​​Identity & Access Management Implementation Plan (Step-by-Step)

Identity and Access Management sits at the center of everything you do: every login, API call, and approval runs through it. The landscape is already chaotic: non-human identities outnumber employees by 80 to 1, from bots to service accounts.

Companies today struggle with permissions across multiple clouds and identity providers. Wing it with ad-hoc scripts and spreadsheets, and you get orphaned accounts, failed audits, and breaches that end up in emergency board meetings.

 A structured IAM implementation isn't bureaucracy. It's the difference between controlled deployment and chaos.

Here’s how to get there.

Phase 0: Kickoff & Guardrails (Days 0–7)

Before you draw a single architecture diagram, get the right people in one room. Access is scattered across multiple clouds, and the IAM stakes are too high for a shaky start.

Identity sprawl, multi-cloud complexity, and orphaned accounts have killed plenty of IAM projects. You don't want to join that list.

Your first job is alignment: scope, ownership, success metrics. Name an executive sponsor, define which apps and user groups make the first cut, and agree on how you'll measure "done." Get those basics into a RACI and project plan so IT, Security, HR, Legal, and Finance all know their role.

Teams often struggle to coordinate across departments during IAM kickoff. Siit helps here by embedding request intake and approval workflows directly into Slack or Teams, ensuring that project sponsors, IT, and HR remain aligned without relying on scattered email threads.

Pick metrics that matter without crushing morale: MFA coverage percentage, SSO coverage, join-move-leave cycle time, and orphaned account count. Start small, track weekly, let wins build momentum.

Common ways this goes wrong? Vague scope, missing sponsors, and change-management theater. Skip the glossy presentations. Schedule tight stand-ups, create a risk register everyone can comment on, and get written sponsor sign-off before day seven.

You're not implementing software, you're changing how people work. Get that foundation right, or spend months fixing it later.

Step 1: Current-State Discovery (Weeks 2–3)

You can't fix what you can't see. Before touching a single policy, you need a rock-solid map of every identity, system, and risk hiding in your stack. The stakes remain high: without proper discovery, you're practically guaranteed to miss a bot, API key, or forgotten contractor login.

Your goal for the next two weeks: build a source of truth you'd bet your audit on. Start by pulling raw data from HR, Active Directory, SaaS logs, and cloud consoles. Shadow IT will surface fast: look for apps with no official owner or sign-in counts that dwarf their user roster. Those are your first red flags for orphaned accounts and privilege creep.

Capture what each feed actually tells you:

• HR records give you who
• Directories tell you where they authenticate
• Application reports reveal what they can do

Stitching those together forms your identity data model. Document every JML handoff that relies on a Slack ping or spreadsheet: those manual steps become tomorrow's automation backlog.

Siit eliminates this manual tracking by centralizing joiner–mover–leaver workflows inside Slack/Teams. It integrates with HRIS systems like BambooHR and identity providers such as Okta or Entra, so every handoff is logged and automated rather than improvised.

Keep the output tight: 

• System catalog with owners and authentication method,
• Draft identity data model showing joiner-mover-leaver flows
• Gap analysis highlighting shadow IT and multi-IDP overlaps
• Architecture diagram everyone signs off on

Discovery isn't glamorous, but skipping it guarantees rework. Use lightweight tools, such as directory exports into Google Sheets, cloud asset scanners, even a one-off Python script to reconcile data across on-prem and multi-cloud. Once the diagram is up on the wall and every owner nods, you're cleared to design the future-state architecture without unpleasant surprises.

Step 2: Target Architecture & Control Design (Week 4)

You get one shot at the blueprint. This week, lock in an IAM architecture that won't crumble when you add a new cloud or double headcount. Write down the objective: every identity, be it a human, bot, or vendor authenticates through a single flow, gets the right access automatically, and can be yanked in seconds.

Start with your identity provider and MFA patterns. In multi-cloud shops, 65% of teams say juggling multiple IdPs is their biggest pain point. Collapse that sprawl now with SAML or OpenID Connect federation across AWS, Azure, and the SaaS you already pay for.

Decide how users prove who they are. Push-passcode MFA is table stakes. Start piloting passkeys or WebAuthn so you're not ripping out passwords later when phishing gets even easier.

Sketch your authorization model. Keep roles tight, hierarchical, and business-speaking—finance-analyst, not "role_42." Follow least-privilege patterns and validate with your managers before baking them into code. Edge cases happen. Park them in a documented exception process instead of inventing one-off roles that snowball into role explosion.

Before the week ends, add automations: HR-driven provisioning, just-in-time elevation for admin tasks, and break-glass access that logs every keystroke. Package it all into a control matrix and get security sign-off.

Step 3: Tooling & Integration Plan (Week 5)

Pick the wrong stack now and you'll spend the next year writing glue code. The goal this week is simple: decide what you're buying, what you're building, and in what order everything plugs together.

This is what you need to do: 

• Lock down your identity backbone. Most teams land on Okta or Microsoft Entra ID, while smaller orgs go with JumpCloud for an all-in-one directory. Remember that multi-cloud chaos will bite you later if you don't consolidate now.
• With your core platform chosen, confirm ready-made connectors exist. Prioritize apps in waves: life-or-death systems first (payroll, production cloud), then daily-use SaaS (Slack, GitHub), and finally long-tail, low-risk tools. Wave planning keeps you from trying to integrate everything at once and gives execs quick wins to show progress.
• Test everything. Build a runbook that hits every control path: SSO handshake, MFA prompt, just-in-time provisioning, deprovisioning. Automate these checks through the platform's API so regression tests run on every connector change. You'll thank yourself when pilot sign-off comes around.
• Finish the week with three artifacts: integration runbook, app backlog mapped to waves, and test plan. Once your sponsor signs off on these, the pilot scope is locked and you can move forward with confidence.

Siit’s no-code editor accelerates integration testing by letting teams map workflows visually. Instead of writing glue code, you can configure HR triggers (like a BambooHR update) to launch provisioning or deprovisioning across identity systems instantly.

Step 4: Policy & Governance (Week 6)

By week six you're ready to turn all those design decisions into rules people can actually trust and auditors can trace. Without written policies, all controls you built are just suggestions. Governance closes that gap and keeps you out of headline-worthy mistakes.

Your objective is simple: lock the guardrails in writing so every login, role change, and emergency override is both enforceable and auditable. Draft the policies, set review cadences, and map the approval chain. You need signed docs, a living review calendar, and clear approvers before moving on.

Start with your biggest blind spots. Identity analytics gaps still trip up most teams, leaving zero-trust dreams stuck in PowerPoint slides. Written policy is where you force that consistency across cloud providers. 

Match cadence to risk: high-impact roles get monthly reviews, everything else can wait a quarter. Some industries, such as healthcare (HIPAA) and finance (GLBA, SOX), often need tighter timelines, so bake those into the calendar upfront. 

When legal worries about usability, remind them that clear MFA exemptions for on-call doctors or trading-floor outages keep both security and patient-care/broker-compliance happy. Bring draft policies to those teams early, iterate fast, and walk out with signatures. Once the ink's dry, everyone knows the rules and you can start automating against them.

Step 5: Build JML Automations (Weeks 7–8)

JML automation kills the two biggest identity headaches: privilege creep and orphaned accounts. Every manual click adds to that mess and creates opportunities for human error.

Start simple: wire your HRIS into your identity provider so new hires get baseline access automatically. With Siit orchestrating these handoffs, HR-triggered events automatically update ITSM, IAM, and HRIS systems. For example, a contractor exit flagged in BambooHR can trigger Siit to remove Okta access, revoke Slack permissions, and notify managers, all in real time.

Movers come next. Map title changes to role changes so that promotion to manager doesn't accidentally give someone access to payroll data. We've seen this break budgets and create compliance nightmares.

Leavers are where most teams get things wrong. The moment HR marks someone as terminated, every system should know. Lingering accounts are how attackers slip in weeks after someone's gone.

Contractors need their own lane. Give them time-boxed roles with auto-expire dates. If they need more time, they'll ask. Better than you reading about your forgotten contractor account in a breach report.

Test everything in sandbox first. Simulate hires, transfers, exits until nothing lands in your manual queue. When your JML audit shows zero manual fixes needed, you're ready.

Step 6: Pilot: SSO + MFA + Provisioning (Weeks 9–10)

Before you flip the big switch, run a two-week dress rehearsal. A tight pilot lets you prove that SSO, MFA, and automatic provisioning actually work together, without melting Slack channels or locking someone out of payroll the night before close.

First, lock your objective: validate the complete system with a small, mixed group. Hand-pick fifty users across departments, time zones, and device types (yes, throw in a couple of service accounts). Include at least one power user of every critical app in wave one; that surfaces edge-case permissions early.

Next, your actions. Enforce MFA for the pilot group, wire each test app behind SSO, and let HR triggers auto-provision new roles. Hybrid work means people will log in from coffee shops and corporate VPNs so you want both scenarios in scope.

Keep score with two deliverables: a pilot report and a fix list. Your acceptance bar is simple: target metrics met (zero lockouts, 100% MFA enrollment, provisioning under five minutes).

Common pitfalls? Password hangovers. Users cling to old credentials even as you push toward passwordless options now gaining ground. Combat that with micro-training and real-time support chat.

During the pilot, run tabletop exercises. Simulate a lost phone, a sudden off-boarding, a break-glass admin request. Each drill exposes policy gaps before auditors or attackers do. Capture feedback fast, patch configs faster, and you'll roll into the full rollout with confidence instead of crossed fingers.

Step 7: Wave Rollout (Weeks 11–12+)

Your pilot worked. Now scale it across the company without breaking daily operations.

Roll out department by department; it's the same phased approach that works for any major system integration. Each wave builds confidence and lets you fix issues before they multiply. Track important metrics such as MFA coverage percentage and SSO adoption percentage. If either stalls, promptly investigate in accordance with your organization's risk posture and IAM best practices.

Map every legacy authentication method before you start: password databases, hard-coded LDAP binds, local admin accounts. Give each a firm decommission date. Teams that skip this step end up managing duplicate login systems and failing audits.

Expect pushback. Someone will insist they "need the old VPN for one critical report." Counter with data from your adoption dashboards.

Keep security tight during migration. Maintain conditional access policies, review logs continuously, and implement adaptive account lockout mechanisms based on failed MFA attempts to balance security and usability. If your coverage and efficiency targets stay green, advance the next wave. If not, pause and fix issues first.

Run daily check-ins during active waves. Fast feedback loops catch problems while they're still manageable. When people report issues, prioritize fixes that affect multiple users.

Wave by wave, you'll replace authentication sprawl with unified identity management. Your audit team can finally stop holding their breath.

Step 8: Access Governance & Reviews (Month 4)

You've got SSO, MFA, and automated provisioning running. Now comes the hard part: making sure people only keep the access they actually need.

Here's the reality: automated identities keep growing, and every bot, service account, and contractor adds complexity. Without regular cleanup, your clean IAM implementation becomes a mess of abandoned permissions.

Start access reviews the moment your provisioning stabilizes. Run them quarterly to catch bloated permissions early and keep auditors happy.

Pick one application stack for your first review. Send managers a simple list of their team's access and ask for a yes/no decision on each item. That's it. Automate the follow-up emails because manual tracking falls apart fast.

Feed approval decisions directly into your control dashboard. Schedule monthly check-ins with Security to review findings and publish quarterly reports.

Enforce segregation of duties automatically. No one creates and approves payments, for example. Build these constraints into your roles and flag violations immediately. When violations surface, fix them within 24 hours or log a time-boxed exception with executive approval.

You'll know governance is on the right track when every reviewer completes their quarterly review and your findings show zero critical violations, though true effectiveness is measured by a broader set of metrics. At that point, governance isn't a task you do. It's built into how the system works.

Siit supports governance by embedding lightweight approval workflows into Slack/Teams. Managers can complete access reviews without leaving their daily tools, while Siit logs every action for auditors in connected systems like Jira or ServiceNow.

Step 9: Monitoring, Metrics & Improvement (Ongoing)

Once the rollout dust settles, the real work begins: keeping everything clean, fast, and ready for tomorrow's threats. Track four numbers religiously:

• MFA coverage
• SSO coverage
• Join-move-leave cycle time
• Orphaned account count

These metrics tell you in seconds whether identity sprawl is creeping back in or if you've finally broken the "create-but-never-delete" habit. They also give leadership a clear story: fewer stranded accounts equals lower breach risk and less admin time wasted.

Dashboards only matter if you act on them, so set a rhythm. Every week scan logs for weird access patterns; every quarter run a full access review and publish a control-health report. That rhythm turns raw data into decisions, like retiring a role that's been unused for 90 days or expanding MFA to that last stubborn legacy app.

Keep your playbook alive. New cloud connectors drop, regulations shift, and passkeys replace passwords. Schedule roadmap reviews twice a year, budget for incremental upgrades, and keep training fresh so your team spots weirdness before an attacker does.
