Resource Kanban

by Xavier Comments: 0

There is no doubt that Kanban is great for software projects. With Kanban you can increase throughput by limiting work in progress, delivering value constantly this increasing trust in the team.

But Kanban does not only apply to projects. Some people use also Portfolio Kanban to manage projects.

And there is another potential use for Kanban that I think can be very useful and solve multiple problems if applied properly, i.e. in a services company: Resource Kanban.

Let’s start by outlining the problem:

  • In most companies, but especially sevices oriented companies, resourcing is always an issue. Projects usually start when customers want to or when legal decides they should
  • Also current projects might end up unexpectedly, ahead of time (yeah right!) or contracts are extended, sometimes longer terms but also little by little
  • Predicting when each project ends and others begin in such a way that resources can be allocated then becomes a really tricky proposition. On one hand if you don’t have a resource available to start another project then you might upset a customer and potentially lose little (or lots of) money. On the other hand, if there is a lot of time between one project’s end and another’s start then your developer is idle and you also lose money! Tricky indeed
  • So being able to visualize and maximize utilization as much as possible, without burning out developers, is critical

And thus it came to my mind that Kanban can be used to help this process. It is not a solution per se, but it is a method that allows to help schedule resources and understand potential idle and over utilized times.

And so I will explain what in my mind Resource Kanban can do for you. Stay tuned for a step by step explanation.


Disclaimer: a quick search on “Resource Kanban” indicates to me that no one has yet presented this solution to the problem in the way that I envision it. Please let me know if you already did so.

Bad Search Can Break a Good App – Real World Example

by Xavier Comments: 0

In my Pluralsight training, Getting Started with Enterprise Search using Apache Solr, one of the things that I make quite a bit of emphasis is on how important search is, yet it is one of the most misunderstood functions of IT and development in general. In this post I will show you an example of how a potentially good app is a pretty bad app mainly because of its search capabilities.

It is so much the case that in Twitter Pluralsight selected this phrase to tweet about the release of my course as you can see here:


But now let’s get to the sample. Here’s the scenario:

Problem: Life is busy. No time to go to the supermarket

Solution: use your grocery store’s web site to purchase your food and it gets delivered home the next day. Charming idea, did not work with Webvan, but it seems to be doing quite well for Amazon and in my home town one of the major supermarkets is doing it in a more controlled way with a good delivery service, all for $10. Not too scalable, but for a MVP it is ok. (Read Lean Startup if you don’t know what MVP is)

It may work or maybe not mainly because of a really bad user experience, but let me get to the point. UX is important! Never forget it!

You get to the app in and they have mainly 4 sections as you can see here


And here is what they are for:
– On the left they have a directory style organized by aisle. Grouping kind of works in my opinion if you are not too sure of what you want, but it is terribly slow and inefficient. They lose cookie points for this.


– Then in the middle they have a section where they display the products. This is very standard so it kind of goes through, however they lose cookie points again for having products without pictures or with very weird stretching. They are a supermarket, and a big one, so I am sure they can send a guy with an iPhone to take a quick picture.


– The cart has a problem which is that they do not actually display the product name, only the description. Who thought of this? Not even something as simple as a tooltip!


And then here is the deal breaker for me: BAD SEARCH! As mentioned in the post, search is one of the most misunderstood functionalities in IT. A lot of people make huge mistakes because search can be done with a database, which it can, but the end results sucks! And it did suck here.

Let me show you this. I want to look for “jabon dial” which means “Dial Soap”. So I just type “Jabon Dial”. Should work, right? It doesn’t! Look at the message: “No results found…”. Also I hate the CAPS. There may be 1 technical reason I can think of but it is pretty dumb.


But why? If you look closely there are 27 types of “Jabon Dial”, type only Dial


The problem lies here:
– The person that implemented this application had no knowledge of how search works, which is normal as search is pretty misunderstood.
– But humans don’t do search like engineers want. Having the user do a search exactly like the engineer wants is just lazy and ineffective.
– So engineers who created this probably went for a simple exact match in a database search
– This is a terrible user experience. I can bet the farm that Amazon would have closed its doors in the 1990s if they had such a bad search

How to fix it? Well, go learn how to use a search engine. And that’s why I created my course, Getting Started With Enterprise Search Using Apache Solr:

Getting Started with Enterprise Search Using Apache Solr

by Xavier Comments: 0

Enterprise search used to be not for the faint of heart or with a thin wallet. However, since the introduction of Apache Solr the name of the game has changed. Solr brings high quality enterprise search to the masses. Don’t leave home without it!

And let me help you get started! My intention is to create a series of posts where I can help you get started with Solr. This process can be easy if tackled with the appropriate resources, but it can be daunting if you chose the wrong ones.

I will start by describing what each module of my training covers, click on the bullet to be taken directly to the post.

  • Why Solr & Enterprise Search?
  • Architecture of an Enterprise Search Application
  • Solr Configuration
  • Content: Schemas, Documents and Indexing
  • Searching & Relevance
  • Making it all Work: Put a UI on It!
  • Final Words

My course is available in Pluralsight: Getting Started with Enterprise Search using Apache Sol. You can watch it here:

Dumb UX mistakes in IIS

by Xavier Comments: 0

This is just a quick rant/question. Does anyone know why you have to type your password twice when setting up the Application Pool Identity in IIS?

It seems an extremely dumb feature as #1 you can copy paste the password or #2 just type it but given you usually include service accounts here with stupidly complicated passwords then why do you have to suffer typing it twice?

Windows “evolves” but the underlying things are exactly the same. Can’t Microsoft spare a little bit of time making Windows more usable and fix little itty bitty things like this one that overall will have a better user experience?

Oh well, who cares about devs anyway!


Determine number of active connections to each database in SQL Server

by Xavier Comments: 0

So I am taking databases offline and I need to find out which ones have active connections to them. People usually do a


However that brings a lot of info that I don’t need. I prefer to use this query so I see the DBs with number of connections!

DB_NAME(dbid) as DBName,
COUNT(dbid) as NumberOfConnections,
loginame as LoginName
dbid > 0
dbid, loginame

Brilliant query!

Change owner of a Microsoft SQL Server database

by Xavier Comments: 0

We had a spaghetti of database owners so I decided to get this straightened out. How to do it? Simple!

– Open New Query in SQL Server Management Studio in the database that you want to change the owner
– Run EXEC sp_changedbowner ‘domain\owner’
– Wait for Command(s) completed successfully.

As simple as that!
