  • Personas used for documentation and design #

    There are three primary audiences we write and design for:

    • Starburst platform administrators
    • Data engineers
    • Data consumers: analysts & scientists

    There is a single, secondary audience: “Data leaders.” This persona is largely a check writer for our purposes (VP, CDO, CIO), and does not actually use SEP any differently than the primary personas. They are included here for completeness, and should be kept in mind when creating marketing content such as case studies, white papers and ROI-focused materials.

    This document describes these audiences as personas - fictional amalgamations - that you can empathize with and solve problems on behalf of. In practice, product personas are given names, faces and backgrounds to aid in discussing their needs as if they were real people, representative of our customers.

    Primary personas #


    Data consumers - analysts and scientists #

    Data analysts and scientists will approach Starburst in very similar ways. However, their backgrounds and skill sets are different, so we will separate those out. Their pain points will be treated together.

    Chris Consumer
    Chris Consumer
    Early career
    BSc in physics from University of Toledo, currently working on online MBA

    Chris is a Business Analyst. He's responsible for delivering visualizations and reports to ensure that his leadership is making well-informed, data-driven decisions. Chris cares very deeply that not only are the right questions being asked (and answered), but that the right data is being used to answer the questions. With the wealth of data available, it can be easy to overlook and misuse data. The quality of Chris's work ultimately rests on the quality and reliability of the data he uses, so Chris keeps good working relationships with his data engineering team and often communicates discrepancies and SLAs issues to them. Chris has some solid SQL chops and is often able to prototype a new data source to be productionalized by data engineers. Chris feels that he has just the right combination of technical skills and business acumen.

    When you write, design and build for Chris, here are some of the skill sets you can expect him to have:

    • A reasonable level of skill with SQL, with some knowledge of more advanced queries
    • Limited programming skills and methodologies
    • Tells stories with data
    • Expert with data visualization tools
    • Excellent spreadsheet skills, including some modeling
    • A good ability to detect and articulate issues with data, even if he cannot remedy them or trace the cause
    Cameron Consumer
    Cameron Consumer
    Early career
    PhD in statistics, Stanford

    Cameron is a data scientist. She's responsible for creating data models and that forecast and describe the business. Cameron worries about the impact of seasonality on sales, and feels compelled to deliver models that reflect that impact with a high degree of accuracy. Cameron feels like she brings the answers to "Why?" and "How?" to the table. Her machine learning models help her find the levers that the business can pull - the "how," and her models account for why the business behaved as it did, or will. She feels more like an academic than an engineer, and is very proud of her scientific approach to business. Her digital sales data knowledge is formidable, and her reputation as an SME ensures that she has a robust stream of opportunities in her field.

    When you write, design and build for Cameron, here are some of the skill sets you can expect her to have:

    • A reasonable level of SQL skills, with some knowledge of more advanced queries
    • Reasonable programming skills
    • Expert in statistical methods and/or machine learning
    • Some understanding of code repositories
    • Competence with data visualization tools
    • A good ability to detect and articulate issues with data, even if they cannot remedy them or trace the cause

    Cameron’s and Chris’s pain points include, in no particular order:

    • Having to retrofit tools onto multiple data sources
    • Long waits for ETL to deliver useable data
    • Can’t dive into data quality issues
    • Data engineers sometimes kill their queries because of resource contention
    • Complex, periodic reports and models are often delayed past due dates

    Data engineers #

    Donna Data Engineer
    Donna Data Engineer
    Mid-career
    BSc in computer engineering, University of Illinois at Chicago

    Donna Data Engineer is responsible for designing performant data sources that can answer a broad range of business questions at XYZ, Inc. Donna found her way to data engineering through internships in college; it felt like a good blend between the technical chops required for programming jobs, and the big picture, organizational nature of data that she is naturally drawn to. As part of her job, she must understand what data is currently available from what sources, and what new data is needed to fill in any gaps. Donna has to work with stakeholders to source that new data, be it from third parties or through new log entries, message streams or product endpoints. Donna works pretty closely with data analysts and scientists, and tries to anticipate their needs in order to keep up with burgeoning data demands.

    Secondary persona - data leader #

    Lauren Leader
    Lauren Leader
    Mid-to-late career
    MBA, Haas School of Business

    Lauren is CIO at the newly IPO'ed Clouds 'R Us. She's responsible for data infrastructure, data governance and delivery, as well as enabling SOX, GDPR and CCPA compliance. Prior to stepping into her current role, Lauren was a VP of IT at Acme Corp., where she owned the budget for all data infrastructure. She calls this her "real-life MBA," because she learned the hard way from being caught off-guard by explosive growth in under-specified legacy systems in multiple budget cycles. Lauren is also sensitive to scaling, platform lock-in, and staffing around particular technologies.

    When you write for Lauren, here are some of her pain points to keep in mind, in no particular order:

    • Constantly fighting Shadow IT, up to and including small, narrow-scope one-off data warehouse solutions which she inevitably must absorb
    • Architecting around legacy systems, particularly monolithic services
    • Changing regulatory climate
    • Staffing for innovation while keeping legacy systems running and trying to automate
    • Managing, defending and demanding a budget with rapid growth
    • Balancing buy-vs-build, including for contracting services
    • Balancing private cloud vs hosted cloud solutions for cost-effectiveness, regulatory compliance and security
