Agile driven requirements wishlist for Integrated Telcom Service Provider Packages

I am constantly frustrated by having to remember voice, data and SMS bundles not only for my own use but for my family and dependants, and I am envious of family data plans in the rest of the world.

Being an agile practioner here is my user story

As a telecom service customer I would like to purchase and track a single package for the users in my household and dependants

Acceptance Criteria

  1. The package includes the following services at a minimum
    • On-net voice calls
    • Off-net voice calls (same country)
    • SMS messages
    • Internet access
  2. All phone numbers on the package use the services transparently
  3. The package is paid for monthly, with the ability to purchase additional optional services as need
  4. Ability to add and/or remove numbers at will
  5. Ability to pay for additional batches of numbers e.g., 5 numbers – the service fee helps the telecom cover losses due to the service discounts
  6. Weekly and monthly payment options – to help manage cash flows
  7. Generation of tax invoices for the service payments
  8. Web/app based monitoring of service usage broken down to a daily usage
  9. Ability to set usage thresholds for all user at least 2 levels – I know individual thresholds may be difficult so nice to have
  10. Reminders to pay for services before they expire

What do you have on your wishlist for your telecom provider?

Crowdsourcing Validation Rules for Uganda National ID

I am curious about the ability to validate that the Uganda National Identification Number (NIN) is well formed. However this does not validate that the NIN actually belongs to the person presenting it or that it is correct.

The rules that I have been able to gleam are:

  1. Must be 14 characters long
  2. First character is a letter of the alphabet. C seems to be a common letter – does it stand for citizen?
  3. Second letter is either M or F – male or female
  4. Characters 3 and 4 are numbers, which are the year of birth. Cannot be after 00 since that would make a person below 18
  5. Characters 5, 6, 7 are numbers

How can you help? Which of these rules do not match your NIN? Share any additional patters to build a repository of rules that can later be mapped to programming language validations – Regular expressions and validation frameworks

TechTip: Installing Airtel Uganda Huawei E3131 on MacOS Sierra

If you are like me, there comes a time when you need to whip out old tech tools to solve a need. In my case it was Internet access in Hoima, which has MTN and Airtel as useable networks.

I have an old modem, which intially had a data simcard gone bad (that is a story for another day) however it was discontinued in 2012, so there were no drivers for Mac. The installation package terminates with errors so I was stumped.

Step 1 was finding the model which involved opening up the modem as below

Step 2 was to find an installation package, which after about an hour of Googling and reading involved using an Huawei Mobile Partner (https://www.dropbox.com/s/v33lsoe7qok0zsl/MobilePartner-MAC-V200R003B015D16SP00C983.zip?dl=0)

Once installed you can now use your modem readily. Hope this saves someone else some pain…

Styx Technology Group Launches Poultry Farm Revenue Calculator App

As part of the Styx Technology Group mission to leverage technology to support executives identify, implement & refine strategic technology interventions in their business & target market segments, we are proud to partner with Kkungu Poultry Farm Enterprises Ltd to help bring relevant, useable cutting edge technology to Uganda agriculture executives.

Leveraging the experiences shared in this post Poultry Feed Economic 101 – Changing the Supplier Scenario, the team has built a simple easy to use calculator to address this question using minimal inputs to help poultry farm managers:

  1. Estimate their spot profitability based on the cost of inputs and revenue from sales of eggs
  2. Use simple data to decide whether to make the feed change based on the impact on the bottom line.

Download the application today from Google Play store with this link http://bit.ly/poultry-farm-calc

Please do share your feedback and let us know to improve this by sending email to poultrycalc at styxtechgroup dot com

Alternate Approach to Legal Independent Election Tallying

The Uganda elections are more or less over with less than 6 hours for the Uganda Electoral Commission (EC) to announce the results for the presidential elections.

Given all the time on our hands, with no social media, the team at Styx Technology Group designed the following alternative approach to independent electoral vote tallying for future elections that provides inbuilt mechanisms for audit and verification of results.

The primary data sources for the process are:

  1. Official EC list of polling stations and voters per polling station
  2. Photos of the signed election tally sheets from each polling station. To ensure that the photos are not tampered with and provide an audit trail:
    • Each photograph has to be taken with information on the camera, the GPS coordinates of where the photo was taken, date and time when the photo was taken which is available in many cameras that share it using the Exchangeable Image File Format (EXIF)
    • Two separate photos of the tally sheets have to be taken by different cameras
    • The cameras taking equipment may be registered beforehand to provide validation of the source of the information
    • The signatures of the returning officers and stamp must be clear and visible in the photo

The architecture for the technology solution is as follows:

  1. Web based solution accessible via any browser. Due to poor Internet connectivity in many areas of the country, an Android app would be provided to assist in data collection, then data sent once the user gets into an area with Internet.
  2. The field officers who capture the photos would also be provided with an option of entering the candidate vote tallies.
  3. In the tallying center, candidate vote tallies are entered from the photos received and vote tallies entered by data clerks. In order to reduce errors the following approach would be used:
    • The clerks are randomly assigned photos as they come in
    • The tally for a station must be entered correctly by two separate data entry clerks, then approved by a supervisor. This process is formally called the two-pass verification method or double data entry.
  4. All correctly entered data is shared with the rest of the world for download and analysis.

This system is mission-critical having to be available for the entire vote counting period of 48 hours,  so the architecture includes the following paths for data collection:

  1.  Multiple access IP addresses and domains for the website in case some are blocked off
  2. Any data collected via the Android app can be sent via email to a dedicated tallying center address. To ensure that only data from the app is received and not changed in transit, encryption is used.

The inspiration came from a quote by Ghandi “Be the change you wish to see in the world”, disproving the myth that there is no local capability to design and implement such solutions and most of all that such solutions have to be complex.

Looking forward to hearing your thoughts and suggestions…
