The Context Of Design Thinking And Its Application In Employee Skill Training

Design thinking is a crucial pillar in today’s problem-solving imperatives. In fact, it is being pursued as a unit course in various institutions across the globe, thus underlying its importance in aiding objective human thinking. It’s not a specific property for designers. Far from it, it has emerged as an innovative solution-seeking tool for all great inventors and innovators.
 
By description, it is a design methodology used for tackling complex problems that are virtually unknown or ill-defined, through a careful evaluation of the human needs involved, understandably restructuring the problem, by brainstorming to create many solutions, and by adopting a direct approach in testing and prototyping. It helps us come up with creative ways to solve nagging problems that stem from us and especially in the workplace setting.
 
The ‘overwhelmed/overburdened employee’ is a common term in HR offices across many organizations in the world. Employees are faced with a huge challenge in regards to coping with fast-paced technological and office changes in the working environment. This had led to a massive stagnation in productivity, prompting HR heads to look for new ways to reduce their employees’ stress and workload.
 
While evaluating many options, this model of thinking has posed as a helpful tool for HR managers when dealing with their vexed employees. IT training, in particular, has helped shape the productive realms of many companies out there.
 
Let’s explore how this thinking domain can be used to plan employee skill training:
 
Empathize
If you want to show concern for your employees, first empathize with their situation. Seek to understand the needs of the employees deeply, what they lack, what they need, and the challenges that they are likely facing. This will act as the basis of plotting the problem and working on the next phase of solving it.
 
You can collect data in this phase through empathy maps and journey maps. In the latter, you endeavor to steadily track the day-to-day activities and tasks of employees. This is achieved through observations or structured interviews. In turn, it aids in elevating the thinking process.
 
Through empathy maps, you ponder on collected findings and synthesize them keenly. Here, you seek to establish how an employee is thinking, their feelings, and insights into the probable root cause of the problem.
 
Define the Problem
After a comprehensive analysis of the collected data; the problem definition phase should follow. The idea here is to locate the underlying root of the problem concisely. HR should seek to utilize an analysis framework to help address problems affecting the holistic being of all employees. Therefore, each issue would require a list of underlying causes: lack of motivation, lack of knowledge/understanding, or just lack of skill.
 
Once the root cause(s) are clearly defined, a clear problem statement should be drawn up alongside performance goals that are firmly based on actual drivers. 
 
Think Solely About Employee-Based Solutions (iterative learning)
Conventionally, customers are at the heart of every organization’s dealings. They inspire and drive the company’s objectives because they are crucial in profit making. However, employees have greatly suffered while working ‘behind the scenes.’ Such situations have led to employees feeling discontent and work under immense pressure, which inevitably leads to underperformance. To avoid this, the experimental learning concept can be utilized by HR offices to engage employees more by creating solutions that directly suit the situations they encounter daily.
 
Here, trainers are removed as the center of focus. An iterative ‘reflection’ cycle is established to tap continuous employee feedback in a bid to sharpen their skills. This method helps employees adapt to new technology through a well established IT consulting network. In the long run, employees don’t forget how they handled a particular problem, and this effectively raises a firm’s productivity.
 
Support Employee Tasks with Simple Technology (Ideate)
The simplest way to support employee-working experience is by not sidelining them unprepared with changing technology processes. As an HR Manager, fully engage your employees when transitioning to new tech by making use of effective training or consulting services. Specific training needs can be assessed and addressed within the organization or with a third party industry expert. 
 
According to Deloitte’s 2016 Global Human Capital Trends Report, design thinking was isolated as crucial in crafting the employee experience. 79% of those interviewed identified it as imperative. However, almost a similar percentage agreed that a lot of compliance programs and training are still based on outdated modes of meetings and processes.
 
The report also recommended the need to put necessary consideration on employees through proper IT training for far colossal efficiency. One way to make this work is by drawing a connected roadmap of skills and information needed at certain work intervals. Shedding off overwhelming and irrelevant amounts of data for new employees is vital in retaining their concentration and output. What’s more, a customizable app can help employees undertake appropriate tasks at the specified time, thus resulting in higher revenue for the long term.
 
Implementing an Intuitive Tech Learning Approach (Ideate)
The basis of this argument is that not every employee is the same. All of them are differently gifted and shouldn’t be forced to use one inflexible technology or system that doesn’t cater to their individual needs in a buzzing work environment. This mode of critical thinking brings to life personas such that fictive employees representing a defined group of external employees are drawn up. In this set-up, the personas should be able to learn and work efficiently within their own small environment while quickly utilizing their own skill set and the required information to make things work.
 
An HR manager can replicate this working scenario through the use of role-plays. This can be achieved by conducting short-term soft skills training sessions to sharpen their ability to handle similar situations. In the case of new technology, video-replays on how to use it in a one-on-one customer scenario can help relieve the pressure and spur the employee to be more productive.
 
Prototype and Testing
Here, the HR Manager should run a couple of tests to ensure whether the desired model of skill training is working. One way to get started is by crafting a simple prototype of the technology required, probably as a single module to establish its viability.
 
The new technology should be vigorously tested during prototyping to pinpoint any leaks, disjoints, or performance issues. Structured walkthroughs can be implemented to help employees navigate the solution through proper IT training sessions.
 
What’s more, HR should conduct sessions to get the employees’ views, emotions, or feelings regarding the new solution. In case of any cause for concern, the prototype should be improved until it meets the intermediate needs of its users.
 
Iterations are also a common occurrence in this phase. Refinements and alterations are curved out to make sure that the final thing suits every employee in some understandable capacity.
 
Wrapping Up
Design thinking is crucial in any organizational setting in making sure that employees sync properly with the technology in place. This will go a long way in improving their productivity.

 

I suspect that many of you are familiar with the term "hard coding a value" whereby the age of an individual or their location is written into the condition (or action) of a business rule (in this case) as shown below:

if customer.age > 21 and customer.city == 'denver'

then ...

Such coding practices are perfectly expectable provided that the conditional values, age and city, never change. They become entirely unacceptable if a need for different values could be anticipated. A classic example of where this practice occurred that caused considerable heartache in the IT industry was the Y2K issue where dates were updated using only the last 2 digits of a four digit number because the first 2 digits were hard-coded to 19 i.e. 1998, 1999. All was well provided that the date did not advance to a time beyond the 1900’s since no one could be certain of what would happen when the millennia arrived (2000). A considerably amount of work (albeit boring) and money, approximately $200 billion, went into revising systems by way of software rewrites and computer chip replacements in order to thwart any detrimental outcomes. It is obvious how a simple change or an assumption can have sweeping consequences.

You may wonder what Y2K has to do with Business Rule Management Systems (BRMS). Well, what if we considered rules themselves to be hard-coded. If we were to write 100s of rules in Java, .NET or whatever language that only worked for a given scenario or assumption, would that not constitute hard-coded logic? By hard-coded, we obviously mean compiled. For example, if a credit card company has a variety of bonus campaigns, each with their own unique list of rules that may change within a week’s time, what would be the most effective way of writing software to deal with these responsibilities?

Checking to see if a directory exists and then creating it if it is not present requires a few lines of code.  Isn't Python great. enlightened  Begin by importing the os module and use the exists and makedirs functions.

 

import os

if os.path.exists(somedirectory):
   os.makedirs(somedirectory)



data dictionary workThe mainstay of a corporation is the data that it possesses. By data, I mean its customer base, information about the use of its products, employee roles and responsibilities, the development and maintenance of its product lines, demographics of supporters and naysayers, financial records, projected sales ... It is in the organization of this data that advancements to the bottom line are often realized i.e. the nuggets of gold are found. Defining what is important, properly cataloging the information, developing a comprehensive protocol to access and update this information and discerning how this data fits into the corporate venacular is basis of this data organization and may be the difference between moving ahead of the competition or being the one to fall behind.

Whenever we attempt to develop an Enterprise Rule Application, we must begin by harvesting the data upon which those rules are built. This is by no means an easy feat as it requires a thorough understanding of the business, industry, the players and their respective roles and the intent of the application. Depending upon the scope of this undertaking, it is almost always safe to say that no one individual is completely knowledgeable to all facets needed to comprise the entire application.data dictionary

The intial stage of this endeavor is, obviously, to decide upon the intent of the application. This requires knowledge of what is essential, what is an add-on and which of all these requirements/options can be successfully implemented in the allotted period of time. The importance of this stage cannot be stressed enough; if the vision/goal cannot be articulated in a manner that all can understand, the knowledge tap will be opened to become the money drain. Different departments may compete for the same financial resources; management may be jockeying for their day in the sun; consulting corporations, eager to win the bid, may exaggerate their level of competency. These types of endeavors require those special skills of an individual or a team of very competent members to be/have a software architect, subject matter expert and business analyst.

Once the decision has been made and the application development stages have been defined, the next step is to determine which software development tools to employ. For the sake of this article, we will assume that the team has chosen an object oriented language such as Java and a variety of J EE components, a relationsional database and a vendor specific BRMS such as Blaze Advisor. Now, onto the point of this article.
