      <image:title>Typetalk, a Business Chat App: Usability Testing - The Problem</image:title>
      <image:caption>In the last study, participants had difficulty navigating to their desired “chat room”. The chat room list was frequently reordered, as it was designed to sequence chat rooms according to last activity. As a result, it was difficult for users to predict where a desired chat room would appear on the list and forced users to do a tedious search of the list each time they needed to communicate in a chat room.</image:caption>

      <image:title>Typetalk, a Business Chat App: Usability Testing - Key Findings: Adding Chat Rooms to Topic Groups</image:title>
      <image:caption>Participants did however encounter friction in adding topics to topic groups. Many expressed it as a tedious process that could be made easier by drag-and-drop interaction, where users could drag a topic into a group, instead of following a series of tedious steps.</image:caption>

      <image:title>Typetalk, a Business Chat App: Usability Testing - Participant Recruitment</image:title>
      <image:caption>Recruitment for this project posed a minor challenge. We wanted feedback from both existing and prospective customers. However, Typetalk is Nulab’s newest product and didn’t have an easily accessible pool of customers from which to recruit. After some discussion, stakeholders and I concluded that Nulab employees could be leveraged. Nulab employees were screened along behavioral characteristics to ensure we received representative feedback.

      <image:title>Typetalk, a Business Chat App: Usability Testing - The Prototype</image:title>
      <image:caption>2 solutions were tested for this study. The first was a “pin” feature that allowed users to “pin” a topic to the top of the chat room list, allowing them to prioritize specific chat rooms for easy navigation. The second was a “grouping” feature that allowed users to group multiple chat rooms, providing a logical, user-organized chat room list.</image:caption>

      <image:title>Cacoo, a Diagramming Tool: Personas - Project Goals</image:title>
      <image:caption>This project followed Cacoo’s journey mapping study. Post-study discussions revolved around addressing the underserved needs and usability challenges that were discovered during that research. In order to cement our foundational understanding of users, we decided to build personas, incorporating what we had learned from journey mapping. Specifically our goals were to: Create personas for the following phases containing underserved needs and usability challenges uncovered during journey mapping Diagramming: Visualizing Ideas Sharing &amp; Presentation Viewing &amp; Collaboration</image:caption>

      <image:title>Cacoo, a Diagramming Tool: Personas - Workshop</image:title>
      <image:caption>Once the journey map was reviewed, the team was split into 2 groups to build 2 personas. The first persona would describe users during the “Diagramming: Visualizing Ideas” phase and “Sharing &amp; Presentation” phase. The second persona would describe users during the “Viewing &amp; Collaboration” phase. For each persona each team built a generalized profile that contained the following persona info: Job role Workplace Software &amp; Hardware utilized Motivations Goals Behaviors Quote</image:caption>

      <image:title>Cacoo, a Diagramming Tool: Journey Mapping - Key Findings: Identifying Underserved Needs</image:title>
      <image:caption>One part of the journey in particular, was key to identifying underserved user needs and informing new features. At the time, it was obvious that diagramming was a core phase of the user journey, but after conducting this research, we realized that we were missing a bigger story. Visualizing Ideas In that bigger story, the first thing we realized was that Diagramming wasn’t just creating a flowchart or some other diagram, but it was a way for users to visualize some work related idea or concept.  So for example, if the user was an IT person, perhaps they were tasked with making adjustments to the hardware network. In that scenario, they used diagramming as a way to illustrate their solution. Sharing &amp; Presentation In continuing that story, they then might need to communicate their solution to a broader team. So they took actions like:  Sharing access so that their colleagues could view diagrams Adding diagram images to reports &amp; slide decks, again to share access with their colleagues And using the presentation feature, to share their diagram in a group setting Viewing &amp; Collaboration The last thing that we learned about this story was that users often revisited already created diagrams to:  Reference for some later work Continued to actively discuss it, sometimes leaving comments for others to see So in deepening our story of the user journey and adding these 2 latter phases in particular,  we revealed product opportunities that became core focuses in evolving the product.</image:caption>

      <image:title>Cacoo, a Diagramming Tool: Journey Mapping - User Interviews: Exploration of Users, their journey, needs &amp; challenges, and other context</image:title>
      <image:caption>Research began with user interviews, designed to gather background details about each person and the context in which they diagram. Each interview explored the topics below, uncovering data around each participant’s goals, motivations, challenges, physical environment and social environment. Their role and job responsibilities Their company’s products and services Their team’s structure and dynamics Work scenarios that lead to diagramming The purpose of their diagramming Needs that they have while diagramming Challenges that they face while diagramming</image:caption>

      <image:title>Cacoo, a Diagramming Tool: Journey Mapping - Goals &amp; Deliverables</image:title>
      <image:caption>Early conversations with stakeholders, revealed a lack of solid understanding for Cacoo’s users, their context around diagramming, and what they need in a diagramming product. Before jumping into a redesign, we set up an exploratory study to find out more and provide a starting point of data to investigate further.  We specifically aimed to answer: What does the end-to-end journey of users engaging with diagramming software look like? What needs and challenges do they have along the journey? and aimed to deliver: Journey Map Needs &amp; challenges / Product opportunities Product direction Future areas of investigation</image:caption>

      <image:title>Cacoo, a Diagramming Tool: Journey Mapping - Key Findings: Usability Opportunities</image:title>
      <image:caption>In terms of the interface itself, 2 themes appeared during research that also guided the products future direction. Navigation The first theme had to do with navigation issues. When participants were asked to create a diagram, they had struggled in getting past initial steps.  They couldn’t discern how to engage with the interface, because the buttons were small and some icons didn’t communicate their functionality well. In addition, the menu in its entirety was complex., There were 3 menus with various buttons, making it difficult to sort through. Look &amp; Feel The second theme had to do with the aesthetics of the interface.  Participants often expressed that the interface looked and felt old.  One person said that it looked like Windows XP.  Also, some expressed to the effect that the old aesthetics created negative expectations and turned them off to wanting to use the product further. So in addition to surfacing the underserved needs mentioned earlier, this research also helped us to uncover these usability related product opportunities.</image:caption>

      <image:title>Cacoo, a Diagramming Tool: Journey Mapping - Next Steps</image:title>
      <image:caption>This initial project was a great, first step for an organization that had very little understanding of what their users experience while diagramming. The journey map and the learnings it contained provided a robust overview that helped identify product opportunities and guide future direction. Following this project, we focused on investigating those opportunities further.</image:caption>

      <image:title>Cacoo, a Diagramming Tool: Journey Mapping - Stakeholder Alignment</image:title>
      <image:caption>While interviews and testing were conducted, stakeholders observed live or at their discretion via recorded sessions. For each session, stakeholders captured data by taking notes about what was discussed. Session Debrief Following each session, a session debrief was held to begin building our journey map, leveraging data from each research session. Workshops Following the completion of all the research sessions, a workshop was held to review the entirety of collected data and complete the creation of our journey map.</image:caption>
