An infrastructure (Soo Locks, source:

The customer already provided a complete high level project specification, so I will begin defining lower level requirements. First I will define an infrastructure for the project. This is a desktop application, which means defining infrastructure for it is usually simpler than it would be for a server application. We will use:

We divided this project into several iterations. In the first one we will use just two developers, so I will use just a few agile techniques (no product / sprint backlog and agile metrics for now).

I have found that many developers dislike the idea of using a heavyweight integrated development environment and prefer lightweight editors like notepad++, vi or emacs. But after many years as developer, I have found that a fully featured IDE saves a lot of time with features like code autocompletion, refactoring or the ability to show errors without having to compile the application.

Coding conventions are used to standardize the code structure and for improving code quality. Many developers prefer to do the coding “their own way”, but sometimes that is not an option when working in a team.

Basecamp will be useful for discussing high level features and milestones, as it provides a lot of collaborative tools customized to distributed software development: white boards, forums, project schedulers and trackers…

Low level development tasks will be managed via Trac, as it integrates pretty well a version control software (which allows to share the source code and see what each developer changed), a bug tracking system (where the issues and low level task are managed) and a wiki (what is useful for writing both internal and external documentation collaboratively). In the next articles I will explain more in detail how these work, and how I will use them in this project.

We will also use vWorker for selecting developers, and we will initially pay for deliverables, so we have a fixed cost. If the developers does a good work in the initial part we will consider using pay for time, as it give us more flexibility and it’s better suited for agile development.


Agile management project: Python / wxPython based realistic test data generator for databases (I)

Note: this post was previewed and approved by the customer.

I was recently hired as a manager via vWorker (adquired by Freelancer on November 2012) for improving a realistic test data generator for databases written in Python / wxPython. We already have a working prototype, and we are going to convert it into a commercial application.

After asking permission from the customer, I will describe here the steps and techniques that I will use to manage this project. I’m new to Python and wxPython, but the existing code is clear, so I don’t have any substantial trouble following it.

So, if you are curious about how a project is managed in vWorker using agile techniques, and you want to follow a real case, don’t forget to use one of the subscribe links in the right menu. Feel free to ask any questions or post a comment.

vWorker invites me to the new Tech Sherpa program

…and this is really great as they just invited 4 people for this new feature. So, what is a Tech Sherpa? From the vWorker latest news blog:

A Tech Sherpa™ is a cross-discipline expert with years of success both “climbing” (doing technical work) as well as “guiding” (managing others who do that work). A Tech Sherpa™ can take over some or all aspects of managing your project, and free you to focus on more productive things. Prices range from $25-$95/hour, depending on their skills and location in the world.

So if you want somebody to manage your project, including writing specs, hiring people, managing them, and testing the work, now vWorker offers you everything of these plus a employer triple-point money-back guarantee and a workforce of more than 300.000 skilled people. You can create an account (completely free) here. And if you want to create a project just for me, just click here.

You can learn more about what a Tech Sherpa is and the new project management feature in the vWorker site.
