Project Schedule (Planned vs Actual)

Between Acceptance and Midterm, everything has proceeded as planned, with some changes as mentioned in Project Highlights. Other changes have been logged in our change log. (Please see section on Change Management

We've had some delays with respect to our client as they were more busy the past months and did not have time to provide us with required information to proceed with some of our functions. We are currently 8 days behind in Sprint 6, and we will be trying to get back on track in Sprint 7 by putting in more work hours each day.

An overview of our project can be seen in our Project Schedule page. A detailed schedule is also available in the page.

Project Risks

Click to view our expected risks.

Here are some updates to our expected risk, some of which appeared in our project and we have effectively mitigated the risk by pre-empting it.

Risk Probability Impact Mitigation
System cannot be deployed to client’s server on time and user testing will be delayed.

Unable to do integration with existing systems in client’s server.
High High Replicate testing environment on our own server for initial user testing.

We have activated this mitigation step. We will no longer be deploying our system on the client's server. Instead, we will host the system on the IS480 server.
Change of requirements Medium (Now high) Medium (Now high) Review the requirements list with client at every iteration so changes can be addressed as soon as possible. We have also a change log to record the changes. More details can be found in our Change Management section.
Bureaucratic process for getting through compliance. High High Find out the documents needed for compliance and prepare them beforehand so less time is needed between stages of compliance.

We are no longer deploying our system on our client's server due to the long time needed for the IT department to process the request. We will not be implementing the functions of authenticating with Active Directory and Single Sign-On, instead we will replace it with an Admin Panel.More details can be found in our Change Management section.
Development team is unfamiliar with the development environment (.NET, Active Directory). High High (now the impact is medium) Though we have taken more programming hours than expected for features (due to being unfamiliar with the programming language), we only face minor delays in our schedule, some of which are unavoidable. Please refer to our Metrics Management page for more details.


Tehnical Complexity

1. Customizable fields and phases

Our system allows for the PAF template to be modified in the long run. This editable feature allows user to dynamically add, remove, or reorder the fields in the PAF template. Any changes made would then be reflected as the latest PAF version and used when new projects are being created. Old projects will still retain the template that was at the point of creation.

Editable PAF Template
Our Editable PAF Template can handle any number of field inputs and keep tracks of the sequence, making use of Model Binding, Model Validation, HTML Helpers, Partial Views and JQuery.

By implementing the DefaultModelBinder in ASP.NET MVC, our system can bind submitted form values to arguments of action method in controller and at the same time capturing the sequence of field inputs. It works perfectly for collection if we are posting a collection of primitive type.

Dpenz Model Issue.png

Unfortunately, that is not a very robust approach when the collection consists of complex type. Issue arises when our system can’t distinguish from the fact that there may well be another field input unrelated to our list of model atributes which could throw off our binding.

Fix To Resolve The Issue
Dpenz Model Fix.png

Since we can’t distinguish that there may well be another Name input unrelated to our list of Phase which could throw off our binding. Our system provides an index (GUID) for each item and uses TagBuilder class to build HTML.Helper which in return is used to bind the complex objects to the model, it also retains the order of items within the collection when it is being passed over to controller as an object. This ensures we can unambiguously match up the submitted properties with the correct object.

JQuery
JQuery is being used heavily to allow user to dynamically add and remove Models, drag and drop the field inputs within the PAF template. However, cache must be cleared all the time to resolve the duplicating ID issues created by the GUID fix mentioned above.

Render Partial View
Dpenz Render Partial.png

The PAF Template is then broken down into 3 component and implemented with HTML.RenderPartial to manage it individually. The overall template maintains a partial view while Phase and Phase Fields input Model are each being rendered partially. This provide advance form management when our system to break down a Parent Model consisting of several child Models, and each child model is rendering its own view for display and capturing any modification made to that model itself.

2. Restructuring Database

Previously, the database stores the form fields as columns and the data pertaining to respective project as row, as shown:

Project_ID Field_Name_1 Field_Name_2 Field_Name_3 Field_Name_4 Field_Name_5 Field_Name_6 Field_Name_7
1 Data 1 Data 2 Data 3 ? ? ? ?
2 Data 1 Data 2 Data 3 Data 4 Data 5 ? ?
3 Data 1 Data 2 Data 3 Data 4 Data 5 Data 6 Data 7

This does not ensure data consistency by allowing for additional fields to be added in the long run without modifying the table structure. Catering to any number of fields means table columns would increase as time goes by. Data inconsistency occur when user modify the name of an existing field to another when previous projects have data associating to that field. This also makes it hard for our application to keep track of relevant details for searching, editing, approving and auditing.

As a result, we have restructured the database tables to accommodate for the changes made in PAF template.

Dpenz Revised DB.png

Template Table -Stores the fields information pertaining to template.
Project -Stores field values pertaining to basic fields. E.g. Project Name, Project ID, Functional Owner, Project Budget.
Project Extra -Stores field values of phase fields and refers to Template table to determine its field type.


3. Popup Modal

Dpenz Modal Supplier.png

Our system made use of popup via server as compared to the typical client end in script. A typical process of short-listing suppliers while updating a project details would require the procurement staff to browse through the list of suppliers available and make comparisons.

When the procurement staff founds out that their desired supplier is missing, they would have to perform a search or create a new supplier into the system. Usually, users would open a new tabs to perform these actions. With the Modal, our system opens up additional window dialog which allows user to perform Supplier Management functions such as creating, searching or even selecting of suppliers to aid in their project editing process.

However, when implementing the Popup Modal, the newly created supplier or selected supplier information is not passed back to the parent.
Fix for Modal

Quality of Product

We designed our system with usability as our priority. As such, we allow for customisability such as customizing the PAF template and some report generation fields. To make the Edit PAF Template easier to use, we also implemented the drag and drop functionality. On all tables, we have also implemented the sortable function so users can find their desired data easily. We also have several search bars to make locating information easier.

Most importantly, our system is maintainable with minimal hardcoding.

Testing

We have completed a total of 4 user testings, including a heuristic evaluation. Details can be found on our User Testing page.

We also perform regression testing on our functions every iteration. Details of the bug trackers and metrics can be found in our Metrics Management page.

Reflection

Team Reflection

We have learnt how to work with a new language and framework: ASP.NET MVC4. We have shared our resources on the Knowledge Base page here.
In our project, we have also learnt how to be adaptable and handle constant change requests, as well as how to react when we are faced with delays in communication.
