what actually Requirement Engineering is

• No native English speaker in group!!!• Making a rough draft and what to put in it and what is not required• Different writers, thinking, writing and structure style difference, rephrasing• Duplicate and repeated sentences ,trimming them down, long sentences• Feedback and comments from two supervisors sometime confusing• Impelmentation and report at the same time, concentration

Fill that Report is actually another English skills course or project in itself. End up with two projects in fact.
