A 5-step Challenge Administration Framework for Information Science
This text is a part of a bigger collection on Full Stack Information Science. Within the earlier publish, I launched the thought of a full-stack information scientist and the 4 hats it entails. On this article, I’ll talk about the primary of those 4 hats — the mission supervisor (PM). Whereas there are numerous methods to method information science mission administration, right here I suggest one attainable framework and the PM’s function in executing it.
Information science initiatives typically contain creating machine studying (ML) fashions to resolve enterprise issues. Whereas this will likely appear commonplace in enterprise at this time, it nonetheless comes with a number of dangers.
Particularly, creating ML fashions is inherently unsure, technically demanding, costly, and time-consuming. These dangers encourage mission administration frameworks particularly designed for information science initiatives in thoughts.
Right here, I’ll describe one such method and break down the important thing contributions of a mission supervisor on this context.
A 5-Step Challenge Administration Framework
The method I like to make use of for information science initiatives is printed by the 5-step framework illustrated beneath.
Digging deeper, listed below are a couple of key actions for every part.
- Part 0: Downside Definition & Scoping — Formulate the enterprise downside. Design the information science answer. Outline mission milestones, duties, and success metrics. Key function: Challenge Supervisor
- Part 1: Information Acquisition, Exploration, & Preparation — Consider out there information. Purchase and discover information. Develop information pipelines. Key roles: Information Engineer, Information Scientist
- Part 2: Answer Growth — Develop ML answer. Consider answer validity and worth. Iterate with stakeholders and revisit previous phases as wanted. Key function: Information scientist
- Part 3: Answer Deployment — Combine answer into real-world enterprise context. Develop answer monitoring pipeline. Key roles: ML Engineer, Information Scientist
- Part 4: Analysis & Documentation — Consider mission outcomes. Ship technical documentation and consumer guides. Mirror on classes discovered and future work. Key function: Challenge Supervisor
An essential level right here is that information science initiatives typically don’t progress linearly by every of those phases. Fairly, some quantity of iteration is required by key suggestions loops. Listed below are a couple of examples of what this may look like.
- Part 1 → Part 0: When exploring the out there information, it turns into clear that key info shouldn’t be out there, and the mission plan should be revisited.
- Part 2 → Part 1: After coaching a handful of fashions, it’s found that an exception was not correctly dealt with in information preparation.
- Part 2 → Part 0: Preliminary fashions don’t reveal robust predictive efficiency, which requires reevaluating the mission’s worth.
- Part 4 → Part 0: Each mission has its alternatives for enchancment. Upon completion, groups can consider these alternatives and kick off one other mission, beginning with Part 0.
Position of the Challenge Supervisor
The mission supervisor (PM) is in the end chargeable for a mission’s success. If the mission is late, it’s on the PM. If prices exceed estimates, it’s on the PM. If the worth doesn’t meet expectations, it’s on the PM.
Whereas this duty includes a various vary of duties from a number of contributors, one key determinant of a mission’s success is the PM’s execution of Part 0 (as described above).
Part 0 units the muse of a knowledge science mission. Simply as a poorly constructed basis will lead to a troublesome development mission, a poorly executed Part 0 will lead to a troublesome information science mission.
The three key parts of Part 0 embrace Downside Prognosis, Answer Design, and Implementation Plan [1].
1) Downside Prognosis
Of the three parts, that is probably the most essential as a result of for those who get this incorrect, you possibly can spend a variety of money and time fixing the incorrect downside (i.e., little worth is generated). Regardless of its significance, many are inclined to gloss over (if not skip completely), taking the time to cease and take into consideration the enterprise downside.
Simply as a health care provider interviews a affected person to provide a prognosis, a PM interviews stakeholders to higher perceive the enterprise downside and determine the foundation trigger. Though there are lots of methods to do that, I wish to hold issues easy and give attention to asking two key questions.
- What downside are you attempting to resolve? — that is all the time one of the best start line for these conversations [1]
- Why is that essential to the enterprise? — this will kick off a collection of 5 why-based inquiries to get to the issue's root trigger (see Toyota’s 5 Why’s method) [2]
One of many PM's most essential abilities is successfully collaborating with stakeholders to grasp their issues. I talk about this additional in a previous article.

2) Answer Design
As soon as the enterprise downside is clearly understood, the subsequent step is to outline tips on how to clear up it. Numerous options at varied ranges of complexity can tackle any given downside.
For example, if buyer churn is excessive as a consequence of a gradual onboarding course of, some potential options may very well be eradicating pointless onboarding steps, analyzing the place drop-off happens and remodeling that step, customizing onboarding primarily based on buyer info, and so on. Discover that these options could not require machine studying (and that’s okay).
Suppose, after in depth back-and-forth, the stakeholder needs to maneuver ahead with creating a customized onboarding expertise primarily based on buyer profiles. Whereas this narrows issues down, this answer can nonetheless be applied in some ways. Due to this fact, the PM should use their judgment to suggest an answer primarily based on stakeholder conversations, comparable trade initiatives, and out there assets.
3) Implementation Plan
The ultimate factor of Part 0 is translating the proposed answer right into a concrete mission implementation plan. This plan consists of two key items: a mission roadmap and the mission necessities.
A mission roadmap consists of key mission milestones. I wish to base these milestones on Phases 1–4, as described above. Every part consists of duties assigned to a specific function (e.g., information engineer, information scientist, or ML engineer) and a due date [1].
Challenge necessities specify all the mandatory assets for implementation, together with information necessities, key roles, software program instruments, and compute infrastructure.
Case Examine: Semantic Search over YouTube Movies
I’ll stroll by Part 0 for an instance case examine to solidify these concepts. Whereas that is meant to be instructive, it’s a actual mission I’ll implement (and doc) in future articles of this collection.

Background
I share content material about information science and entrepreneurship on platforms like Medium and YouTube. This serves as a approach for me to construction my studying and doc my journey as an entrepreneur.
A pure consequence is that my content material spans varied matters, attracting a various viewers of learners, entrepreneurs, and enterprise leaders. Whereas this variety enriches the training expertise, it could possibly additionally current challenges for viewers members navigating totally different matters throughout a number of platforms.
Downside
Given the varied vary of matters I cowl, viewers members could face difficulties in effectively finding content material that aligns with their particular pursuits or present academic wants. This could result in decrease engagement and probably inhibit viewers progress as customers could hand over or miss out on related content material.
Answer
To reinforce content material discoverability and consumer engagement, I suggest creating a centralized repository the place all my content material from Medium and YouTube is accessible. This platform will characteristic a search perform that enables customers to simply discover particular matters, reply information science questions, and discover entrepreneurship insights. The search performance will probably be designed to grasp pure language queries, making it simpler for customers to seek out what they want with out navigating by totally different platforms.
As a primary step in direction of creating this centralized repository, I’ll develop a proof-of-concept net web page that may index all my YouTube movies and incorporate a search perform that permits viewers to find movies by particular matters or questions. This preliminary part will assist assess the feasibility of the search expertise and lay the groundwork for an MVP model of the centralized repository.
Implementation Plan
What’s Subsequent?
Given the distinctive challenges of constructing information science options, managing these initiatives requires particular consideration. Right here, I described one attainable framework for doing this and break down the mission supervisor's key contributions.
Within the subsequent article of this collection, we are going to transfer on to Part 1 and stroll by a typical information engineering workflow utilizing the above case examine as a information.
