Here's an example of how an engineering leader can go about managing headcount and resource planning to deliver on both the technology roadmap as well as business goals. For context, this is a resource plan for a 100-person size engineering organisation who had end-to-end responsibility for building and managing a live-streaming and video-on-demand online video platform "Delta".
I was the CTO responsible for managing everything, pretty much a CIO in my own right, overseeing: 1\ Physical Infrastructure services: Datacentres, Networking, Compute, Storage; 2\ Internet backbone transit links; 3\ Cloud integrations and peering; 4\ Telecoms integrations; 5\ Software development & testing; 6\ Video broadcast & streaming infrastructure; 7\ CDN management; 8\ Personalisation & Content Recommender systems development; 9\ Agile Program Office; 10\ Technical Operations Command Centre offering 24/7/365 first/second/3rd line support; 11\ Enterprise & Solutions Architecture; 12\ Security, Anti-piracy, Risk & Governance; 13\ Platform Intelligence Dashboards & Analytics; 14\ Vendors.
Whilst I had my own technology strategy to deliver for the underlying platform to serve the scaling needs of the business, as we were aggressively targeting a growth phase - my teams had to also continue to build out product features and enhancements for all devices we supported (sometimes the apps varying by user experience depending on the device itself, e.g. Smart TV versus iOS vs Web app), we also had to deliver new business product offerings and deliver across group-wide projects and initiatives as shared goals.
With these challenges, an engineering leader must have a firm handle on the "resource" allocation. Sorry, agile folks - I myself cringe at the mere mention of "resources" - but heck, since joining Amazon, I was amazed of how natural the term "resources" is used by management. There are two camps, people who belong to "I am NOT a resource" and "I am a resource"!!
Anyway, I digress. As a leader, you have to keep an eye on your workforce. Based on on your existing headcount allocated to you, how do you best organise your people and plan around the various delivery demands placed on your team? How do you show your stakeholders where your resources are allocated? How do you motivate for additional headcount or escalate a change of priorities if you don't have the data that accompanies your story? How do you show that although you might have 100 people under your org, the capacity for doing project work is only 80 or less, because you need to account for management, team leads, shared service work and other internal projects? See below pivot summary table:
As tedious as it might be, an engineering leader has to do some "management" work - no matter how boring it might feel. This stuff is important. The finance folks need this information. The business owners need to have a view of what impact their projects have on your teams.
A resource allocation plan can be a powerful tool - my advice - use it often, maintain it and let it become a key mechanism for you to have productive, collaborative conversations with your stakeholders.
Yes, I maintained my own list, accounting for each person in the org.
No, I don't always support the notion that people are fungible resources, can be chopped and changed or "allocated" using numbers on a spreadsheet. I also don't believe the fractional numbers help either, but they are meant to be rough allocations to help with accounting - which I'm afraid is unavoidable - part of any software managers job really.
Below picture shows what goes into headcount planning / forecasting for the year, trying to keep the headcount to 100 people due to the hiring freeze. Just imagine, a 100-person size team responsible for building the full infrastructure and consumer applications for a streaming video platform that served the whole African continent (50+ countries)! Amazon has the Frugality leadership principle - we were frugal on people but wise on partnerships, using another of Amazon's LP - Invent & Simplify.
As an experienced engineering leader, my advice to software managers: If you're not maintaining a resource allocation plan, you're missing a vital tool of software management. Be careful!!
