The How and Why of Contextual Inquiry

June 24th, 2009

A reputed agro based company recently approached us to conduct an assessment centre for their sales force. An assessment centre is a tool to systematic and objective identification of behaviours in individuals, to support actions such as selection, placement, promotion, career management and training. In an assessment centre, individuals are put through various activities, which help assessors test a set of specific competencies in individuals. These competencies could be to do with the attitude of employees, their skills set, or their domain knowledge. Usually, the set of competencies will encompass all three aspects.

The project would involve identifying competencies for the sales force, designing the assessment centres and undertaking the actual process of assessing the employees. We were quite excited because the project would essentially call for our core competencies in design and assessment.

Contextual Inquiry—what is it and what were our objectives of undertaking the process.
After a close look at the project brief, we felt the need to thoroughly understand the organization and its sales force in particular, before undertaking the task of assessing them. After a round of brain storming, we decided that a contextual inquiry of the sales force would be the best way to understand them better.
A contextual inquiry essentially involves in depth interviews with learners or assesses in this case. The findings of these interviews are meticulously collated and analysed, to arrive at inferences, which could serve as inputs for designing training, or as suggestions for the company, depending on the requirements. In this case, the findings of the contextual inquiry would help us achieve two major goals.speaking-to-a-sales-officer-and-some-farmers

1.Identify key competencies: To design the assessment centre, it was vital for us to clearly identify the competencies that they must have to carry out their existing responsibilities and to move up the value chain.
2.Understand the work environment: To effectively assess employees, it was crucial for us to make relevant activities that would test the identified competencies. And for this, we felt it was necessary to understand the work environment. This included recognising the various stake holders that the sales force contends with every day, classifying the roles played by each rank of the sales force and understanding the various factors that aid and impede their progress.
This would also serve as an important input for designing training at a later stage, after assessing the competencies of each individual.

Protocol Creation
Unlike the next stage of competency assessment, contextual inquiry is not to be seen as a platform to assess employees. While questioning respondents and while collating data, the focus must be to objectively gather and organise information, rather than documenting personal opinions and impressions. To stay focused on this goal, our first step was to create a protocol. A protocol, in this context, refers to a questionnaire that guides the interviewee, enabling us to seek relevant information.

A protocol is usually created by a process of brainstorming, after we have gathered enough information about the company and the work they do. We found it convenient to classify our queries under four broad subheads- demographic data, product knowledge, process knowledge and business acumen. The demographic data would always come first, as it helped respondents warm up to our queries.

We had a different set of questions under each of these subheads for different layers of the sales hierarchy, since each rank played a different role. This apart, we also felt the need to interview the stake holders in the business- the consumers, dealers and the distributors. Protocols were created for these respondent groups as well. In all, we had four primary respondent groups and four secondary respondent groups.

While framing questions, we ensured that each question would collect only one unit of information. For instance, we would avoid a question such as “Where were you working earlier and why did you choose to move to this company?”. This question collects two units of information— 1. details about the employee’s earlier place of work, 2. his reasons for choosing this particular company for his next career move. The problem with such a question is that you tend to lose vital information by clubbing two units of information. For instance, in this case, it may have also been relevant to understand why he chose to jump jobs, an aspect that has got lost in the process of clubbing two seemingly relevant units of data. Also, when we compile data of this nature, we expect to find patterns. For example, in this case, we might want to understand how many employees have had prior experience in the same industry. When several data units are clubbed, it becomes difficult to look for patterns of this kind.

We also took care to frame questions in direct speech. Therefore, a question would read “What are the products he sells”, rather than “What products does he sell”. This is significant because while capturing data it is vital for us to note down responses verbatim. If the question is framed in indirect speech, there is the tendency to also note down the response in indirect speech, which can lead to data loss.

On the field
The contextual inquiry took us to semi rural areas in different parts of the country. Understanding rural markets and business practices was a unique experience for us. An important aspect of our challenge was to try and relate to an FMCG business in a rural setup that was far removed from the very urban, service industry that we work in. We marveled at the manner in which stake holders in a rural business communicate with one another, secure high risk businesses and negotiate their deals. I for one was convinced about the soundness of our decision to undertake a contextual inquiry before we designed the Assessment Centres. It laid open several aspects that we may not have thought about since our reality is far removed from that of that of our respondents. at-a-chilli-farm

Following are a list of things we would recommend for an on field research:
1.Follow protocol. And this time I am referring to procedural protocol. This is all the more vital in organizations that are hierarchical, such as our client. It was virtually impossible to seek cooperation from the junior officers, unless they were personally asked to cooperate by the regional or area head. An hour long chat with the person in charge, was all it took for the entire process to be smooth. In fact, several area heads were willing to help us with aspects such as travel and accommodation once they felt included in the process.
2.Decide how much information you want to give each respondent group.For instance, the information we shared with the regional manager was different from what we shared with the sales officers, which was in turn different from what we shared with the distributors and farmers. It is also important that you decide how you would like to introduce yourself prior to an interview. Sometimes, ‘Instructional Designer’ can sound a little fancy.
3.Try and be as natural and impromptu as possible. After the first few interviews, we realised that the paper protocol we held in front of us was not only daunting but also a little distracting to the respondents. Some of them were tempted to look into our sheets to ensure that they were not being marked. Also, it helps to be informal during the interviews as it puts participants at ease. You could even speak in the local language, if the respondent is not comfortable with English.
4.We also realised that the best interviews were those that involved an informal chat over chai, or even in the car while moving from one village to another. We got the least information when we sat in a closed room and interrogated respondents.a-team-of-sales-officers
5.It is virtually impossible to deal with one respondent at a time. Often, we would have conversations with a distributor and a sales officer at the same time and would end up with information from both respondents. Strictly following the protocol can therefore impede your research at times. Use your discretion, and be alert to the possibility of getting data when you least expect it from an individual.
6.While collecting data, the focus must be on noting a respondent’s answers verbatim, rather than noting down what is correct, or more appropriate. For instance, we asked sales officers about the products they sell. While some called the products by their brand names, others referred to them by their chemical names, another group referred to the products by the local names that have stuck with the products. We noted their responses verbatim, although we were better acquainted with the brand names. While compiling data, we were able to infer as to why sales officers in certain areas called a product by the local name, while others called it by the brand name.
7.Ask for artefacts where ever possible. Artefacts could mean receipts, records, brochures, promotional material, basically any physical object that the respondent uses at work. Questions can often evolve around these artefacts.

The Kern CI travel kit
The first couple of days of the contextual inquiry had me doing the balancing act with my efforts to capture data in various forms. This is the travel kit we recommend!
1.Portable voice recorder: You can almost never note down everything a respondent says, more so in a moving car, or while trying to watch your step in a cattle farm. The smaller and less conspicuous the device, the better are your chances of capturing data without inhibiting your respondent.speaking-to-a-dairy-farmer

2.Note book: A note book is equally necessary, especially when you are conversing with multiple respondents. Make sure your note book had a hard back so you don’t need a hard surface to write on. A medium sized notebook is your best bet. A large book can be cumbersome and lose sheets of paper can be a nightmare to handle.

3.Digital camera: A basic digital camera is great to capture data and experiences. Receipts, records, products and people, there’s always something to be visually captured. The pictures came in handy while making our report for the clients. They underlined the depth of the exercise we undertook, sometimes serving as proof to our findings.

4.Large, single sling bag: A large, single sling bag is the best option to carry your camera and recorder, the protocol sheets, a book and pens. Avoid fancy bags, lap tops and double sling bags that need to be turned over to access the contents.

5.Appropriate shoes and clothing: It’s going to be hot and there will be a lot of walking to be done. Cotton clothing and comfortable shoes are what we recommend. Avoid long flowing clothes and shoes that bite. A bottle of drinking water and some cookies thrown in will also come in handy!

Data Crunching
The final phase of contextual inquiry involved compiling data, interpreting it and presenting the findings in a report. We used excel sheets to compile data, because it allowed us to spot trends amongst respondents belonging to each of our eight profiles. The trends and the interpretation of the trends were compiled into a report that we presented to our client. The report also consisted of suggestions as regards standard operational procedures and the list of competencies that we identified on the basis of our inquiry. Following is the list of competencies we identified for the sales force of the company:
1. Competencies
2. Goal Orientation
3. Planning & Organising
4. Business Overview
5. Customer Relationship
6. Communication
7. Leadership and Team Work
8. Information Management and Analysis
9. Decision Making
10. Sales Management
11. Commercial Acumen
12. Technical Knowledge

Project Bloopers
Every project has them and this one was no different, despite this being our fifth contextual inquiry and the second for a rural project, there were still some pit falls.
Understanding agriculture, poultry and dairy farming: Apparently none of us paid attention to our biology/zoology lessons in school! Our doubts ranged from confusion over the gender of broiler birds to the exact manner of referring to male cattle, to the difference between fodder and grass.at-a-poultry-farm1

Redundant questions in the protocol: After the first couple of interviews, we realised that some questions about farm care, crop cycles and feeding habits of poultry and cattle were rather redundant. Instead of wasting time asking these questions, we went ahead and modified the protocol. We could have clarified these questions from a technical expert in the field. I recommend undertaking a
pre-research with a sample participant to test out the protocol and modifying it early in the process.

Poor travel kit: Do take a good look at Kern’s CI travel kit especially if you are doing contextual inquiry in the rural areas and are constantly on the move. I made the most critical mistakes. I carried a double sling bag with a heavy laptop in it besides my other equipment and protocol sheets. I had intended to key in data while on the move, but that never really happened. It would take me a good five minutes to get all my equipment together while my colleague who was asking the questions while I captured data would march straight ahead. As a result we missed out on some pieces of data in the initial phases.

Data entry nightmares: We kept procrastinating about data entry while on the contextual inquiry and as a result we spent about three weeks just keying in data after the trip. My below average skills at excel sheets had me committing several blunders before I finally got it right. It’s a good idea to make the time at the end of each day of contextual inquiry to key in data. It also helps to have a working knowledge of excel sheets before you start using it for data entry. After a month of working with data and having a boss who loves excel sheets, I have finally reached some level of mastery with the tool.

So that has been the story so far. The next stage of the project involves designing the assessment centre to test the identified competencies. Watch out for another post to learn more about assessment centres and to find out how we go about designing them.

Three Ways to Test Effectiveness Without Learners

June 16th, 2009

Have you worked on projects where you have limited access to learners? Do you roll out the course anyway? Let us first list the reasons why learner testing cannot be conducted for all projects.

  • Learners may be situated halfway across the world and therefore, they are accessible only over phones/Skype/emails.
  • Clients may not wish to give you direct access to their learners as they are not comfortable about this.
  • Learners work on tight schedules and therefore, it is difficult to arrange learner testing.
  • There is no time to conduct a detailed learner testing (This should have been taken into account when the schedule was being drawn)

Even in these situations, you can test your course. Given below are the three techniques that you can use to test your course:

  • Recruit proxy learners
  • Expert usability evaluation and
  • Expert learning audit

Recruit Proxy Learners

Based on the learner profile, you can recruit people who have a similar profile as that of your learners. For example: Your course is designed for a bank staff in Standard Chartered Bank, England. You can recruit people with a similar profile from Standard Chartered Bank, India. The process followed in the banks will be more or else common. There are bound to be more similarities. However, you must remember that there are bound to be cultural differences. But, this technique is better than not testing it all.

Therefore, you can recruit proxy learners and conduct learner testing. Share the results with your clients and check for cultural deviations, if possible.

Expert Usability Evaluation and Learning Audit

Both these evaluation techniques have their roots in usability inspection. We have modified these techniques to suit the requirements of the learning field. If you use some other techniques, please do share. We are always eager to learn more effective ways of doing things.

How are these evaluations conducted? An expert (usability/learning) evaluates the effectiveness of the course based on a set of parameters. He/she will take the course as a learner would. He/she will click on links and buttons on the interface, try interactivities included in the course, and so on. The expert will keep an eye open for obstacles that hinder learner’s progress. These include ambiguity, functionality issues, cognitive overload, audio, and so on. Detailed reports are generated at the end of the evaluation.

What is an expert usability evaluation?

Using this technique, you evaluate the usability of an online course. An expert lists the parameters based on which the evaluation will take place. These could include:

  • Navigation: What is the primary form of navigation? Is this intuitive? This would ideally mean that we do not include ‘Click Next to proceed’ kind of instructions. The learner should intuitively know what the primary navigation is.
  • Visual hierarchy: Is the information organized in a logical manner? Eye movement is typically from left to right and from top to bottom. Are all elements positioned keeping this in mind? Will the learner know where the information starts and where it ends?
  • Accessibility of information: Are important elements places upfront? Will the learner be able to access the most important information easily? Will the learner know where he/she will find what he/she is looking for?
  • Affordance: Do buttons have the affordance of a click? Will the learner know that he/she needs to click to view? Will the learner know what is expected on an interactive screen? During learner testing, I have seen learners click images that are not clickable or miss buttons that need to be clicked. This is because the element does not have the affordance of a click. Therefore, it is important to identify such issues.
  • Fonts and font sizes: Will the learner be able to read the text easily? Do font colors hinder readability? Are these fonts and font sizes consistent across?

What is the difference between a QA and an expert usability evaluation?

  • A QA checks whether the online course maps to the signed off storyboards/wireframes. It also checks functionality, consistency, and ensures a bug-free course.
  • Expert usability evaluation, on the other hand, checks whether the elements in the course are usable. It also takes into account user experience. Does the eLearning application cater to the five principles of usability: Learnability, Efficiency, Memorability, Errors, and Satisfaction?

Let us look at an example to understand this better.

Usability comments on the Screen

A QA is more content-centric while an expert usability evaluation is more user-centric. This is the main and the most crucial difference.

What is an expert learning audit?

  • Learning objectives-content mapping: Are the learning outcomes met? Can the content be directly mapped to the learner objectives? Is there extra information? Is the information sufficient?
  • Learner-content mapping: Is the content specific to the learner profile? Is it relevant? Will it help the learner meet the learning objectives? Will the learner be able to grasp the language? Will he/she be able to relate to the examples or scenarios?
  • Learner motivation: Is the course motivating enough for the learner? Why will he/she complete the course? Will they find it interesting? Will he/she be motivated to complete an exercise? Will the learner see any benefits from taking this course?
  • Visualization: Do the visual elements aid learning? Are they generic or specific to the content? Are they used for beautification or for reinforcing learning? Are they similar in look and feel across the course?
  • Language: Will the learner understand what is written? Is there any ambiguity?

What is the difference between an ID review and a learning audit?

The most important difference is that it is conducting by a third party. By the time a course is developed, several ID reviews have already been done. The learning audit is conducted by an external person who has not been a part of the design phase. Therefore, the course is looked at by a fresh pair of eyes. The expert looks at the course solely from a learning perspective and does not take into account constraints. Several times we compromise on learning because of constraints. We also include several information because the SME/client wants us to or we are afraid of the learner missing out on information. The expert focuses on identifying the obstacles that hinder learnability. He/she can help us identify the instances where learning has been compromised. The expert also shares suggestions to rectify the issues.

Keep the following in mind if you are conducting an expert evaluation:

  • Ensure that there are no distractions. Evaluation requires a lot of concentration, else you may miss a critical issue.
  • Try everything. What if the learner were to click this? What would happen if I go here instead of there?
  • Use screen grabs to highlight issues. This is helps during fixes. The reader will not have to shuffle between a report (xls, word) and the course.
  • Ensure that you mark the issues that are repeated across the course as a global comment. However, in the report, you will have to elaborate all instances in which this issues is present. This will help the reader identify those screens when fixing.
  • If you have a set of parameters, you could check a screen for each parameter in a logical order rather than just scan a screen for issues. This way you will not miss anything.
  • Include a sound logic when highlighting an issues.
  • Include suggestions wherever possible.  Provide two or three alternatives and show a suggestion visually.
  • It can become very tedious, tiring, and repetitive. So, be prepared.

The reports generated from both expert usability and learning audio are values sources of feedback. These help identify issues that obstruct usability and learnability. The suggestions helps identify the possible solutions. Based on the feasibility, you can rectify an issues. Use these techniques to evaluate your online course. Try it once and see how much difference it actually makes. But, remember, this is still no match for direct feedback from learners.
