Tower Crush operates on a dual-layer strategic system combining tower merging mechanics with real-time wave defense. The core loop revolves around placing identical tower units on a grid battlefield, then dragging one onto another to create a higher-tier tower with exponentially increased damage output and firing speed. Each merge generates instant power spikes that directly impact your ability to survive progressively difficult enemy waves.
The combat calculation engine processes tower stats including damage per second, range radius, attack speed, and special abilities like splash damage or critical strike chance. Enemy waves scale based on a difficulty multiplier that increases wave health by 15-20% per level while introducing new enemy types with resistance modifiers. The game tracks your total damage output, gold income rate, and tower efficiency to determine upgrade paths and optimal merge timing.
Resource management drives progression through a three-currency economy: gold earned from defeated enemies funds new tower purchases, gems unlock premium tower types with unique abilities, and merge tokens allow instant tower combinations without grid placement restrictions. The auto-battle system can be toggled for passive farming, but manual play yields 30-40% higher gold income through strategic tower repositioning and merge chain optimization during active combat phases.

These spreadsheets are mathematically and methodologically incorrect for COBIT 2019. They are relics of COBIT 5 thinking. Use only for informal internal brainstorming, and never present output as a “COBIT 2019 maturity assessment” to management or auditors.
If you still want an Excel-based approach – download the official COBIT 2019 Process Assessment Model (PAM) from ISACA and build your own attribute-rating matrix. That is the only defensible spreadsheet method.
The COBIT 2019 Maturity Assessment Tool is a spreadsheet-based resource (XLS/XLSX) used by organizations to evaluate their IT governance maturity against the COBIT 2019 framework. Unlike its predecessor, COBIT 2019 shifts from the ISO/IEC 33000 scale to a Capability Maturity Model Integration (CMMI)-based scheme for assessing process capability on a scale of 0 to 5. Where to Find the Tool
Official ISACA Tool Kit: The primary version is part of the COBIT 2019 Tool Kit available on the ISACA website. You must scroll to "More Implementation Resources" to find the download link.
Third-Party Templates: Sites like ITSM Docs and Flevy offer enhanced templates that include pre-built scoring logic, RACI charts, and automated dashboards. Core Components of the XLS Tool
A standard COBIT 2019 assessment tool typically contains the following elements: Understanding the COBIT 2019 Framework: The 5 Core Domains
Overview
The COBIT 2019 Maturity Assessment Tool XLS is a spreadsheet-based tool designed to help organizations assess their IT governance and management maturity using the COBIT 2019 framework. COBIT (Control Objectives for Information and Related Technology) is a widely adopted framework for IT governance and management developed by ISACA.

The COBIT 2019 Maturity Assessment Tool XLS is suitable for: Cobit 2019 Maturity Assessment Tool Xls
Rating
Overall, I would give the COBIT 2019 Maturity Assessment Tool XLS a rating of 4 out of 5. While it is a useful tool for assessing IT governance and management maturity, it may require some knowledge of the COBIT 2019 framework and has limited customization options.
Recommendations
If you download the official ISACA tool or a derivative template, you will notice a specific architecture designed to calculate the "Capability Level."
The Inputs: The XLS sheet will typically list the 40 COBIT 2019 Management Objectives. For each objective, the tool breaks down the assessment into two distinct layers:
The Scoring Logic (The "N" Factor): This is the most misunderstood part of the tool. You are not simply picking a number between 0 and 5. You are scoring specific attributes on a percentage scale: Not recommended for professional or audit use
The Excel formulas embedded in the tool aggregate these granular scores to determine the final Capability Level (0-5). This granularity prevents the "optimism bias" where leaders rate themselves a 3 simply because they held one meeting on the topic.
Before diving into the Excel tool, we must understand the metric. COBIT 2019 moved away from the outdated "Capability Maturity Model Integration (CMMI)" levels (0 to 5) used in COBIT 5. Instead, it aligns with ISO/IEC 15504 (also known as ISO 15504 or SPICE).
The new maturity model uses six capability levels:
A maturity assessment measures your organization’s actual performance against these levels for each of the 40 governance and management objectives in COBIT 2019 (e.g., APO01 – Managed IT Management Framework, DSS02 – Managed Service Requests and Incidents, etc.).
