This section isn't staying like this. It is a staging area for the rest of the book.
Eventually a chapter called resources will contain blank templates for activities throughout the book.
The environment the project will be finally used in, will vary from very quiet when only a few people are viewing it, to very noisy when a school trip views the exhibit. The target project audience is most likely to be very noisy when in numbers. The overall temperature will be fairly constant due to the air conditioning required by the butterflies. Lighting will also be constant, as the project will be indoors, and can be easily controlled. In the habitat there will be a constant temperature of around 28 degrees Celsius with 90% humidity with the temperature only dropping slightly over night. There should be no obvious problems caused by the climate due to the fact that any hardware will be contained entirely inside or entirely outside the habitat.

Storyboarding was vital to our development. As we all hated documentation, we used storyboards as often as possible which saved a lot of time and misunderstanding as we could all see what others were thinking.
Interface storyboards had multiply stages where many details were changed and many potential problems were found. Most of the storyboarding was done in the first three months with almost post storyboards done on whiteboards in the main being small modification to the original storyboards
The following storyboard was used for presentation to show the client an overall design concept and to illustrate our current understanding of the interface requirements. The final product has two main changes from the following storyboard, there is no VR section instead there is a third person flyer section and the projection display has become the final section. Nether of these changes require any storyboarding to implement so no was ever made.
THE SYSTEM SHALL||DESCRIPTION
|FR 1||Allow the museum to have an interactive software activity based on butterflies.||The museum provides a learning experience for museum\’s visitors.|
|FR 2||Allow people to create their own virtual butterfly.||Features will be provided to allow people to design their own butterfly.|
|FR 3||Allow a butterfly entered into the database to be retrieved by its creator.||A database will keep butterflies so that people can come back and see them again.|
|FR 4||Limit the amount of time a user can use the system.||To keep the line moving so many people can use the system.|
|FR 5||Appeal to both adults and children.||The need to appeal to the greatest number of people is an import factor|
|FR 6||Butterflies shall fly and move around and interact with the environment.||To make the display interesting to watch and a better overall experience|
|FR 7||Butterflies will be deleted after a set amount of time.||To free up resources for more butterflies and to complete the life cycle. Database files will remain but de-activate because it is bad practice to delete any thing of a database.|
|FR 8||Show the natural life cycle.||The complete life cycle of a Butterfly showing the four major stages|
|FR 9||Cater for ages 8 and up.||Able to be used by most people above the age of 8 without aid.|
|FR10||Flexible enough to handle a different topic.||The overall design should be able to handle being changed to display another concept|
|FR11||Give users the opportunity to take something home that relates to the exhibit.||The museum wants their visitors to have something physical to take away to inform whilst advertising the museum and the tropical house so as to generate new and repeat visits.|
|FR12||Must have a shutdown procedure for when the power is turned off.||There are many powered displays in a museum. A shutdown sequence is more complex than a switch therefore its desirable.|
|FR13||Must have a start-up procedure for when power is turned on.||The same as shut down. Power on is as complex a task that should be ask of museum staff when start the display.|
|FR14||Have a type of screensaver.||Screensaver will be needed because the monitors will be running for long hours. Also there is a need for a "screen saver" loop to entice and inform users to the product.|
|C1||Should not appear as a computer to users.||Most people find computers can be intimidating, boring or common. All of which are not aspects that are likely to enthral users to interact with them.|
|C2||Run unattended and be maintenance free.||Due to the fact that there will be very little maintenance available for long periods of time, there is a great need for the system to run without the need of regular attendance.|
|C3||Be completely robust.||Able to withstand the wear and tear of a museum interactive exhibit.|
|C 5||Show version number etc on start-up.||A version number is needed so there is no confusion to what version of software/ hardware is currently operating. Important when servicing or upgrading software.|
|C6||Function normally within a humid and varying environment.||28˚C and a humidity of 90% are the conditions within the butterfly house. The system may also be installed for a time in the museum foyer other areas which may have varying conditions.|
|C7||Be able to handle up to 1000 users a day.||The number of visitor to the museum is very erratic due to the likes of holidays and weather. It is also common to have large group visits such as tour or school groups. This mean that the system may have times that it is constant use throughout a day or not at all.|
|C8||Offer different levels of information||Able to cater for those who want to know more.|
|C9||Offer the user a reason to return||Some reason that a user will repeatedly return to the exhibit.|
Locked in to an expensive software system Historical Data remotely stored and not easily accessible or adjustable Upcoming legislative requirement to have historical records of all booking and dispatch data
Booking Table The booking table is used to store information on specific bookings, which are later referred to on the job table if they successfully become jobs. There are 2 relationships to the Address table, one to reference a pickup address , the other to reference a destination address. There are also 2 relationships to the shift table one to record the operator who made the booking, and the other to record the dispatcher who assigned the job.

Project executive summary
The goal of this project is to provide a dispatch system for City Taxis. The Dispatch System should be ready for use as soon as possible.
We are using a methodology that combines iterative and Agile thinking. We believe that understanding grows throughout a project, therefore through the use of prototyping and regular meetings with stakeholders, constructive feedback will be created to ensure the implementation of a successful system. The system should facilitate dispatches and provide historical records.
Main risks identified so far include: lack of compliance to legislation, loss of privacy, inaccurate data, insecure data..
Project Name: Taxi Dispatch System
Team Name: innovate.It Team Members: Hamish Smith, Shane van Dyk

We strive for to be the best and nothing less.
With over 55 years of service to the people of Dunedin, we at City Taxis are committed to offering our customers the very best service and value for money.
Section Three: Methodology Project Methodology
The Agile methodology encourages realistic schedules and resource allocation, allows for changing requirements and technical complexity of projects. It also takes into account technical shortfalls of group members and access to appropriate technology. Phased life-cycle approach to help the group realize what activities are to be undertaken, what deliverables for each stage may be, enable different types of communication between activities and different stages, determine whether deliverables of each stage are satisfactory prior to proceeding to the next stage. The relative quickness of each cycle means that the team and client are revisiting the stages of the project a number of times, and therefore there is a higher probability of completing a project that satisfies the client. This also allows the flexibility to adjust to the changing client/ project needs. Regular use of “Scrum” meetings (15 minute regular meetings between team members, and client) facilitates a high standard of communication between team members and the client, and keeps the focus on what is happening next and who is doing what. The use of prototypes allows the client to kinesthetically experience the development of the project at regular intervals. This promotes constructive feedback from the client, and increases the probability of the project moving in a direction that meets the stakeholders requirements. Because construction and evaluation is happening throughout the project, there is a greater likelihood that the finished product will meet the stakeholders’ needs. Understanding is not expected to be obtained by all parties early in the project. It is expected that as all parties are involved in a constructing, evaluating process; understanding will continue to growSection
City Taxis needs an improved dispatch system that facilitates taxi dispatches easily and successfully, while accurately recording all data needed. The main hub of City Taxis consists of phone operators and a sole dispatcher. The phone operators deal with customer bookings. The dispatcher allocates the jobs and communicates with the drivers. The current system seems to facilitate the dispatch jobs quite well in the office environment, but at a high financial cost. The current communication system between the taxi drivers and the main office, seems to have time delays and distracts the drivers more than what is considered necessary. The ability to store data that is easily accessible is paramount, as future legislative requirements specify that certain data is accessible by police. The immediate desire of the client is that a system is put in place that accurately records the dispatch data for future reference, while providing an easy to use front-end interface.
Project risks Software development is intrinsically risky and uncertain which is why we need clear and measurable goals at the start of the project. The main project risks include the inability of software to perform to expectations of users and the inability of software developers to produce a working or functioning system for users. Also:
• Failure to gain user commitment • Lack of adequate user involvement • Misunderstanding user requirements • Failure to manage end user expectations • Conflict between different users • Inadequate user training • Running out of time
Green Card, Red Card Early on in the process we left a card system for City Taxis staff to use to comment on their current system. Things they like could be written on green cards, things for improvements on red cards.
Discussion 23 July
• A booking always requires a phone number and a name • Situations are going to occur where there is no street address. In this case, the pickup needs to have a location which is to be given a suburb and an area • In theory, it doesn’t matter if there are duplicate location entries in the address table • Shortcut do not dynamically updates, and would have their own interface for editing • Instructions is an optional field • Address numbers are not compulsory • Rules that apply to pickup also apply to destination • Vehicle type is an optional field and by default is blank • Time required is compulsory and defaults to current time • Number of passengers is optional • Large boot is to be removed from the form • True value for Bike Rack will generate “, Bike Rack” to be concatenated into the vehicle type field of the dispatch screen. This happens when dispatch data is generated • A booking requires both a pickup and a destination
Current State of Booking Form • Data does not get recorded properly if there is no street name • There are currently no booking validation processes, anything appears go in regardless of how little data there is, although no data is created if some pieces of data are missing • If a blank booking is made no data goes through, yet the dialog “Booking Saved” is displayed • A booking requires a pickup and a destination address otherwise no new data is recorded
TaxiDispatch Functional Release
13 August 2007
Before going to City Taxis I made a last minute change to the code on the booking form to make phone numbers optional. This suits their needs at the moment better.
On arrival I split the database putting the backend on a folder on the computer to be used as the dispatchers workstation, mapped as the “T: drive” on City Taxis’ local area network. I packaged up the frontend into an install file, and had the setup file created to a shared folder on our polytech computer. The program was installed on all machines on the City Taxis network and testing began.
Problems and suggestions arising from the test included: • Dispatch job screen not working correctly. Jobs will not clear if there is more than one on the screen. This is probably nothing more than a programming bug. • The are delays experienced after saving a booking or clearing the booking form of around three seconds. Most of the time this is OK but could be a problem during busy times. Even so at any time a three second delay is long enough to be annoying. • There is no ability to cancel a booking. • We haven’t facilitated for different vehicle types. No restrictions are imposed, meaning a booking can be made for 6 passengers in one car even though this is not physically possible. • The drop-down boxes to help with address details do not work with the down arrow key. • Special instructions do not appear to be going into the database. • Various corrections to the street database and additions to the list of location shortcuts were made, some still need to be made. • A suggestion was made for the next release that the dispatcher needs to be able to reposition a car on the board at any time.
I spent the first hour or so showing the booking form to the staff on duty and supervised their usage thereof. Afterwards I sat at the dispatchers desk watching dispatchers and generally made myself available to write down suggestions, comments, and problems. Some problems with data I was able to fix instantly on site using the polytech computer to access the backend and edit data on tables directly.
Order of Development
• Look at dispatch board and discuss wireframe interfaces • Design wireframe interfaces • Paper based prototype • Design options • Platform discussion • Create basic prototype • Make platform decisions • Task analysis • Detailed interfaces • Back-end development/migrating • Creation of logical procedure layer • Building/modifying booking front end • Building/modifying dispatch front end • Building/modifying historical and configuration front ends • Data dictionary • Technical documentation • Software manual • Help structure • Testing • Testing on site • Live robust release
Ruled Out • Physical Board: not practical, does not fit in with needs of client
Combination Options: 1. Access tables + Access queries + Access forms 2. SQL Server + Access queries + Access forms 3. SQL Server + Stored procedures (SQL server) + Windows application 4. SQL Server + ColdFusion + HTML 5. Access tables + ColdFusion or PHP + HTML 6. SQL Server + ColdFusion or PHP + Google Maps
Ruled Out • Option 6: Google maps does not match up with the requirements of the wireframe interface • Options 1 and 2: These options use Access forms which do not practically support the features of the wireframe interface • Options 4 and 5: These options use HTML as a front end. This does not have a proper coding environment, and would make for complicated and difficult attempt to support our wireframe interface
Leaving • Option 3: SQL Server + Stored procedures (SQL Server) + Windows application
The SQL server is the best suited backend because, unlike Access, it is designed for a multi user environment and has better stability and facilities for backups. It is also less restrictive in what we can do with the data.
Stored procedures on a SQL server would make a good logical layer because they are held close to the actually data, and once it is created it will make front end development much easier. There is bigger scope for customised procedures to fit in with the needs of the front end.
A standalone windows application is also the best platform with which to make a front end, because as we will be designing and building it ourselves, we can make it meet our requirements. Microsoft Visual Studio is probably the best environment to code with, as it will have facilities to connect with a SQL server data source.

The system shall allow for updates while still being used online 20. The system shall notify developers of any downtime eg message output “Screen B in Retailer XY, 111 George Street is not responding” 21. The system shall be portable using mobile platforms eg cellphone, PDA, MP3 player (therefore profile file size is important) 22. The system shall be able to build a profile online using a 56K connection 23. The system shall be able to send targeted text messages using Bluetooth technology 24. Users shall be able to search on past purchasers (eg bought within last 3 months, 6 months, 12 months, etc) 25. Users shall be able to append their wardrobe items to build upon their profile (may need to be capped eg 50 garments using low resolution images) 26. The system shall limit suggestions to top five rated out of all possible combinations according to the user profile 27. A user shall be able to continually build upon their profile by adding information eg making additions to the virtual wardrobe 28. Retailers shall be able to use the system to send purchase suggestions to targeted user profiles (eg women aged 30-35 who earn >$35,000pa and are pear-shaped with fair skin) 29. A user shall be able to search for wardrobe suggestions online via advanced searches eg particular style, retailer, price, etc 30. User shall be able to view generated fashion items, interchangeable with other suggested items 31. User shall be able to text suggested outfit to others requesting feedback (using 3G technology eg Rate this outfit for me please = 1,2,3,4,5) 32. The system shall be able to weed out bogus profiles (eg non-proportional biometrics provided by users to create unrealistic profiles)
The above diagram also shows the coathanger concept where coathangers are used to rate each item. The more green hangers an item has the more suitable that item is for the user, and the more red hangers an item has, the more unsuitable that item is for the user. Hangers can also be half green and half red as the hanger rating comes off a suitability index so an item can be 3.5 coathangers out of 5. We looked at using a colour slider bar for ranking items but decided to go with a star rating (using coathangers as that is unique) instead.
