1. Prestwood MVVM Shell

A rigid and clean ASP.Net MVC implementation based on MVVM appropriate for our Formal/Robust paths. The PM wil ensure the same coding techniques are used for all coding using our MVVM architectue.

Techniques which are limited in our MVVM architecture and include use of Telerik controls (licensed separately), direct access to the database (coders must go through an implemented data layer), use of GUIDS, lighter use of database views, and stored procedures.

C# Web Application using ASP.Net MVC to MS SQL.

This task includes:

  1. Setup basic shell database (user tables added in a separate task).
  2. Menu system with Admin menu added (user menu options added in a separate task).
  3. Login screen.
  4. Admin menu user management option with supporting form with defined users: Admin, and User.

2. 1 of 2, AppName 1.0

Step 1 of 2: Discovery

  • PSDP Feasibility Phase: Setup legacy system for coders. Document legacy system using automated tools.
  • PSDP Requirements Phase: Identify forms and reports to convert. Document terms, actors, and identify use cases. Identify enhancements (if any). Identify tables in use.
  • PSDP Design Phase: Build new database. Initial screen design mockup. Document business rules and additional documentation of use cases.

Step 1 deliverables usually include a project plan for the Step 2 of 2 build-it phase which serves as the requirements, a new database, and a GUI mockup. Each form and report becomes a task in step 2 of our 2-step process along with other known tasks such as build data migration program, build MVC Shell Application, user subsystem, and admin forms for maintaining users, lookup tables, etc.

Step 1 of our 2 step approach is used to start a project with discovery. Step 2 is build. The goal of discovery is to document known requirements, some initial design, and a project plan. Step 1 of our 2 step includes at least the following tasks: Gather Requirements, Build GUI Mockup, and Create the Initial Database. The Requirements task becomes the project plan for step 2, Build.

Discovery can include additional tasks such as documenting an existing application, data cleanup, and even a task or two from the initial coding phase such as implementing our Prestwood ASP.Net MVC shell which includes some initial design, and member management.

If this ticket is not authorized, the printed version of the Project Plan is the Project Proposal for Discovery. Once authorized, the tasks of this project are completed. The requirements task is completed by creating a Step 2 of 2 project ticket which becomes the project plan and/or the proposal for Step 2, Build.

3. 2 of 2, AppName 1.0

Step 2 of 2: Build-It

  • PSDP Initial Coding Phase: Build MVC shell with user management and login. Build data migration program. Build initial forms. Alpha builds. Add mobile readiness.
  • PSDP Testing & Rework Phase: Beta builds with optional double entry alongside existing application.
  • PSDP Deployment and Maintenance Phase: Deploy. Establish maintenance plan.

Step 2 of our 2 step is used to complete an application by building it. This step 2 project ticket is created during discovery, during step 1 of our 2-step process. For projects over 500 hours, we break up our step 2 of 2 into multiple projects of 500 hours or less. In which case, the App Tickets option on the application menu tracks overall progress.

This project ticket documents requirements in App Artifacts. However, there may be some completed requirements in previous projects including step 1 projects, which is appropriate. This project also documents any tasks that are required to complete the project including PM, testing, and deployment. The combination of tasks and artifacts in this project represent the project plan for building the app.

If the client has authorized work, it is set to In-Progress and work can start as soon as resources are ready which means, depending on billing relationship and approach, this step 2 build project can overlap with a step 1 discovery project. If this ticket is not authorized, the printed version of the Project Plan is the Project Proposal for Building of the next version of the application.

8. Convert, Identify Forms/Reports

Identify scope of the user interface. First, we identify forms and reports in use. Then narrow that list to what will be converted. In every case, the client drives this process with our help. Any forms or reports missed, can be added to the project when discovered. However, the client is responsible for validating the scope of the project. Each form and report is added to the step 2 of 2 build-it phase either as a task by itself or as part of task.

9. Deliverable: GUI Mockup

Develop a GUI mockup that is not connected to a database. Although it can evolve, your goal is to specify the specific look and feel of the final application.

Rules:

  • Should have look and feel of final application.
  • Okay to build the technical shell and have a web developer skin and theme it.
  • Cannot be connected any data.
  • Should contain all major forms.
  • Long forms can have some fields skipped but you should include text on the form indicating such.
  • Simple one table lookup forms can be skipped but the menu option should be included.
  • Do NOT include reports as those will be specified later. Although, menu options with reports is okay.

10. Deliverable: Initial Database

Create initial database. From an OOA viewpoint, you are identifying entities and attributes which is usually a requirements phase task. For us, we create an initial database that frequently evolves into the final database. With the initial database, your focus in on creating tables and fields and this task can be part of the requirements phase.

If converting from an old app, move existing tables and views only. If using an Informal Path, then normalize the database a reasonable amount ONLY. If you want to normalize more than very little, seek authorization from the client, but make sure they understand this will add to the cost of the project. If taking a Formal or Robust path, normalizing database more than a very little is still optional.

11. Deliverable: Requirements Document

To Do:

  1. Create a new project ticket to store requirements.
  2. Create 1 tasks or artifact for each specific feature or deliverable to the client. For example, one artifact for the framework, and one for each form, report, and supporting application such as an installation program, or help file. If a printed user manuel is desired, we usually complete that with a separate Documentation project, but you could add that as a task to the requirements document as well.

2-Step or Rolling Estimates

With our 2-Step approach, we stop after an initial step-1 effort and seek authorization to build the application. With our rolling estimates approach, we just roll right into building the application frequently starting the initial coding phase toward the end of a Req+Design phase.

Informal, Formal, and Robust

For our PSDP informal path, the requirements project is approved and we usually just roll with the requirements project as Step-2 of our 2-Step approach. With our Formal and Robust paths, our preferred technique is to copy the initial requirements into a new project and close the Initial Requirements project as complete prior to building the application. This allows us to establish a baseline of requirements and estimates we can measure ourselves against as the project proceeds. Plus, it clearly documents and changes in scope.

12. Document Known Terms

Every business and custom application uses terms defined for their business. Definitions help clarify communication by establishing the meaning of verbiage and can be either a word or phrase.

To do: Ask client for a list of terms. If they do not have a list, perhaps client staff can generate a list of definitions to kick-start documenting of known terms. We will add to the list as we discover them.

Deliverable: Included as part of the App Specification from the app menu, or printed and/or delivered to the client for review anytime from the App Definitions page.

14. Generate Legacy Paradox PDFs

Create documentation directly from legacy Paradox system. We have a suite of PDoxDos and PDoxWin analysis tools which create our data models, data dictionaries, file inventories, and searchable reference databases. This documentation is used to create the new database as well as to extract many data driven business rules. This step includes setting up the legacy system with data in our development environment so developers can exercise the legacy system anytime needed throughout both steps of our 2-step process.

Deliverable: Saved as PDFs on drive P as well as sent to the client in an email.

15. Identify and Document Actors

An actor represents a role or user of the application. Actors are defined with each application and can be linked with one or more requirement items, forms, and/or use cases (business processes).

Deliverable: Included as part of the App Specification from the app menu, or printed and/or delivered to the client for review anytime from the App Actors page.

16. Identify Use Cases Only

After forms are identified, we initially identify but do not document in detail use cases (business processes). The documenting of uses cases can occur later in step 1 or early in step 2 of our 2-Step. Each use case is identified, labeled, and assigned to 1 or more actors as part of the Task Artifact that is identified with the specific form that contains use case, or in a UML Use Case diagram to accompany our standard documentation. If only a UML Use Case diagram is created at this point of the project, then the UML Use Case diagram is used during the Document Use Cases task where each use case and actor are associated with a specific App Artifact and documented.

Deliverable: 1+ tasks in step 1 or 2 of our 2-step. Optionally, we can deliver a UML use case diagram.

17. Initial Pre-2-Step Discovery

Sometimes clients want to start a project with a small task or 2. This pre-project work is considered part of discovery and may include feasibility, documenting of an old system, data cleanup, etc. As soon as appropriate, the formal discovery should start with our Step 1 of our 2 step process.

21. Paradox on Terminal Server

Paradox Exit Error 1:
Save Configuration File
the file 'C:\Program Files\...\config\PDX_EN_FULL_sbar.cfg' could not be opened. Paradox Exit

Error 2:
Save Configuration File
The Statusbar Configuration File could not be opened.
The configuration cannot be saved.

Paradox Exit Error 3:
The file 'C:\Program Files\...\config\PDX_EN_FULL_bars.cfg' could not be opened.
The configuration cannot be saved.

BDE Error:
Database Engine Error
Cannot find Engine configuration file.
BDE Error: 8452 [$21][$ 4]

The Solution

As with getting most legacy applications to work correctly on Terminal Server, getting the BDE to work is a matter of rights. Once rights are setup, you can then configure the BDE.

There are many ways to solve these specific rights errors. One easy solution if you trust the users using the terminal server is to add them as administrators to the terminal server. An elegant way to accomplish this if you're using Active Directory is to add your user group to the Administrators group of the terminal server.

22. Prestwood MVC Shell

A flexible, get it done, ASP.Net MVC implementation based on standard traditional techniques. Appropriate for our Informal/Formal paths. The PM will NOT ensure the same coding techniques are used for all coding in favor of a satisfy the requirements approach. Syntax consistency is ensured by the development tool. Consistency of coding techniques is encouraged with good communication among the coders. Good solid coding techniques are used in all cases. Acceptable techniques which are limited in our MVVM architecture include direct access to the database bypassing an implemented data layer, use of autoinc keys over GUIDS, heavier use of database views, and stored procedures.

C# Web Application using ASP.Net MVC to MS SQL.

Includes:

  1. Setup basic shell database (user tables added in a separate task).
  2. Menu system with Admin menu added (user menu options added in a separate task).
  3. Login screen.
  4. Admin menu user management option with supporting form with defined users: Admin, and User.

24. Prospect, Build App, Convert from Old

Feasibility Phase, which is part of Discovery, can include documenting existing system, establishing scope of new application (meaning document what is in old app that is not needed, plus minimal needed additional features).

Time Estimate: Although it depends on the complexity of the old application, feasibility usually ranges from 16 to 40 hours, but for larger complex applications, they can be several hundred hours.

Goals:

  1. Define new project as a Strict Technical Conversion with few additions, or define as a Technical Conversion with Additions.
  2. If appropriate to do a longer Feasibility Phase, then initiate a Feasibility Phase project.
  3. If client is ready to proceed, define 2-Step approach, initiate Step 1: Requirements (What) with minimum deliverables of Requirements Document, Initial Database, and GUI Mockup.

Note: For the best chance of a successful project, limit changes to as few as reasonable.

25. Prospect, Build App, New

Feasibility Phase, which is part of Discovery, can include converting any existing documentation into our system, or we can just get started by kicking off a Requirements+Design project.

Time Estimate: Although it depends on many factors, feasibility usually ranges from 0 to 16 hours, but each client varies. Our recommendation is that we kick-off a Requirements+Design project ASAP.

Goals:

  1. Define any initial feasibility tasks the client wants done plus propose any that come to mind.
  2. If appropriate to do a longer Feasibility Phase, then initiate a Feasibility Phase project.
  3. If client is ready to proceed, define 2-Step approach, initiate Step 1: Requirements+Design (What+Why) with minimum tasks of Requirements Document, Initial Database, and GUI Mockup.

Note: For the best chance of a successful project, limit version 1.0 to as few features as reasonable.

29. Setup Legacy App for Developers

When converting an application, developers need access to a working version of the old app.

Setup old application so Prestwood developers have access to exercising the application. The old app can be setup at Prestwood, or at the client. If at the client, we need VPN access available to the application throughout the duration of the project.
