How to Build Your Own House Cleaning Service App That Users Will Love
Marketplace How to Build Your Own House Cleaning Service App That Users Will Love

12,896 hours is the average time each person spends tidying their homes during their lifetime. That’s 1,5 years or 77 weeks. These numbers hardly coincide with modern reality.

Business people, working moms, single-parent households, elderly people, and anyone else who can afford it, often delegate home cleaning to professionals and use the extra time for stuff they want to do.

With the growing trend of ordering services on demand, no wonder software for the house-cleaning business has already disrupted the gig economy. Due to the increase in self-employment and freelance work, the demand for digital platforms for maids will keep on growing in the years ahead.

How to Create a Human Resources Management System that Helps You Hire Faster
Business Automation How to Create a Human Resources Management System that Helps You Hire Faster

What if you could hire faster and better? What if you could get new employees job-ready in half the time?

These and other human resource process improvements are possible with a successful human resource management system (HRMS) implementation. And that is probably what you are after, otherwise, you wouldn’t be here, would you?!

The right HRM system can improve any business, but for some companies, it is a game-changer.

These are companies belonging to industries with traditionally high employee turnover rates like hospitality business, care providers, cleaning companies. These companies place a lot of premium on recruiting that is one of their key business functions (hospitality business, care providers, cleaning companies, etc.).

Companies in heavily regulated industries, where employees have to follow procedures and training (e.g. healthcare).

Does your business fall into one of the above categories? Do you feel that an HRMS is a missing component in your business to take it to the next level?

How to Develop ERP Software: the 8 Step Guide
Business Automation How to Develop ERP Software: the 8 Step Guide

50% of ERP projects fail in the first attempt.

As if that is not enough, I’ll also add that a failure of an ERP development project is not something companies can just shake off and carry on. Such projects are usually so serious, that their failure can cause a major setback for the entire company, or even its death.

How does such a bright-sided and well-intentioned endeavor, as ERP system development, end up in such a debacle? 

Here are some reasons custom ERP development projects fail (according to CIO experts and our experience):

  • Ineffective business processes - if you haven’t worked on your business processes to make them effective and unified, then no automation tool will help
  • Not including all stakeholders, especially end-users, in decision-making - everyone who is going to be using the system and affected by it, should have a say in the project
  • Failing to prioritize features - which can be another extreme of trying to please everyone, and therefore, delaying the shipment of the system by months or even years.
  • Trying to deliver the whole thing at once - long gone are the days of waterfall planning, why wait so long and spend so much just to learn that the software sucks, better to learn it early on, and fix it bit by bit.
  • Failing to get everyone onboard - a new custom ERP solution means people need to change the way they work, they’d better understand why and know what to do.
  • Forgetting to budget for maintenance - you will likely require changes along the way, not to mention that things can break, so it is wise to account for it in your budget.

In this article, we’ll talk about the 8 ways of avoiding those pitfalls, by carefully planning your custom ERP software. We share our own experiences, as well as the experience of others, so be prepared for a lot of examples.

How Does GDPR Change the Way Your Website is Developed?
Start a Project How Does GDPR Change the Way Your Website is Developed?

Since 2018, GDPR has become an indispensable condition for all companies operating in the EU and storing their customer's data electronically.  And, unless you want to pay multimillion-euro fines, you’ve got to take it seriously!

Of course, there is a silver lining and not everything is that bad. The new regulation has introduced very good privacy protection practices that will bring a lot of value to your users. So, whenever you feel intimidated, just remember that GDPR legislates common sense!

In this article, we deconstruct GDPR from the point of view of the impact on the development of your website/web app. We did our best to extract the practical steps for making your website GDPR compliant.

Creating a Call-Center Bot with AWS Connect and Amazon Lex: It Can Speak, but Does It Understand?
Technologies Creating a Call-Center Bot with AWS Connect and Amazon Lex: It Can Speak, but Does It Understand?

Speech recognition is one of the most difficult aspects of programming and, at the same time, one of the most desirable features of new-age applications. One of the potential implementations is using speech recognition in call-centers systems to automate the mundane work of operators.

The main question is how to make a machine understand natural language, transform it into text, and return an adequate response? Many development companies such as Google, Amazon, IBM, Apple, and Microsoft are now highly involved in the creation of the best mechanisms to cope with these tasks. Thus, some time ago Amazon announced a service for creating conversational interfaces for applications - Amazon Lex.

Actually, we actively use AWS products in many of our projects and know their specifics, so, in spite of the fact that Lex was still quite raw (new and poorly documented), we were determined to crack it. We hoped that this would be one more positive story that would give us more points toward our overall expertise score.

However, our experience turned out to be quite controversial. If you plan to use Lex for your automatic speech recognition (ASR) bot, you may find it helpful to read this article. We would like to caution you.
